Tell us about your research

My research is focused on tunable lasers with ring-based mirrors and their applications in photonic integrated circuits (PICs) using the hybrid silicon­III/V platform developed at UC Santa Barbara.  After developing a tunable laser I have been working on developing a chip for free-space beam-steering. An optical phased array has been integrated with fast phase tuners, on­chip tunable lasers and amplifiers, and on­chip feedback for a robust fully integrated PIC with more than 100 I/O signals. These PICs are useful for LIDAR and point­to­point communication applications and should be more robust, more compact, and faster than conventional devices.

How and why did you get into your area of research?

I have always been interested in light and its many applications. I was impressed with the Bowers group and the work they had done and I decided I wanted to be a part of the group. After joining, I did some work on the beam-steering project and got interested enough to continue with it.

Why did you select UCSB and ECE in regards to your research?

Originally, when I was looking into graduate schools I was intending to study a different field. However, as I saw the work done in different groups in the field of photonics I kept getting excited by the ideas and the results that I saw. I decided to change my focus, and soon afterward I saw The Institute for Energy Efficiency's "White Room" page. After seeing the focus and vision they had I decided that UCSB was where I wanted to do my research.

What do you find rewarding about your research?

It has been exciting seeing our systems expand as small components are successfully integrated together to create new functionality. Particularly rewarding has been the experience of being challenged in new ways. Research is frustrating and difficult, but I feel like I have grown a lot through participating in it.

UCSB prides itself on its collaborative atmosphere, give some examples of how you collaborate

The Bowers group, and the larger ECE department at UCSB, are incredibly helpful. There is a wide range of expertise, and I have found that everyone I talk to is willing to share their knowledge and spend time to help other people succeed.

Thoughts on working in a group research environment and your experience working with an advisor

Working in a group is really motivating. Having other students to ask questions to helps you get through the snags that repeatedly show up in research. Also, an experienced advisor like John Bowers is invaluable. He helps us set a direction and then gives us a lot of leeway on how to pursue it, but he is still involved and asking questions and giving us advice throughout.

Where will your research take you next?

For the future, I plan on taking the entrepreneurial track. I am currently collaborating with two other graduate students from the Materials Science and Economics departments on building a technology start-up in the high-power white-lighting industry.

Jared's thoughts on the academics at UCSB

Strengths of the graduate program

We have world-class professors here. They know their subjects very well and also have a lot of real-world experience, so nothing is taught in a vacuum. The clean room and lab facilities are fantastic. Also, I have found the Technology Management Program to be very valuable. This program is aimed at teaching students the basics of business and helping them transition their work into industry.

Favorite course

Some of my favorite course have been Larry Coldren's courses on lasers and Umesh Mishra's course on device physics. These are some of the most applicable classes I have ever taken.

Describe your experience as a Graduate Student Researcher (GSR)

Being a graduate student researcher has been a rewarding experience.  It has allowed me to focus all my efforts on research without worrying about funding or classes.  Research is hard enough without extra responsibilities, and I have plenty of extra responsibilities outside of UCSB.

Experience with the graduate exams

The screening exam was challenging. I spent seven weeks one summer with studying every day for eight hours and then meeting with several friends at least weekly to do practice tests. It was actually quite liberating to have time set aside to study the things that I hadn't quite understood in classes, and I really appreciated it. In the end, the exams were not as bad as I imagined. They did require the study I had put in, but I found that the professors were encouraging and wanted me to succeed. I learned new ways to look at the physics from most of the exams and I went away very happy with the experience.

Life as a graduate student

Quality of life as a graduate student and how you balance school, work, social, and family life

Balancing time is by far the hardest part of graduate school for me. I have a wife and two children under the age of four. I am also involved in service through the LDS church. I always feel like I should be working 12 hours a day to meet my research goals, and when I am taking classes it is even more difficult. Add the company I am trying to start and there simply isn't enough time to do everything I think I should. For much of my graduate career I have neglected sleep to find the needed time. I do not recommend this for extended periods of time as it becomes increasingly difficult to think clearly and is pretty depressing. So now I am simply doing my best, usually just working 8 hours a day and making sure I am spending time with my kids most nights and on the weekends. My social life is mainly through church and the occasional dinner at our apartment with friends.

Where do you live?

I am living in Family Housing because it's conveniently close and it's all I can afford in the area. I enjoy the weather here, but I personally miss most of the benefits of living in such a beautiful location because of time constraints. I do appreciate that my wife and children have easy access to the beach, hiking trails, etc.

What do you do over Summer break?

Most summers are spent doing research at UCSB, and I expect this year will be the same.

Advice to prospective graduate students

Graduate school is hard. Make sure you have a dream or goal or something that will get you through the lows and help you to keep going.

Tell us about your research

My current research focuses on high level abstractions and methods. In digital system design, high level abstractions and methods become more and more a necessity due to the increasing system complexity. They are crucial to design productivity and enable designers to keep up with the trend of industry. However, current high level methods have a hard time balancing between high quality and low algorithm complexity. Current state-of-the-art methods have at least cubic complexity which is not acceptable for large designs. In my research, we propose hierarchy-based stochastic algorithms which are scalable and can generate high quality designs. Compared to the state-of-art algorithms, ours can generate better results while having a complexity which is one magnitude lower.

How and why did you get into your area of research?

When I was an undergraduate, I always wanted to build some real working systems. I had a lot fun experiences using single-chip microprocessor and wanted to look more into this field. When I got to UCSB, I did not hesitate to join the computer engineering group because I knew I could learn what I wanted to learn. After exposing myself to different research fields, I found that the research opportunity that Professor Forrest Brewer offered was a perfect match for me. I was attracted not only to the projects, but also Forrest's enthusiasm, passion and wisdom. Also, the open and free research environment of his lab made me believe even more that this was the lab I had been looking for.

Why did you select UCSB and the Electrical and Computer Engineering Department in regards to your research?

UCSB's ECE department has a great reputation in the world. There are a few professors doing great research in Computer Engineering. The job market for UCSB students is great. One can choose to work in big/small companies or become faculties in prestigious schools. Finally, it is the unmatchable ocean view that made me push the button.

What do you find rewarding about your research?

Research is all about finding the right problems, solving them using the right approaches and presenting them in a clear way. It is not easy to get. You need to be smart, creative and persistent. However, once you get there, oh man, life can never be better.

UCSB prides itself on its collaborative atmosphere, give some examples of how you collaborate

Ph.D. students have no difficulty finding new ideas. The problem is about which ideas are the right ones. We don't have enough time and energy to try them all. This is where your advisor comes to play. My advisor can provide insights on these problems and ideas and guard me in the right direction. However, no matter how good and knowable your advisor is, there is always something that you need to decide yourself. You need to come up with new ideas, choose the right one from a smaller pool of them and find out the right way to solve them. This is how you become a real Ph.D.

Thoughts on working in a group research environment and your experience working with an advisor

Choosing an advisor and a research group is crucial to a Ph.D. student. I really think this should draw all Ph.D. students' attention. Ph.D. is a long time commitment, five years on average. During this period, you need to work with your advisor and your lab mates a lot, if not every day. The way they think and behave will unconsciously affect you. Finding a great advisor is as important as finding a great project. A great advisor is an advisor whose research attracts you and whose thinking and working styles match yours. My lab has always been a lab which is open to new ideas, new challenges and new people. The lab is always full of new exciting ideas both from our advisor and students.

Where will your research take you next?

After graduation, I would like to work in industry. For engineers, the ultimate goal is to solve practical problems. In my field, I believe most of the valuable and interesting problems come from industry. It's time show my "weapons".

Wei's thoughts on the academics at UCSB

Strengths of the graduate program

I believe the faculty and staff are the strengths of the department. Professors love what they are doing and are always there to teach, help and encourage students. I sincerely believe getting the job done is not their primary goal. Their goal is to get things done to the best benefits of students. Staff are always there to help, too.

Favorite courses

It is hard to select one favorite course because I have had so many fun classes. Introduction to Design Automation(ECE256A) was one of them. I took this class the first quarter I was at UCSB. Back then, my English was extremely bad. I could not follow professors in classes and was afraid to ask questions. The consequence was that I needed to spend at least twice as much time as other students, if not more. However, the idea of using mathematical algorithms to solve practical problems kept motivating me, and the final project was a lot fun.

Experience with the graduate exams

For the screening exam, join a study group. If there is not one, establish one. A study group is so great and brings so much efficiency and fun to your study. For qualifying exam, presentation is about everything. Also, make sure you can describe your research clearly within 40 minutes.

Describe your experience as a Graduate Student Researcher and/or Teaching Assistant (TA)

I've been a GSR and a TA several times. A GSR has to be highly self-motivated, creative and hard working. Besides, GSRs need to train themselves with presentation skills. No matter how good your research is, its value will be jeopardized if you don't know how to present it. I TAed Digital Design Principles (ECE152A) and Hardware / Software Interface (ECE153A/253). In both classes, I led lab sections. In ECE153A/253, I held discussion sections too. I am an international student. English is my short slab compared to native speakers. However, one can always work out something else to compensate their disadvantages. Patience coupled with my teaching philosophy is my secret. A TA is a teaching assistant — we are there to assist with teaching. Grading homework and leading labs are basic work. So, why are we doing this? We are doing this not to fulfill our TA 50% duty but to make sure students understand class materials. If they are not, help them.

Life as a graduate student

Quality of life as a graduate student and how you balance school, work, social, and family life

The most important thing about graduate school is study. The knowledge you require from school and the way you think. You need those in order to be competitive in the job market. However, study is not everything. Socialization is important too. I found that planning ahead helps a lot with balancing between school and work. Graduate students all have busy lives. It's quite often that when you have time, others might not. Planning ahead can minimize this conflict.

Where have you lived while at UCSB?

I live in Goleta because it is close to school. From Monday to Friday, I spend most of my time in school. However, I will have casual lunch or dinner with my friends during work days. In the weekend, I will hang out with my friends, holding parties, potluck, shopping or karaoke in LA. If weather permits, we sometimes go hiking. Seven Falls and Red Rock are favorite hiking trails.

Advice to prospective graduate students

Choose your favorite research group, develop some ocean related hobbies, join some clubs. Most important, enjoy life!!!!

  • Types of financial assistance received: National Science Foundation-Louis Stokes Alliance for Minorities Program - Bridge to the Doctorate (NSF-LSAMP-BD) Fellowship (2 years), TA ship (4 quarters), and GSR (currently)

Tell us about your research

My current research explores the effective design and deployment of wireless sensor networks for healthcare. More specifically, the title of my current project is "Multimodal Sensor Network: A Systems Approach to Analyzing Patient Well-Being and Disease States."

How and why did you get into your area of research?

As undergraduate research assistant in the Healthcare Robotics Laboratory at the Georgia Institute of Technology, I was introduced to a project that combined engineering and medicine to improve, in this particular case, the quality of life of ALS patients. I enjoyed being part of that project, and I loved the feeling of belonging and knowing that my research would impact someone’s life in a positive way.

Why did you select UCSB and ECE in regards to your research?

I came to UCSB in hopes of joining one of the very successful Control groups in the CSSP area at UCSB. That was before learning what controls really is and I realized that controls was not for me. After dealing with the shock (which took me some time and lost sleep), I changed focus which I believe was for the best. The faculty at UCSB are supportive and flexible, allowing students to pick and try different areas of research. I also had a two-year fellowship from NSF-LSAMP-BD through the California NanoSystems Institute (CNSI) to attend UCSB — funding is always a great motivation to attend a graduate program.

What do you find rewarding about your research?

I am particularly interested in healthcare and the potential short-term application of my research. I believe that with a direct application to healthcare my research can become a great contribution and, perhaps, the basis for providing individualized care and improving quality of life of patients and elderly frail.

UCSB prides itself on its collaborative atmosphere, give some examples of how you collaborate

The ideas that led me towards my current research put me in contact with Scott D. Hammond, M.D., and executive director of the Translational Medical Research Laboratory (TMRL) at the Center for Bio-Engineering (CBE) at UCSB and the Santa Barbara Cottage Hospital. Dr. Hammond, my co-advisor, provides me with the medical background advisement and the expertise necessary to identify and tackle various healthcare problems as defined by the current project. My research advisor, Dr. Manjunath, provides me with scientific advisement and mentoring in the engineering field. With the guidance of both, advisor and co-advisor, I am hoping to effectively combine engineering and medicine to improve hospital efficiency and healthcare services. A project that combines engineering and medicine can only be envisioned by a strong collaboration between these two fields. Furthermore, the VR-TMRL collaboration opened Santa Barbara Cottage Hospital’s doors for potential deployment and testing of the proposed network in real healthcare environments.

Thoughts on working in a group research environment and your experience working with an advisor

I felt like I was in limbo for some time, after deciding that controls was not for me. Fortunately, my current advisor allowed me to defined my own project and path, which was stressful and time consuming, but I am happy and excited about my new project and the direction my career has taken. My advisor was open to the idea of combining healthcare and engineering and my research group is awesome and supportive. My advisor directs the Center for BioImage Informatics and the Vision Research Lab, together there are about 20 students and we all get along in and out of the lab. We spend a lot of time together talking about research and life,... they have become my second family. Labmates are important, they can be the only support when times get tough (and they will get tough if you are a graduate student).

Where will your research take you next?

I am very fond of academics but I hope that my current path leads towards a successful research career in industry. I envision either joining a start-up company or starting one. I would like to serve as a mentor for younger Latino generations and help to improve my community. I have volunteered to serve as a mentor for summer research programs and have tried various approaches (hands-off and micro-management) in order evaluate my own strengths and weaknesses as mentor and hopefully improve upon these experiences.

Carlos' thoughts on the academics at UCSB

Strengths of the graduate program

The strengths are approachable faculty and hardworking students. The department has a limited number of classes that are taught by experts on the various fields. In my opinion, the department focuses on quality of graduate courses rather than quantity and I really like that.

Favorite course

Ironically enough, my favorite course was Fundamental of Speech Processing taught by Professor Lawrence Rabiner. It was not my best course, I would go as far as to say that it was my weakest topic (especially the theory). I never did so poorly in a class as I did in that one but I liked it because it forced me to learn and re-learn signal processing basics. It was also a very hands-on class and I enjoy programming and implementing algorithms.

Experience with the graduate exams

Among the ECE students, the screening exam has a nickname “Screaming Exam”. Preparing for the exam and going through it has been a humbling and terrible experience. I would not do that again. Now that my research is moving along, I hope to be able to qualify later in the Summer or Fall 2013. I am currently preparing for it, drafting a plan, and consulting with my advisors.

Describe your experience as a Teaching Assistant (TA) and GSR

Being a Teaching Assistant (TA) is a humbling experience and I believe it is important to TA earlier in your career as grad student. The TAing experience can make taking the ECE screening exam not as dreadful. The bad side of TAing is that depending on the class and the professor it can take large amounts of time. I have TAed Computer Vision, Image Processing, Multimedia Systems, and Introduction to Programming for Engineers. They were all very fun courses and the Professors very reasonable and approachable. I like teaching, and I assume my students and Professors liked my style of teaching since I received the outstanding teaching award that comes with a nice cash price. I was also a GSR during the Summer 2012 quarter in the Vision Research Laboratory helping on a project that I am not longer working with.

Life as a graduate student

Quality of life as a graduate student and how you balance school, work, social, and family life

Graduate school is hard. Long hours, hard and stressful work, and low pay, so it is very important that you like and enjoy what you do and the project that “you decide to work on”. It took me some time, perhaps longer than the average, to pick an area and project I wanted to commit to; however, taking the time is important and it has been the best decision during my graduate education. Graduate student life is full of sacrifices, self-motivation, and hard work with not a lot of free time or money. However, it is essential to enjoy simple things like running on the beach, going out for drinks with friends. I have a relatively set schedule where I lay out how much time to devote to exercise, cooking, lab/research work, and friends. The time is not equally distributed, but it is realistic and knowing that makes me feel fulfilled.

What is your social life like and where have you lived?

When I am not in the lab I am running, climbing, working out at the gym, running, hiking, and sometimes surfing. I spend all of my free time outdoors, but I am trying to get back into playing music. I live in Goleta because is relatively close to campus, cheaper and more comfortable than graduate student housing, I have a yard, and get to pick my housemates. Also, I wanted to have a dog and living on campus was out of the question after adopting a pup.

What did you do over Summer break?

This past summer I was a mentor for two high school students, while working on some grant proposal. I was awarded a seed grant that is currently funding me. I am committed to the project for the next 9-10 months, so I will be at UCSB doing research all summer. However, I hope to squeeze in some major backpacking with my dog in the Sierras. I am planning on touring the 200 miles of the High Sierra Route, which runs parallel to the more famous John Muir Trail but at higher elevation.

Advice to prospective graduate students

Shop around for a good research group. Good meaning a group that is supportive, active, and that has projects that are interesting to you. Do not get group information from their websites, do not trust websites - 99% of them are not up to date. Instead read some of the publications (those are usually current) and then arrange meetings with potential advisors and their students. Ask a lot of questions ranging from research interest and technical question to group dynamics, responsibilities, expectations, and interaction outside the lab.

In her own words — Freshman to M.S. student to Ph.D. student at UCSB

My undergrad years as a Computer Engineering Program student at UCSB were awesome! There was a good mix of work and social life (though maybe not as much as other majors). The last year of undergrad studies was the best since the classes were so interesting. The Computer Engineering Senior Capstone Project (189A/B) was an experience that I will never forget... The process of our group taking an idea from scratch to a finished product was a lot of fun.

After receiving my undergraduate degree from UCSB, I decided to continue my education and get a M.S. degree. I chose to stay at UCSB over other schools because of the relationships I made with some of the UCSB professors. I wanted to continue to work with them and their research aligned with what I wanted to pursue. It was not my original intention to continue onto my Ph.D. but I enjoyed research so much that I decided to continue.

Tell us about your research

Analog components in system on chip designs (SoC) have proven to be very difficult to test within the digital design verification flow. These components are simulated and verified using SPICE, which can be time consuming for complex components. We propose a methodology for building System Verilog behavioral models for analog and mixed signal circuits directly from the circuit netlist. We show that it is possible to build models of complex non-linear circuits that can be used within a digital simulation environment for system level verification. These models capture the behaviors for different input stimuli and varying parameters, allowing system-level simulation of circuits composed of digital and analog blocks. In this methodology, a circuit description is converted into a directed acyclic graph that captures relationships among the sub-circuits of the netlist. Each node within the graph is modeled using ν-SVR (Support Vector Regression) and written as a System Verilog module. These modules can be used for system level simulation with and without injected errors as well as for sensitivity analysis.

How and why did you get into your area of research?

My research ended up changing three times since I started. Originally I worked in fault diagnosis of large scale digital designs, then moved to post silicon test program validation using pre-silicon design models, and finally changed to analog behavioral modeling using machine learning algorithms. I ended up in my present research area through numerous talks with industry contacts about how my expertise can be applied to applications that could directly benefit them.

Why did you select UCSB and ECE in regards to your research?

I stayed at UCSB to continue my education because of the professors and the environment. I have built great relationships that I wanted to continue to develop, plus you can't beat the view of the beach and the mountains.

What do you find rewarding about your research?

Solving relevant problems facing the industry today. Being able to take the research that is done at school and implement it within a company's flow is very rewarding.

UCSB prides itself on its collaborative atmosphere, give some examples of how you collaborate

Our project collaborates with an industry mentor at Intel who provides industry related feedback to proposed projects and ideas. We also collaborate with UCSB ECE Professor Luke Theogarajan's group who provide us with analog netlists and we perform our experiments on them.

Thoughts on working in a group research environment and your experience working with an advisor

Working in a group environment makes it easier to share ideas and solutions which ends up taking some of the stress out of the work. It has been a real pleasure working with my advisors especially since they provide me with excellent direction and advice while giving me the freedom to explore paths on my own.

Where will your research take you next?

I plan on exploring various aspects to behavioral modeling including design space exploration and scaling. I plan on entering industry but not necessarily in the same area as my research.

Samantha's thoughts on the academics at UCSB

Strengths of the graduate program

In two words — the professors.

Favorite courses

My favorite undergraduate courses were 189A/B (know as the Senior Capstone project) and Digital Design with VHDL and Synthesis (ECE 156A) and Computer-Aided Design of VLSI Circuits (ECE 156B) which gave me the direction I wanted to take for my higher level education. As for graduate courses, VLSI Design Validation (ECE 255) taught by Professor Li-C Wang and Introduction to Design Automation (ECE 256) taught by Professor Margaret Marek-Sadowska because the content and the projects were interesting and both were related to my field of study.

Experience with the graduate exams

The most memorable exam I have taken was the screening exam. I spent months studying for it which ended up paying off in the end. It was a tough and stressful test.

Describe your experience as a Teaching Assistant (TA)

I was a TA for Fundamentals of Logic Design (ECE 15A); Sensor and Peripheral Interface Design (ECE 153B); Digital Design with VHDL and Synthesis (ECE 156A); and Senior Computer Systems"Capstone" Project (ECE 189B) where I taught sections, provided assistance in labs, and graded homework and reports. Aside from the grading, being able to help the undergrads get through their tough classes was very rewarding. Helping them fine-tune their Capstone projects and sharing my experiences and mistakes hopefully made the process a bit smoother.

Life as a graduate student

Quality of life as a graduate student and how you balance school, work, social, and family life

It is not too much different than undergraduate student life. The main difference is that you are surrounded by more like- minded and goal oriented people. As far as balance goes, I've had to learn to become a good planner and not save things for the last minute.

Where have you lived while at UCSB?

I lived in various places in SB (Isla Vista also known as IV, Goleta, Downtown). Living in IV is great as an undergraduate and living downtown was a better fit once I became a graduate student.

What did you do over Summer break?

I worked at Intel Corporation in Hillsboro, Oregon this past summer. I worked in the analog CAD department, which is closely related to my research. It was a great experience to learn how things are done in industry and if I am not close to graduating next summer I plan on going back.

Advice to prospective graduate students

Try to experience everything Santa Barbara and UCSB has to offer, you may never get the opportunity to live here again!
