Welcome to my webpage!
I am PhD Student in Electrical and Computer Engineering Department at University of California, Santa Barbara. I work in Sensor and Robotic networks lab under Prof. Mostofi.
Before coming to UCSB, I spent two years at
DRDO, India where I worked on antenna design for radars. Prior to that I worked on LTE testbed at IIT, Madras for a brief period.

Head Counting with WiFi: Counting People Without Relying On Personal Devices
In this project, we estimate the total number of people walking in an area using WiFi signals. We utilize the scattering effects of people
in the surrounding area for this purpose. We probabilistically characterize the received power measurements of a WiFi link in terms of the number of people
in the area and use it to estimate the number. We tested up to 20 people in the area and could successfully count the number people. We recently extended this setup
to work through walls. Please visit the project page for more details.
X-Ray Vision for Robots: Seeing Through Walls with Only WiFi
In this project, we use a pair of ground robots equipped with WiFi transceivers to image the area. The area is completely unknown to the robots and
we image the area including the occluded areas using only the power of WiFi measurements. We model the wireless propagation using wave models
and utilize compressive sensing theories to extract the image from wireless measurements. Please visit the project page for more details.

I am fascinated with the fundamental working principles of our universe. I follow PBS SpaceTime Youtube
channel and Prof. Susskind's Theoretical Minimum courses.
I also enjoy playing tennis and I am a big fan of Roger Federer.
