I am a Ph.D. candidate in Computer Science at UC San Diego advised by Dinesh Bharadia and Aaron Schulman. I am a part of Sysnet, CNS and WCSNG research groups. My research involves developing machine learning and signal processsing algorithms to solve different problems in wireless sensing, communication and security. My work is supported by IARPA and the Qualcomm Innovation Fellowship. I have also interned at Qualcomm for two summers, where I developed and implemented deep learning architectures and signal processing algorithms for WiFi sensing. You can download my resume from here.

Before joining UCSD, I got my B.Sc. degree in Electrical Engineering (Communication Systems) from Sharif University of Technology, under the supervision of Mohammad-Ali Maddah-Ali and Babak Khalaj. I worked on probabilistic modeling and designing efficient memory sharing algorithms for Big Data processing systems using information theoretic approaches.
