I am a fourth year Electrical and Computer Engineering Ph.D. student at the University of California, Los Angeles. I am a graduate student researcher in the Secure Systems and Architectures Lab advised by Professor Nader Sehatbakhsh. My research focuses on providing unconventional solutions for resource-constrained IoT devices using side-channels. For example, I have developed SideComm (communication via side-channels) and Digitus (authentication via side-channels).

Additionally, my research entails developing new end-to-end systems across the entire stack. This includes transmission and reception, firmware, toolchains, and security. My research interests include, but are not limited to, embedded systems, IoT, security, side-channels, and computer architecture.

Each day brings an opportunity to learn something new. Go Bruins!

Interests

Besides my interests in ECE, I enjoy many activities such as playing basketball and juggling. I also like to hang out with friends and grab a bubble tea.

I have enjoyed exploring the Los Angeles area and visiting places such as Venice Beach and Griffith Park.
