Ph.D in Electrical and Computer Engineering advised by Prof. Matthieu Bloch.

My research interests are broad, except 80% of them go nowhere. By way of background, my current researches are on Information Theoretic analysis of communication, sensing and learning systems. My backgrounds are in communication theory and signal processing as applied to communication. I am interested in theoretical analysis of fundamental challenges in wireless communication in providing intuitions for practical systems.

Previously, I received my BS in Electrical Engineering with highest honors in 2022, also at Tech. My BS/MS advisor is Prof. Xiaoli Ma, and my thesis titled “Performance Analysis and Algorithm Design for Chirp-based Multicarrier Systems,” which involves the use of non-linear transform basis in multicarrier systems and its related algorithms and performance characterizations.

Specifically, my researches include:

• Communication Theory: Algorithm design and performance characterization for multicarrier systems (DAFT,OCDM,OFDM): e.g., Diversity and coding gain analysis, CFO estimation algorithms, Adaptive Modulation, Equalization …
• Information and Coding Theory: Information-theoretic joint communication and sensing (JCAS), physical layer security and adaptive hypothesis testing (sequential decision making), Information-theoretic analysis of LLM steganography, etc.

I am also “supervising” the vertically integrated project (VIP) team agile communication at gatech (started 2022), which is the extent of my experience in hardware

• Hardware: GNURadio/Software defined radio timing-based indoor localization (VIP and AFRL).

Non-academic interests:

• Tennis. Played for over 10 years. I consider myself a 4.5 player (Though recently kinda improved a bit, so maybe a 5).
• Strategic games including Chess (2000 rated) and Gwent: the Witcher Card Game, where I was the World Champion.
