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

My research interests are broad, but 80% of them go nowhere. Currently, my researches are on Information Theory in context of wireless sensing and communication. 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. Thus, from time to time I step out of fantasy land to work on building hardwares and 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:

• Digital Signal Processing (As applied for communication): Lattice reduction (lattice theory), estimation and detection theory, super-resolution methods.
• 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, information theory and adaptive hypothesis testing
• Hardware: Learning-based JCAS network design, GNURadio/Software defined radio timing-based indoor localization based on OFDM (This is part of my involvement in VIP and AFRL).

Non-academic interests:

• Philosophy and Common Law.
• Tennis. Played for over 10 years. I consider myself a 4.5 player.
• Strategic games including Chess (2000 rated) and Gwent: the Witcher Card Game, where I was the World Champion.
