Personal Website: I launch this personal website to record my research history.
About me
I am a fifth-year Ph.D. student in the Institute for Data, Systems, and Society (IDSS) at Massachusetts Institute of Technology (MIT), advised by Professor Ali Jadbabaie. I am affilated with the Laboratory for Information and Decision Systems (LIDS). I am broadly interested in dynamical systems, networks, and machine learning on combinatorial structures and relational data. In particular, I am interested in the understanding attention mechanism in graph neural networks and transformers-how it gives rise to the emergence of "intelligence" beyond scaling laws.In the summer of 2024, I interned at Snap Research, working on enhancing the scalability of large-scale recommender systems using graph-based approaches under the mentorship of Dr. Tong Zhao.
Prior to coming to MIT, I was an undergraduate student at Washington University in St. Louis. I completed my senior thesis on quantum graphs with Professor Renato Feres.
