About Me
I am a fourth-year Ph.D. candidate at Dartmouth College, advised by Prof. Peter Chin. I am also a fully funded PhD Innovation Fellow (NSF Research Traineeship, Thayer Engineering & Tuck Business collaboration), supervised by Prof. Eric R. Fossum on research translation and entrepreneurship. I hold an M.S. in CS (Intelligent Robotics) from USC. I interned at Microsoft Research Redmond and the Allen Institute for AI (Ai2).
About My Research
Can we build a general thinking machine that really creates knowledge beyond imitation in the real world? Towards this goal, I study the theoretical foundation of its feasibility at the representation level (ICLR’24 “TDL”). The actual design of “thinking” agents follows the definition from AIMA, environment modeling and a center framework (ICLR’24 Spotlight “SocioDojo”), lifelong memory (FinAI@ICLR’25 “AAPM”), adaptation and personalization (ACL’26 Findings “Apeiron), and reasoning (ICLR’26 “Analytica”). Finally, extends to evolution and discovery (NeurIPS’25 Spotlight “Genesys”).
They condensed to my agentic systems engineering frameworks. I design 🧊LLLM for local systems and 🌕SSSN for networked systems. Check live demos of my flagship systems below (click to explore, swipe left-right). In particular, I developed an 🧠Analytica web app for LLM-agentic analysis.
Analytica
Robust and efficient wide and deep LLM-agentic analysis and forecasting with soft logic and parallel Jupyter Notebook analysts.
Genesys
Distributed discovery system for novel language model architectures with autonomous design and evaluation.
Apeiron
Large-scale app synthesizer that models the full lifecycle autonomously, optimizing user demands with multi-thread CUA evaluators.
SocioDojo
LLM agentic lifelong societal modeling and analysis with news feed and real-time data flow. A "Human World Model".
