I build AI agents and the systems underneath them. Right now that means co-founding Civitas, sparse-attention serving with Prof. Vincent Liu, and a biofeedback browser extension called Cortex. I like the point where a model hits the real world — latency, state, ambiguity, humans.
Hongcheng Big Data Institute · Nanjing University
Research Engineer
Graph-structured long-term memory for LLM agents — retrieval that surfaces the right context across long horizons.
Paperboy
Agent Engineering Intern
Built a deterministic Record/Replay test service for the core agents and a pluggable evaluation harness for autonomous agents.
Distributed Systems Lab
Research Assistant·Penn Engineering · Prof. Vincent Liu
Ongoing Research Project: an LLM serving engine fusing FlashInfer tensor cores with tree-structured sparse attention, 1.36× faster than SGLang.
Past Research Project: FullStackArena, a 1,000+ task benchmark for browser agents in dynamic full-stack environments (submitted to NeurIPS 2026).
Penn EALC
Research Software Engineer·Prof. Hsiao-Wen Cheng
A digital-humanities platform with NLP entity extraction and faceted search across 2,700+ Song-dynasty literary works. Awarded a 2026 Summer Fellowship from the Greater Philadelphia Asian Studies Consortium — two selected each year.
Franklink
Founding Engineer
An iMessage-native networking agent — LangGraph orchestration with a two-stage embedding + LLM matching engine.
Huatai Securities
Derivatives Valuation Intern
Refined Gaussian HJM models for interest-rate swaptions; cut pricing turnaround from two days to four hours.
AutoPaperLab
Honesty-first research-to-paper pipeline — every citation, number, and result traces to something real, or it never ships.
OpenAgentDojo
A dojo for supervising deliberately-flawed coding agents — graded on process, not just the patch.
Cortex
Webcam heart-rate biofeedback (rPPG) that nudges you toward recovery in real time.
