I am currently a Senior Applied Scientist at AWS Agentic AI working on large language models (LLMs) and agentic AI. Previously, I was a Postdoctoral researcher at MIT CSAIL, working with Regina Barzilay on AI for chemical sciences. I started my academic journey on NLP from HIT SCIR, under the supervision of Haifeng Wang and Wanxiang Che, and was a visiting student at Johns Hopkins University, advised by David Yarowsky.

My research interests span a broad spectrum of topics in natural language processing (NLP) and machine learning. My recent work includes:

• Post-Training — Amazon Titan LLMs
• Text-to-SQL — Amazon Q in QuickSight
• IR / RAG — Amazon Bedrock Knowledge Bases
• Agent Memory — Amazon Bedrock AgentCore
