About me.

I'm a third-year Ph.D. student at Purdue CS working with Professor Elisa Bertino. I did my internship at Tursio.ai this summer, where we turned databases into generative AI machines together.

My interests span Data Management for LLMs and their applications in different domains (such as Agentic RAG & Recommendation Systems) while ensuring security. I have publications both in data management for data-centered LLM application workloads (Vexless@SIGMOD2024), and integrating AI into data management systems (LLM-based Semantic File System for AIOS, submitted to ICLR 2025). Specifically, now I focus on enabling large language models (LLMs) to retrieve and reason with varied data sources effectively, to enhance the trustworthiness and efficiency of ML models/LLMs utilizing real-world knowledge. Those varied data sources include:

• Unstructured data (vector data): e.g., semantic embeddings of multi-modal data, etc.

• Structured data: e.g., tabular data from RDBMS.

• Semi-structured data: e.g., graph data.

Before my Ph.D. journey, I was a CS undergraduate at the School of Computer Science and Engineering at Sun Yat-sen University from 2018 to 2022. I worked as a research intern at the System Research Group in Microsoft Research Asia and SAP Labs. 

Please don't hesitate to reach out to me if you are interested in a discussion or collaboration.

Thanks to the easygoing upbringing my family and alma mater gave me, I have a bunch of hobbies, like hitting the trails and snapping some pics. I used to practice Nunchucks and Taekwondo, but those moves, including my favorite, Taegeuk Pal Jang, have slipped my mind these years. To know more about me, please have a brief glimpse of my Miscs and my Adventures.
