Press Release: G5 Labs is officially out of stealth with $14 million in seed funding!

About Me

I am a Co-Founder of G5 Labs.ai. Previously, I was an Applied Scientist in AI Fundamental Research at AWS. I did my PhD in Computer Science at Cornell University, where I was fortunate to be advised by Prof. Immanuel Trummer.

Research Interests

I am particularly interested in building efficient data systems involving LLMs and ML models. At Cornell, I developed an LLM framework that automatically selects minimum-cost LLMs while ensuring sufficient result quality. I also built an approximate query processing system for multi-modal data on top of an RDBMS, ML models, and LLMs.

Work Experience

During my PhD, I interned with the Learned Systems Group at Amazon, where I worked with Kapil Vaidya, Murali Narayanaswamy, and Prof. Tim Kraska on LLM pipelines for Text2SQL (Amazon Q generative SQL). I also interned with the Data Systems Group at Microsoft Research, collaborating with Tarique Siddiqui, Wentao Wu, and Chi Wang on query workload compression for index tuning.
