Bio

I am a second-year Ph.D. student at the Algorithmic Intelligence Lab at KAIST AI. My research focuses on developing efficient and safe methods for enhancing, aligning, and personalizing generative models, with an emphasis on large language models. I have broad research interests, including generative models, reinforcement learning from human feedback, AI safety, and nature-inspired intelligence, among others. I always strive to more deeply understand the fundamental (mathematical) principles behind everything I work on, though it's a lot challenging in general :-)

Previously, I worked as a senior software engineer at Google, developing machine learning methods to localize Google Assistant for low-resource languages. I also worked in Display Ads, building the ads backend system and enhancing auction algorithms for improved user experience. I received an MS in computer science from Stanford University and a BS in computer science with a minor in applied mathematics from Cornell University.
