About Me

I’m a first-year Statistics Ph.D. student with a specialization in artificial intelligence, advised by Dr. Song-Chun Zhu at the Center for Vision, Cognition, Learning, and Autonomy (VCLA) at UCLA. My emphasis is in natural language processing and generative modeling. Many projects are on my Github page.

I obtained a Master of Science in Computer Science with a specialization in artificial intelligence and a Bachelor of Arts in Philosophy with an emphasis in philosophy of language, both from UCLA.

Before my Masters, I worked as a Full Stack Software Engineer in the San Francisco bay area for 3 years.
