Hello and Welcome!

I am a computer science Ph.D. student at Brown University. I am fortunately to be advised by Prof. Stefanie Tellex and to work with Prof. George Konidaris. I received my bachelor of science degree from Berkeley EECS . I am grateful for the supports of the NSF Graduate Research Fellowship Program and Jack Kent Cooke Foundation Graduate Scholarship.

Research Interests

I am interested in building intelligent robots that can complete a broad range of long-horizon tasks in diverse environments provided with sparse reward signals. To that end, I am developing intelligent systems that can leverage structure in task specifications and environments for efficient planning and learning.

Fun Outside Work

I love reading books, playing basketball, hiking, camping and movies directed by Christopher Nolan. When I read, I listen to guitar or Jazz BGM. The books I recently read are The Road Less Traveled, The Autobiography of Benjamin Franklin, and How We Think by John Dewey.
