About Me
My name is Xuan-Bach Le, and I am presently a postdoctoral researcher at NTU in Singapore under the supervision of Professor Luke Ong. Additional information about my background and work can be found here.
I studied Double-Degree Program in Computer Science and Pure Mathematics (taken courses) at NUS (Singapore, 2007-2012). I then obtained my CS PhD from NUS (2013-2017) under the supervision of Aquinas Hobor and mentorship of Anthony W. Lin.
Research Interest
I am interested in both the practical applications and theoretical foundations of Computer Science. My research topics include (but are not limited to) developing logical frameworks/(certified) decision procedures for program verification, as well as establishing the decidability and computational complexity of the underlying logics. Recently, I’ve started to do research in Reinforcement Learning. This is my recently published neurips paper.
