About

I am a Ph.D. student in the School of Computer Science at Carnegie Mellon University. Under the guidance of Eric Xing, I study machine learning and computational biology with the goal of building systems to answer meaningful questions.

During my undergrad, I studied math and computer science as a Braddock Scholar in the Schreyer Honors College at Penn State University. In my spare time, I enjoy backpacking, playing ultimate frisbee, and composing for piano.

Teaching

In Spring 2017, I am a TA for Prof. Jian Ma and Prof. Maria Chikina's course 02-410/710 Computational Genomics.

In Fall 2016, I was a TA for Prof. Chris Langmead's course 02-450/750 Automation of Biological Research: Robotics and Active Learning. I gave a lecture on active learning for Bayesian Networks [pdf].
