About


I am a rising third-year Ph.D. student at Carnegie Mellon University, advised by Eric Xing. I am interested in statistical machine learning for healthcare and the theoretical problems that arise from the constraints of real-world data. These include building interpretable, robust systems for prediction on structured genomic, medical, and other types of data.

Previously, I studied math and computer science as a Braddock Scholar in the Schreyer Honors College at Penn State University. I did research with Sharon Hammes-Schiffer's Theoretical Chemistry Lab and Raj Acharya's ALISA lab. In my free time, I enjoy backpacking and composing for piano.

In Fall 2017, I will be co-founding the AI+ club at CMU. If you are interested in sponsoring talks, contact me by email.

Contact me on Twitter, by email, or in person.

Teaching


In Spring 2017, I was a TA for Prof. Jian Ma and Prof. Maria Chikina's course 02-410/710 Computational Genomics. I gave a lecture on statistical methods for discovering genetic associations [pdf].

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].

Software


GenAMap is an open source platform for visual machine learning of structured association mappings between genotypes and phenotypes.
