Ben Lengerich

Hello! I'm a Ph.D. student in the CS Department at Carnegie Mellon University, advised by Prof. Eric Xing. I've also been very blessed to spend time working with Rich Caruana at Microsoft Research (2019, 2020) and Chris Potts at Roam Analytics (2017). My work has been supported by the CMLH Fellowship.

Research Interests: Motivated by the promise of precision medicine and focused on methodology for uncovering meaningful patterns from complex data, which often contain heterogeneous samples with conflicting patterns. My thesis is focused on sample-specific models -- what would it mean if we could estimate models for each individual sample? For more, please refer here.

Defended my PhD Thesis Sample-Specific Models for Precision Medicine. Thanks to my thesis committee of Eric Xing, Zico Kolter, Ziv Bar-Joseph, Rich Caruana, and Manolis Kellis for all of their help.
