Ben Lengerich

Hello! I'm a postdoc in the MIT Computational Biology Lab (PI: Prof. Manolis Kellis) at MIT CSAIL and the Broad Institute. My research is currently supported by the Alana Down Syndrome Center at MIT, supporting our aims of using contextualized machine learning to understand complex diseases. I completed my PhD at the CS Department at CMU, advised by Prof. Eric Xing.

Research Interests and Selected Publications

I research machine learning methods and build artificial intelligence systems to automate the process of scientific discovery. I am particularly interested in questions of automatically identifying and adapting to changing contexts. This research focus requires advances in interpretable machine learning, multi-task learning, and task representation learning, and finds natural applications in precision medicine and computational genomics of complex diseases such as Alzheimer’s Disease, Down Syndrome, and cancer.
