About

I am currently the Research Manager of the Biomedical and Clinical Informatics Lab at the University of Michigan, under the direction of Kayvan Najarian. Previously, I was a Ph.D. student at The Graduate Center, CUNY; as well as the Infrastructure Manager of the Westport Public Schools.

My research interests are in theoretical computer science, with a focus on machine learning, cryptography, and computational group theory, and well as computational medicine and computer networking/network security.
