About Me

Hello! I am a second year Ph.D. student in Computer Science at Carnegie Mellon Univerity, advised by Zico Kolter .

My Research area focuses on machine learning and its social impact. Primarily, I am interested in understanding the long-term social ramifications of data-driven decision systems. I am currently funded through the Ford Foundation Pre-Doctoral Fellowship.

Before CMU, I was a Post-Baccalaureatte Research Fellow with the Beckman Laser Institute at the University of California, Irvine, where I worked on automated analyses of in-vivo multi-photon microscopy images. Even earlier, I was an undergraduate at Hampton University in Mathematics with a minor in Computer Science.
