About
I am an Assistant Research Professor in the department of Electrical & Computer Engineering at Carnegie Mellon University with a courtesy appointment in Computer Science. I am also a member of the Parallel Data Lab.
My current research focuses on distributed and cloud storage, new storage technologies, high performance computing, and storage for machine learning.
