About Me

I am currently a graduate student at MIT CSAIL advised by Adam Belay. My research focuses on designing operating systems and resource management techniques that make datacenters more efficient, with an emphasis on kernel bypass, scheduling, and system-level optimizations.

Prior to MIT, I completed my undergraduate degree at the University of Pennsylvania, where I worked with Nadia Heninger on applied cryptography and systems security.

I am currently on the academic job market! Curriculum Vitae
