Sebastian Gomez Angel

I'm a Ph.D. candidate in the department of Computer Science at UT Austin. I'm part of the Laboratory for Advanced Systems Research where I'm advised by Michael Walfish. I'm also a visiting academic at NYU's systems group. My current projects study different aspects of systems, security, and networking.

I will join the department of Computer and Information Sciences at the University of Pennsylvania as an Assistant Professor in Spring 2019.
