CIT 525
I'm interested in computer systems, especially distributed systems, operating systems, and privacy-preserving systems.
In Fall 2024, I'm not teaching. In Spring 2025, I'm co-teaching CSCI 1670/1690: Operating Systems with Tom Doeppner.
Outside of CS, I enjoy history, woodworking, biking, and art.

Personal
Before joining Brown, I was a postdoc in the PDOS group at MIT CSAIL. Prior to MIT, I spent several enjoyable years doing my PhD in the NetOS group in the other Cambridge.
You can find me on Twitter and GitHub. My wife, Julia Netter, is a political philosopher.
