I’m an incoming Assistant Professor in the Computer Science Department at Johns Hopkins University, starting Fall 2026. I’m looking for motivated students interested in empirical work in network security and privacy. If that sounds like you, please get in touch!

My work focuses on security and privacy vulnerabilities that affect real people on the Internet. I collaborate with government and industry partners to understand and address these problems. I enjoy exploring the systems we all rely on—knowingly or not—and often assume to be secure or private. I like building tools to measure new phenomena and collect new data, and run the IPv6 Observatory.

Outside the lab, I’m an alliteration advocate, serial comma champion, diaeresis disciple, ligature lover, and semicolon supporter. Kerning is pretty groovy. I’m also an erratic (ultra)marathoner, erstwhile Marine, and devoted dog enthusiast. My Erdős number is 3 (Gera → Chartrand → Erdős).
