I am a Ph.D. candidate in the Computer Science Department at North Carolina State University and a member of the Wolfpack Security and Privacy Research (WSPR) Lab. I am advised by Dr. Brad Reaves. Previously, I developed and troubleshot VoIP systems at Cisco.

My research interest spans the area of system security and privacy, with an emphasis on developing and applying data-driven techniques to study spam, abuse and fraud. I currently work on developing techniques to detect and characterize Robocalls — a catch-all term for automated or semi-automated phone calls. Our recent work on characterizing robocalls won the 2020 First Place Internet Defense Prize and a Distinguished Paper Award.
