About Me
I am a senior software engineer at Roblox and work in the Data Protection team under InfoSec.
I received my Ph.D. in Computer Science from Virginia Tech (Advisor: Prof. Danfeng Yao). My research interests focus on combining machine learning approaches with network anomaly detection. Most of my work is on detecting stealthy malicious network requests using machine learning techniques. Additional research interests consist of data visualization and mobile security.
Outside of research, my interests include reading and playing tennis. I am also an avid fan of photography while traveling.
