My research interests broadly cover security and privacy aspects of large online services. I am particularly interested in the emerging space at the intersection of machine learning and security. Three research directions include: (1) Attacks using ML: Investigating how recent developments in ML can be misused to abuse online services. (2) Attacks on ML systems: Understanding vulnerabilities of ML systems (e.g., Face recognition) and improving robustness. (3) ML for better security/privacy: Leveraging advances in ML to build better defenses against attacks on online services.
I completed my Ph.D. in Computer Science at the Max Planck Institute for Software Systems where I was advised by Prof. Krishna P. Gummadi and Prof. Alan Mislove. Before joining VT, I spent ~2 years as a Postdoc in SAND lab (at UCSB and UChicago) working with Prof. Ben Y. Zhao. Prior to that, I spent a year as a Researcher at Nokia Bell Labs, Stuttgart.
I am looking for students to work on research projects. VT undergrads are especially encouraged. Email me if you are interested!
