I am an Assistant Professor in the Department of Computer Science at Indiana University. I currently serve as co-PI of the NSF Center for Distributed Confidential Computing and am affiliated with the Security and Privacy in Informatics, Computing, and Engineering (SPICE) Center. I received my Ph.D. in Computer Science from Duke University, where I was advised by Ashwin Machanavajjhala and Kartik Nayak. My earlier work explored how multi-party computation and differential privacy can make encrypted databases practical.

Fall 2027 Two fully funded Ph.D. openings in my lab

Confidential Computing Systems: Secure systems for ML and LLM serving using CPU and GPU TEEs. Recent work: HOSS (CCS ’26), VELODB (S&P ’27), and BOLT (CCS ’25).
Formal Methods for Data Governance: Policy enforcement for AI and data pipelines using information flow control and formal verification. Recent work: PICACHV (Security ’25).

Experience in these fields is not required, but is a big plus. If interested, please email me your CV and a brief self-introduction.

Research areas

My research focuses on secure computing systems for data and AI. I build practical systems for computing on sensitive data with confidentiality and verifiable data-use guarantees. My work spans two directions.
