Curriculum Vitae (Updated by Jul 2023)

I am an assistant professor in the Department of Computer Science at Indiana University. I am also affiliated with Luddy’s Security & Privacy in Informatics, Computing, and Engineering (SPICE) Center. I received my Ph.D. in Computer Science from Duke University under the supervision of Ashwin Machanavajjhala and Kartik Nayak.

My research focuses on developing full-stack solutions for privacy-preserving data sharing and analytics (PPDSA), which spans theory, systems, and architecture advancements. Specifically, my current current research can be summarized as follows:

Theory
- PAC based privacy methods (Usenix 23)
- Synergy of cryptography and differential privacy (SIGMOD 20, 21, 22)
Systems
- Private data federation and encrypted databases (IncShrink, Special, FL-NLP)
- Learning-augumented PPDSA systems
Architecture
- Leakage-resistant TEEs (Micro-architecture and ISA)
- Hardware acceleration and synthesis for PPDSA (MICRO 23, NeurIPS 23, DAC 23, ICCV 23)

I am looking for (i) Ph.D. students with fully-funded RAs; (ii) Postdocs. If any of the research topics capture your interest, feel free to drop me an email. More details can be found here

Jan 17, 2025	Two papers have been accepted recently: Haobin’s paper (with Hongbo, Mingshen, and XiaoFeng) on formally verified enforcement for data-in-use policies has been accepted by Usenix Security 25, congrats! This also marks my first advised student paper at IU. My paper (with Lina, Johes and Yukui) on Synopsis Assisted Secure Collaborative Analytics has been accepted by VLDB 25. Interestingly, as a DB researcher, this is my first VLDB paper—likely because I’ve primarily submitted to SIGMOD in the past.
Jul 12, 2024	Our proposal on Usable Private Data Federation has been awarded by the NSF CICI program.
Jul 31, 2023	Check out our latest posts (with Kartik) on Decentralized Thoughts that explain the key intuition in our work on private proof-of-stake blockchains, part1, part2, and our talks on Zcon4.
Jun 21, 2023	I defended my Ph.D. today.
May 9, 2023	Our paper (with David, Kartik, and Ashwin) about Private Proof-of-Stake Blockchains using DP Stake Distortion has been accepted by Usenix Security 23.
