I am an Assistant Professor at the College of Information and Computer Sciences, University of Massachusetts Amherst. I am affiliated with the UMass Cybersecurity Institute.
My main research interest is cryptography, in particular the design and analysis of protocols with novel security or functionality properties relevant in emerging applications of cryptography. I am also interested in improving the analyses of widely-used protocols such as Schnorr signatures and its derivatives, as well as the post-quantum Fujisaki-Okamoto encryption transform. This work entails developing new computational hardness assumptions and proof techniques. You can find some statistics about my research on my Google scholar profile.
More specifically, topics I am working on include:
- Encrypted search, in particular property-preserving encryption
- Advanced signature schemes such as aggregate and threshold signatures
- Analysis in idealized models such as the random oracle model
- Functional encryption, for example inner-product functional encryption
