Assistant Professor
Dept of Computer Science
Yale University

I’m broadly interested in computer security and applied cryptography, especially techniques that enable Secure Decentralized Systems, a novel class of computer systems with unique security properties (such as transparency, verifiability, decentralized trust and governance).

My research aims to advance the technical foundation of decentralized systems, analyze the security of real-world deployments, and build practical tools to support applications in socially important domains.

I’m also affiliated with IC3, Center for Distributed Confidential Computing (CDCC) and Center for Algorithms, Data, and Market Design at Yale (CADMY).

At Yale, I teach Intro to Blockchain and Real-World Cryptography.

Research: Secure Decentralized Systems

Building computer systems with transparency and integrity guarantees is a dream of security and cryptography research. As society grows more dependent on digital infrastructure, this goal is more urgent than ever. Over the past decade, Secure Decentralized Systems, powered by cryptography and large-scale consensus protocols, have emerged as a promising path toward this vision, with early success in areas like stablecoins and Decentralized Finance.

My research advances the technical foundations of decentralized systems to enable transformative applications. Specifically, I work on:

  1. Design and improve cryptographic building blocks for decentralized systems,
  2. Identify and defend against attacks driven by economic incentives, and
  3. Enable and secure novel applications, including decentralized finance, social media, and AI.
