Bio

I am an Assistant Professor at Fordham University in the Department of Computer and Information Sciences, located at the Lincoln Center campus in New York City. I am broadly interested in the intersection of computer systems, security, and economics, with a focus on how architectural and economic incentives shape the cybersecurity ecosystem. My research combines systems building, measurement, and modeling to better understand and improve the security and resilience of computing infrastructures. I received my PhD in Computer Science from Columbia University, where I worked under the supervision of Prof. Simha Sethumadhavan. I am currently recruiting motivated PhD students to join my research group. If you are interested in working on problems at the intersection of systems, security, and economics, please reach out. |
