// Security Researcher · Malware Analyst · PhD Candidate

 

About

I am a doctoral student at Columbia University, dabbling in systems security research across two labs, CASTL and IDS.

I am very fortunate to be advised by Simha Sethumadhavan and Salvatore Stolfo.

Apart from doing research, I partake in marathons, wing chun, scuba diving and CTFs.

 

Research

I am broadly interested in all aspects of systems and software security. Exploring security as a full-system property, my research examines both attack and defensive techniques at the hardware-software interfaces of commodity systems.
