I earned my Ph.D. in Computer Science from Purdue University, where I worked under the supervision of Prof. Dongyan Xu and Prof. Berkay Celik. My research interests are in the broad area of system security, focusing on audit logging, forensic analysis, data provenance, and cyber-physical systems (industrial control systems). My work includes designing and building innovative security frameworks through applying causality analysis, machine learning, natural language processing, and program analysis techniques.
