I am a Ph.D. student in the Computer Science department at Purdue University, I work under the supervision of Prof. Dongyan Xu and Prof. Berkay Celik. My research interests lie in the broad area of system security with a current focus on audit logging, forensic analysis, data provenance, and cyber-physical systems (industrial control systems). I specifically focus on designing and building innovative security frameworks through applying causality analysis, machine learning, natural language processing and program analysis techniques.
