Bio: I am an Assistant Professor in the Department of Computer Science and a member of the Wolfpack Security and Privacy Research (WSPR) Lab.
My research is dedicated to measuring and improving the security and privacy of computer systems, with a particular emphasis on telephone networks and software for mobile platforms. This work has addressed detection and measurement of mobile malware in the wild, identified systemic risks in developing world mobile money systems, and provided new techniques to distinguish legitimate and fraudulent phone calls. My research integrates knowledge from fields as diverse as signal processing and digital communications; data science, machine learning, and statistics; cryptography; program analysis; reverse engineering; and Internet and telephone networks.
