Short Bio. Since August 2025, I have been an Assistant Professor in the School of Computing and Informatics at the University of Louisiana at Lafayette. Prior to this, I was a postdoctoral researcher at the CISPA Helmholtz Center for Information Security (Mar 2023 - Jul 2025), where I worked with Prof. Thorsten Holz. I received my Ph.D. in Computer Science from the University of New Orleans under the supervision of Prof. Phani Vadrevu.
Research. My research lies at the intersection of Internet security, cybercrime, web security, and emerging AI-driven threats. I study how attacks and illicit activities operate at scale, the infrastructure and ecosystems that enable them, and how we can build proactive defenses. My work combines large-scale Internet and web measurements with empirical and systems-driven approaches to investigate real-world security and privacy problems.
My current research focuses on:
