Ph.D. Candidate in the Dept of CS, Purdue University. I am a researcher in the PurNET and NextGArch labs, working under the guidance of Prof. Muhammad Shahbaz and Prof. Sonia Fahmy.

I earned my B.Engg & M.S. from NUST, Pakistan, after which I spent ~4 years in the industry; starting as a Malware Researcher and eventually rising to the position of Assistant Manager before leaving to pursue my Ph.D.

My research interests lie in the areas of systems and architectures, with a focus on Security, Networks, and AI. Currently, I am developing NextGen architectural frameworks for large-scale and distributed AI/ML systems.
