Ertza Warraich
I am a Ph.D. candidate in the Department of Computer Science at Purdue University, where I am conducting research in the PurNET and NextGArch labs under the mentorship of Prof. Muhammad Shahbaz and Prof. Sonia Fahmy.
I completed my B.Engg and M.S. at NUST, Pakistan, and spent approximately four years in the industry. During this time, I started as a Malware Researcher and ultimately advanced to the role of Assistant Manager before transitioning to pursue my Ph.D.
My research focuses on systems and architectural innovations, with a particular emphasis on Security, Networks, and AI. Currently, I am working on developing NextGen architectural frameworks to enhance the scalability and efficiency of large-scale and distributed AI/ML systems.
