About Me

I am a fourth year Computer Science PhD Candidate in the Usable Security and Privacy Lab at the George Washington University where I am fortunate to be advised by Adam Aviv. I am closely working with Yixin Zou and Elissa Redmiles for the final chapter of my PhD. My research focuses on human factors in digital security and privacy. I investigate how users, especially understudied groups, interact with, use, and/or misuse security and privacy tools, then design more usable and secure solutions. I received my Masters from Carnegie Mellon University and Bachelors from Strathmore University.
