About

I am an associate professor and the graduate program director in the Knight Foundation School of Computing and Information Sciences at FIU in Miami. I direct the CaSPR lab, where we build secure and private solutions for distributed systems. We leverage diverse tools and techniques (e.g., machine learning, applied cryptography, user studies) to investigate problems that include fraud and abuse detection in online systems, mobile authentication and censorship resistance.

Open positions: The CaSPR lab is looking for talented and motivated Ph.D. students. If you are interested and would like to apply, please read this first and follow the instructions.
