I am an associate professor in the Knight Foundation School of Computing and
Information Sciences at FIU in Miami. I direct the CaSPR lab,
where we address complex societal challenges that include disinformation and
censorship. We build systems, design and conduct user studies, leverage cryptography and AI to study online fraud, fake news, cyberabuse and censorship, and develop defenses.
CaSPR lab opening: I am looking for smart and motivated Ph.D. students. Send me an e-mail if interested.
