I am an assistant professor in the School of Computing and Information Sciences at FIU in Miami.
My research interests are in privacy and security issues in online (geo)social networks
(e.g., fake review detection, private location-centric aggregates, location verification),
caching in content distribution networks of video on demand providers, private data and
computation outsourcing, electronic payments.
