I am an associate professor at the Computer Science department at the University of Arkansas at Little Rock. I received my PhD from Worcester Polytechnic Institute in 2010. I am currently leading the Information Assurance Research (IAR) Laboratory. My research interests include cloud computing and big data security, wireless networks and security, security and privacy in cyber-physical systems, and applied cryptography. For details please see my CV [pdf].
I am looking for self-motivated Ph.D students in areas of Cyber Security, Cloud Computing and Wireless Networking. Please send me your CV, transcripts, TOEFL and GRE scores via email. You can also stop by my office at EIT 566. Financial support will be available to qualified students.
