I am an associate professor of Electrical & Computer Engineering at Stevens Institute of Technology. Before I joined Stevens in 2017, I had been an associate professor in Computer Science at the University of Arkansas at Little Rock, where I also served as the interim chair of the CS department and the director of the Computational Research Center of the university. I received my PhD from Worcester Polytechnic Institute in 2010. I am currently leading the Information Assurance Research (IAR) Laboratory. My research interests include big data security and privacy, security in emerging smart systems, wireless networking and security, and applied cryptography.

I am always looking for self-motivated Ph.D. students to join my research group. Candidates with solid mathematical, analytical, or system implementation background in related areas are encouraged to apply. You can send me your CV, transcripts, TOEFL and GRE scores via email, or simply stop by my office at Burchard 412.

Visiting scholars and students with shared research interests are also welcome to contact me.
