Research

I direct the ECE Computer Security Research Group (CSRG). My research area is a mix of fundamental and applied aspects of information security. I am currently interested in:

(1) Foundational aspects of authorization in information systems, malware detection using machine learning, secure and privacy-enhanced machine learning.

(2) Application of results from (1) in domains such as cloud computing, internet of things, and social networking. These domains also inform my research in (1).

See the projects that I work on below.

See my publications. Also, my Google Scholar Public Profile.

I am also a Research Faculty in the Institute for Cyber Security (ICS) at UTSA.
