I am a Professor at the Department of Computer Science at the University of Alabama at Birmingham. I lead the SECuRE and Trustworthy Computing Lab (SECRETLab). I am also the founder of Shikkhok.com — an award-winning free education platform in Bengali language, and the co-ordinator of the BanglaBraille project, aimed at creating educational material for visually impaired children in South Asia.

I am a winner of the NSF CAREER Award for my research on trustworthy cloud computing.

In the past, I was an NSF Computing Innovation Fellow and Assistant Research Scientist at the Dept. of Computer Science, Johns Hopkins University. My research was supported by the 2009 NSF/CRA Computing Innovation Postdoctoral Fellowship. At Hopkins, I was a member of the Hopkins Storage Systems Lab and collaborated with Prof. Randal Burns.

I received my Ph.D. in Computer Science in October 2009, from University of Illinois at Urbana-Champaign. My advisor was Prof. Marianne Winslett. I was also co-advised by Prof. Radu Sion of SUNY-StonyBrook.

Research Interests

I am primarily interested in Computer Security in general, and Cloud Computing security, Secure Provenance, Trustworthy Databases, and Digital Forensics. I also introduced the notion of digital data waste – an area where my research has been covered by MIT Technology Review, cNET, and other media outlets.

My research is funded by a 2014 NSF CAREER Award from the National Science Foundation, grants from the Department of Homeland Security, the Office of Naval Research, a 2012 Google Faculty Research Award, and a 2012 Amazon Research Grant. In addition, I am a recipient of the 2013 Google RISE Award, 2013 the Best of Blogs and Online Activism Award for Innovation, and the 2013 Information Society Innovation Fund Award — all for my Shikkhok.com online education platform for South Asian children.
