About Me

I am an Assistant Professor in the Department of Computer Science at New Jersey Institute of Technology. Before that, I got a Ph.D. in Computer Science in May 2019 from UMD jointly advised by Dr. John Dickerson and Dr. Aravind Srinivasan, and another Ph.D. in Operations Research in Aug. 2012 from ISU under the supervision of Dr. Lizhi Wang.

I have been fortunate to be supported by several Fellowships and Awards including an F. Wendell Miller Fellowship (2009-2012, ISU), a Research Excellence Award (2013, ISU), an Ann G. Wylie Dissertation Fellowship (2018-2019, UMD), an Outstanding Graduate Assistant Award (2018, UMD), and a Larry S. Davis Doctoral Dissertation Award (2019, UMD).
