I have organized the String Algorithms in Bioinformatics Workshop (StringBio), 2018 at UCF Campus (click here for details)

BioSketch: I am currently an Assistant Professor in the department of computer science at University of Central Florida. Before joining UCF, I have worked as a Research Scientist/PostDoc in the School of Computational Science and Engineering, Georgia Institute o f Technology, Atlanta with Prof. Srinivas Aluru and in the Cheriton School of Computer Science, University of Waterloo, Canada with Prof. J. Ian Munro. My Ph.D. is in Computer Science from Louisiana State University (Spring 2014), supervised by Prof. Rahul Shah. My Bachelor degree is in EEE from National Institute of Technology Calicut, India.

Research: I work in the areas of String Algorithms and Bioinformatics, Succinct/Compressed Data Structures and High Performance Computing. My research is supported in part by the US National Science Foundation (NSF) under CCF-1703489 and startup funds from UCF. 

Selected Publications: The complete list of my publications can be found in DBLP or Google Scholar.
