BioSketch

I am 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 of Prof. Rahul Shah. My Bachelor degree is in EEE from National Institute of Technology Calicut, India.

Research

My research interests are in the areas of algorithms and data structures. In addition to fundamental problems, I have worked on problems that have direct applications in app lied fields, such as computational biology, information retrieval, and computational geometry. During the course of this research, I have successfully collaborated nationally and internationally, and published articles in journals like Journal of ACM, Algorithemica, Journal of Computational Biology, etc and peer-reviewed conferences like SODA, RECOMB, Super Computing (SC), SIGIR, Data Comp ression, etc. Currently I am working on several problems in the following areas:
