I am currently pursuing PhD with Computer Engineering, University of New Mexico. I am being advised by Dr. Marios Pattichis. My areas of emphasis include Image analysis, Video analysis (Human activity recognition), Video compression (HEVC, VP9) and Video delivery (MPEG DASH). In addition I have good experience in Web development, Statistical analysis, and Machine learning. I received my Bachelors degree in ECE (Electrical and Computer Engineering) from VIT (Vellore Institute of Technology). Before joining IVPCL, I have two years industrial experience in Video Compression.

Drastic focuses on developing adaptive video processing system that can respond to changes in content, environment and needs of user. This adaptability is demonstrated using reconfigurable hardware and software specific to HEVC (High Efficiency Video Coding). In this current iteration, I am involved in developeing a codec agnostic frame work that delivers optimal video stream over HTTP using state of the art adaptive delivery mechanism.


AOLME project implements integrated curriculum for teaching computing foundations based on middle-school mathematics. This involves collection of Tera Bytes of videos to develop learning models that help in understanding how students acquire comptuing knowledge. I am involved in developing video analysis methods (human activity recognition, screen activity recognition) that aid in developing learning models.


Images with region of interest (roi) are most common output of forecasting systems which study and map evolution of astronomical events. The models built for such natural events tend to have multiple random free parameters resulting in multiple forecasting maps. Due to inherent randomness, it is impossible to identify optimal free parameters, requiring dynamic classification of models as good or bad. In this paper we attempt to solve one such classification problem by carefully designing and employing protocols to subjectively classify models as good or bad. Upon subjective classification, an automated framework is created to do the same.
