I am a third-year PhD student in Electrical and Computer Engineering at the University of Maryland-College Park and a member of the GAMMA Lab supervised by Professor Dinesh Manocha. At present, my research is in acoustic simulations and far-field speech augmentation. My previous research involves Computer Vision (Video Summarization, Forensic Detection ) and Speech Processing ( Automatic Speech Recognition ).
