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 ).

Work Experience

Research Intern
Tencent America, Bellevue, Washington, United States
May. 2021 - Aug. 2021
Implemented a neural-network-based fast diffuse room impulse response generator (FAST-RIR) for generating room impulse responses (RIRs) for a given acoustic environment.

Engineer
Wave Computing, Colombo, Sri Lanka
Feb. 2018 - Jul. 2019
Developed machine learning applications for Wave Computing’s Dataflow Processing Unit (DPU) Architecture using Wave Flow Graph (WFG), a data flow description language developed by Wave Computing. Compiled and simulated the designs in Wave Computing’s complete EDA toolchain. Debugged and proposed suggestions to improve the toolchain and the architecture.

Research Intern
HESL Lab, Nanyang Technological University, Singapore
Aug. 2016 - Dec. 2016
Successfully completed a project titled “Low complexity techniques for Vehicle Localization and Tracking" under the guidance of Dr. Lam Siew Kei .
