About Me

Currently, I am working as a Member of Research Staff at Palo Alto Research Center (PARC). I am part of the Complex Systems Analytics team, within the Intelligence Systems Lab at PARC. My research interest lies at the intersection of machine learning, scientific visualization and explainable AI.

Prior to joining PARC, I was a Postdoctoral Researcher at the Information Sciences Group of Los Alamos National Laboratory (LANL). I graduated with a Ph.D. and an M.S. from the Department of Computer Science & Engineering of The Ohio State University in 2019. At Ohio State, I was a member of the GRAphics and VIsualization sTudY (GRAVITY) research group led by my advisor, Dr. Han-Wei Shen. I completed my Bachelor’s in Computer Science & Engineering from National Institute of Technology, Durgapur, West Bengal (India) in 2011.
