Bio:
I am an Assistant Professor in the Department of Computer Science end Engineering at Indian Institute of Technology Kharagpur. Before joining IIT Kharagpur, I spent beautiful 2½ years as a postdoc at
INRIA in the
MOSAIC team working with
Christophe Godin.
Before that, I was a visiting scientist during the period Dec'18-Jan'19
at CVPR Unit, Indian Statistical Institute Kolkata,
hosted by Ujjwal Bhattacharya.
Previously I was a postdoc for about an year at
KTH Royal Institute of Technology
in the Lagergren lab. I did my PhD in October 2017 in Computer Science from
University of Western Ontario where I was advised by
John Barron. I did my bachelors in Physics (Hons.) and masters in Computer Science & Engineering from
University of Calcutta.
Research Interests: I am interested in 3D computer vision and geometry processing in general. I am fascinated about problems like multi/single view 3D reconstruction, point cloud registration, segmentation, and shape analysis problems for different application areas. These days I am focusing on problems like correspondence estimation between deformable and occluded objects, object detection and registration in cluttered scene, part segmentation, volumetric reconstruction, and related problems. Alongside, I have been (& still) working in the interdisciplinary area on agricultural robotics and plant phenomics applications of computer vision. This area is an intersection of computer vision, machine learning, computational biology and agricultural automation. My long term goal is to develop light-weight, low-cost and robust computer vision based systems targeted for developing farms to assist in smart agricultural applications (e.g. organ tracking, disease detection, plant monitoring, etc).

Non-academic interests: I am passionate about high altitude mountaineering. I have done Basic Mountaineering Course (BMC) from Nehru Institute of Mountaineering (NIM), Uttarkashi and Advance Mountaineering Course (AMC) from Atal Bihari Vajpayee Institute of Mountaineering and Allied Sports (ABVIMAS), Manali, both with "A" grade. I actively pursue high altitude mountaineering expeditions.
