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 primarily interested in interdisciplinary research on agricultural robotics and plant phenomics applications of computer vision. Broadly I work in the 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). I am also interested in (data driven) geometry modelling of plants for computer graphics applications and botanical simulation studies. In general, I am fascinated about computer vision problems like point cloud registration, segmentation and shape analysis problems for different application areas as well.
- Currently I have an open project position in a DST SERB project "3D Reconstruction of Deformable Plants for Smart Farming and Remote Sensing Applications". The position is full time and the duration can be > 1 year depending on the performance. If you are interested, please contact me (deadline is 12th January 2023).
