Hello! Welcome to my website! I am currently a Researcher in the Geospatial Artificial Intelligence (GeoAI) group at Oak Ridge National Laboratory (ORNL).
At ORNL, I work on developing scalable machine learning driven geospatial image analytics workflows for humanitarian applications. I earned my Doctoral Degree in Geoinformatics, under the supervision of Prof. Surya Durbha in the GeoComputational Systems Lab at Indian Institute of Technology Bombay. My research interests include Deep Learning for Computer Vision, Large-Scale Satellite Image Processing, Remote Sensing and GIS, High Performance Computing, Geospatial Knowledge Representation and Reasoning, Natural Language Processing, and Internet Of Things. My doctoral research explored the areas of Geospatial Semantics and Deep Learning for Satellite Image Processing, towards leveraging Knowledge Graphs for enhanced Scene Understanding of Remote Sensing Scenes.
As a part of the Google Summer of Earth Engine 2019 Research Program, I worked on "Machine Learning based Mapping of Croplands with Google Earth Engine for Identifying Human-Wildlife Conflict Locations" with Centre for Wildlife Studies. I have been a two-time Google Summer of Code student for the organizations - Cesium in 2015, where I contributed to the NASA's Global Imagery Browse Services (GIBS) by processing and visualizing 3-dimensional LiDAR data from the CALIPSO satellite; and Liquid Galaxy in 2016, where I worked on enabling Cesium for a panoramic experience on the Liquid Galaxy hardware. Prior to joining IIT Bombay as a graduate student for my Masters and PhD, I completed my Bachelors in Computer Engineering from University of Mumbai.
I am an open source enthusiast and have been a code contributor to Mozilla Firefox. When not at my terminal or engrossed in a sci-fi novel, I enjoy travelling places, capturing and captioning the world through my camera.
