Avik Bhattacharya received the integrated M.Sc. degree in mathematics from the Indian Institute of Technology, Kharagpur, India, in 2000 and the Ph.D. degree in remote sensing image processing and analysis from Tlcom ParisTech, Paris, France, and the Ariana Research Group, Institut National de Recherche en Informatique et en Automatique (INRIA), Sophia Antipolis, Nice, France, in 2007.[2]
Bhattacharya has pursued postdoctoral research at the Canada Centre for Mapping and Earth Observation (CCMEO) (formerly, Canada Centre for Remote Sensing (CCRS), Natural Resources Canada, Ottawa, Canada) from 2008 to 2011. He was awarded the Visiting Fellowship in Canadian Government Laboratories (VF) by the Natural Sciences and Engineering Research Council of Canada (NSERC). During his post-doctoral tenure at CCRS, he worked extensively on polarimetric decomposition techniques, especially in the development of the methodology and the application of the multi-resolution target scattering vector model for characterizing scattering mechanisms from urban areas.[2]
Professional Career
Bhattacharya joined the Centre of Studies in Resources Engineering (CSRE), Indian Institute of Technology Bombay (IITB), India in 2011 as an Assistant Professor. He currently serves as an Associate Professor. At CSRE he offers courses on Principles of Remote Sensing, Data Analysis Methods for Geospatial Applications, Microwave Remote Sensing, and Advanced Concepts in Polarimetric SAR Image Analysis. He leads the Microwave Remote Sensing Lab at CSRE, IITB[1].[4]. He is involved in various research related to the developments of scattering power decomposition models and factorization framework using SAR data. He is extensively involved in the application of his research to many different aspects of Earth observation. Predominantly, understanding the physics of scattering from targets and extraction of relevant information from SAR data using novel mathematical and statistical models plays a vital role in his research endeavours[5]. He is also actively involved in research related to machine learning with a particular interest in deep learning using SAR data for ecosystem studies[6]
He supervises research on these topics within the frameworks of many national and international projects. Bhattacharya is the Principal and Co-principal Investigator of numerous projects sponsored by the Department of Science and Technology (DST), Government of India, Defense Research and Development Organization (DRDO), Government of India, and Indian Space Research Organization (ISRO)[2], GEOGLAM-JECAM SAR Inter-Comparison Experiment[7]. He has authored several scientific publications in refereed international journals and conference proceedings[2]. He is invited to present several lectures in reputed universities and institutions in India and abroad.
Bhattacharya is the Editor-in-Chief of the IEEE Geoscience and Remote Sensing Letters (GRSL)[8][9]. He is the founding chairperson of the IEEE Geoscience and Remote Sensing Society (GRSS) chapter, Bombay section, India[8]. He was a guest editor of the special issue on “Applied Earth Observations and Remote Sensing in India” in IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing (JSTARS), 2017[10].
