Dr. Prakash Chauhan obtained his postgraduate degree in Applied Geophysics from Indian Institute of Technology (IIT), Roorkee and Ph. D. in Physics from Gujarat University, Ahmedabad. Prior to joining Indian Institute of Remote Sensing (IIRS), Dehradun, he was the Group Director at the Space Applications Centre, (ISRO), and Ahmedabad since 2014. He joined Indian Space Research Organisation (ISRO) in 1991 as scientist and since then working for the applications of remote sensing technology for natural resources management for ocean and land resources. He initiated research activities for planetary remote sensing at Space Applications Centre to study solar system objects mainly Earth’s Moon and Mars, through Indian planetary missions.
His major achievements are in the area of earth observation applications including development of algorithms for ocean colour parameter retrieval, marine living resource assessment, aerosol remote sensing for space based air quality monitoring, river and reservoir water level estimation using space borne altimeters and coastal zone management. He has done lead work in using the hyperspectral data for lunar surface composition mapping using HySI and Moon Mineralogical Mapper (M3) instruments of Chandrayaan-1. He has been the Principal Investigator for Infrared Imaging spectrometer (IIRS) instrument on-board Chandrayaan-2 mission. He also led a team of scientists for scientific analysis of data from Mars Orbiter Mission (MOM) instruments. He has published more than 100 research papers in both National and International Journals.
He is an executive member of International Ocean Colour Co-ordination Group (IOCCG) and representing ISRO. He has also represented ISRO at CEOS as Co-Chair for Ocean Colour Virtual Constellation (OCR-VC). Currently he is a member of the prestigious NASA-ISRO Planetary Science working group. He has been awarded prestigious Prof. P.R. Pisharoty memorial award for the year 2004 by Indian Society of Remote Sensing, Hari Om Ashram Prerit Dr. Vikram Sarabhai Research Award by Physical Research Laboratory (PRL), Ahmedabad for 2009, ISRO merit award by Indian Space Research Organisation in 2010 and Satish Dhawan award by ISRS, Dehradun for 2016.
