Brief career profile

Somsubhra Chakraborty, a Louisiana State University (USA) alumnus is presently the faculty member in the Agricultural and Food Engineering Department at the Indian Institute of Technology Kharagpur, India. He has worked as a Post-Doctoral Research Fellow at West Virginia University, USA. His research areas include portable proximal sensor-based soil and water characterization, digital soil mapping, mobile image-based soil analysis, and app development. Dr. Chakraborty has developed a patented methodology for combining multiple proximal soil sensors to improve the predictive accuracy relative to the individual technique in isolation on the analyte of interest (US patent US-2017-0122889-A1) titled “Portable Apparatus for Soil Chemical Characterization”. He has on-going collaborations with scientists from several countries including the USA, Canada, Romania, Brazil, China, and Morocco. He has received the Australia Awards Fellowship (2016) and Shastri Scholar Travel Subsidy Grant (2019-20). With more than 50 peer-reviewed publications in reputed international journals, Dr. Chakraborty has an h-index of 22 and i10 index of 37. He is an editorial board member of Geoderma (Elsevier), the global journal of soil science. He is currently supervising four Ph.D. students and leading several research projects.
