Dr. Chakraborty's research interests lie in proximal soil sensors in combination with data mining and machine learning, with a focus on developing scalable algorithms for rapidly and non-invasively predicting soil properties. In particular, he has worked on developing methods for sensors like portable XRF, diffuse reflectance spectroscopy, smartphone-based soil sensing, Nix color sensor, digital soil mapping, as well as techniques for dealing with real-time soil characterization. He has published over 100 research articles in various international journals and conferences, and his work has been cited over 3,700 times. He has received several awards and honors for his contributions to the field of soil science, including the Australia awards fellowship and SPESS garden scholarship (USA). In addition to his research, Chakraborty is also actively involved in teaching and mentoring students at IIT Kharagpur. He has supervised several Ph.D. and M. Tech. students and has also been involved in the development of several online courses on soil science.
