Dr. Dileep Kumar Gupta received his doctoral degree from the Department of Physics, Indian Institute of Technology (Banaras Hindu University), Varanasi, India. Dr. Gupta received several reputed awards including the UGC-NET, GATE, UGC research fellowship, and DST international travel support. He has published 50+ research articles in different peer-reviewed journals/conference proceedings/book chapters. He is a reviewer of different publishers including Elsevier, Springer, Taylor & Franchise IEEE, and SPIE. He also edited a Special Issue as a guest editor of remote sensing (MPDI). He is an expert in the parametrization of tau omega algorithms for the retrieval of accurate surface soil moisture at the regional scale using SMAP brightness temperature; the development of the high-resolution soil moisture algorithm using disaggregation techniques; monostatic and bistatic radar measurement for vegetation and soil moisture applications; microwave active and passive remote sensing for soil moisture retrieval; modeling of machine learning algorithms for remote sensing; optical/IR remote sensing for crop classification; and land use/land cover and vegetation indices retrievals.
