Ajoy Kumar Saha joined the Sylhet Agricultural University as Lecturer in the Department of Irrigation and Water Management, Faculty of Agricultural Engineering & Technology, Sylhet Agricultural University, Sylhet-3100, Bangladesh, on 1 January 2013. Since 1 January 2015, he is working as Assistant Professor. In fall 2019, he started his Ph.D. program as a Graduate Research Assistant (GRA) in the Department of Agricultural and Biosystems Engineering, South Dakota State University, SD, USA. Currently, he is investigating the impact of cover crops on soil health practices and observing the nutrient and water dynamics through the soil profile in the root zone. In 2014, he got a VLIR-OUS scholarship to pursue a master as IUPWARE (Inter-University Program of Water Resources Engineering) student from KU Leuven and VUB, Belgium. In 2016, he obtained a Master of Water Resources Engineering from KU, Leuven (and VUB, Brussels), Belgium, with great distinction results. During this master's, he had also completed a thesis work on ''Multi-model approach to quantify the conceptual model uncertainties in groundwater simulation in Bangladesh'' with professor dr. Ir. Marijke Hysmuns. Moreover, I studied some of the different Modelling courses (like MODFLOW, HYDRUS, HEC-HMS, AquaCrop, etc.) and basic of programming languages (such as R, R-Studio, MatLab, etc.) for numerical modeling of the Water Resources System. I have studied GIS, Remote Sensing (use ArcGIS, ILWIS software), Advanced Mathematics and Statistics, etc. for formulating water resources systems. He completed a bachelor's in Agricultural Engineering in 2008 and a master's in Irrigation and water management in 2010 from Bangladesh Agricultural University, Bangladesh. He started his research career as an undergraduate student focusing on wastewater treatment for agricultural use by low-cost filter materials in 2007. Later, I have identified the sensitive growth stage of wheat to irrigation water salinity as an MS student under the supervision of Professor Dr. M A Mojid. He has a keen interest in crop and irrigation water modeling and conservation agriculture. Besides this, he has a keen interest in climate change impact assessment and applying remote sensing for appropriate precision agriculture to save water.
