He has led the projects on applying assisted reproduction technology, developing progesterone impregnated device, developing techniques of improving fertility of buffaloes during low breeding season as well as enhancing overall reproductive efficiency in livestock species, understanding the role of some of the endogenous steroids on reproductive and metabolic behavior, particularly on the effects of estrogen hormone on calcium metabolism pathway, of dairy animals and so on.

Prof. Devkota has authored/co-authored more than 45 research papers in internationally recognized SCI journals, more than 25 in the past 7 years, have more than 60 proceeding/abstract publications and a large number of publications in national journals and bulletin over the years.
