Dr. Veer Singh is currently working as Young Scientist (DHR) at the Department of Biochemistry, Rajendra Memorial Research Institute of Medical Sciences, Patna, India. He got PhD from the Indian Institute of Technology (Banaras Hindu University), Varanasi. He has more than 40 publications and his area of work involved Environmental contamination & toxicity, the role of drinking water heavy metals contamination in visceral leishmaniasis (VL) & post-kala-azar dermal leishmaniasis (PKDL) development.Dr. Ashish Kumar is currently working as Scientist-C and Head of Department at the Department of Biochemistry, Rajendra Memorial Research Institute of Medical Sciences, and Patna, India. He has published more than 40 publications in International/national journals. He has received several awards and received several funding (sponsored projects) from many national and international agencies. Currently, 4 doctoral and 2 postdoctoral students are working under the supervision of Dr. Ashish Kumar. Dr. Kumar is working in the interdisciplinary area of life science. His work is mainly focused on visceral leishmaniasis (VL) and post kala-azar dermal leishmaniasis (PKDL). He is also working on VL and PKDL diagnosis, treatment and environmental impacts on disease development.
