Venkatesh Chaturvedi attained his M.Sc. degree in Biochemistry in 2004, and Ph.D. degree in Biotechnology in 2011, from, Banaras Hindu University, Varanasi, Uttar Pradesh, India. Dr. Chaturvedi has more than twelve years of teaching experience in government/ private teaching institutions. Dr. Chaturvedi is currently working as Assistant Professor at School of Biotechnology, Institute of Science, Banaras Hindu University since 2019. Dr. Chaturvedi is a Group leader of Bioremediation and Environmental Biotechnology laboratory at School of Biotechnology, Banaras Hindu University. His area of expertise involves Environmental Biotechnology, Bioremediation, and Industrial Biotechnology. Pradeep Verma completed his PhD from Sardar Patel University Gujarat, India in 2002. In the same year, he was selected as a UNESCO fellow and joined the Czech Academy of Sciences Prague, Czech Republic. He later moved to Charles University, Prague to work as postdoctoral fellow. In 2004 he worked as a visiting scientist at UFZ Centre for Environmental Research, Halle, Germany. He was awarded a DFG fellowship that provided him with another opportunity to work as a postdoctoral fellow at Gottingen University, Germany. Later in 2007 he returned to India and joined Reliance Life Sciences, Mumbai, and worked extensively on biobutanol production, which attributed a few patents to his name. Maulin P. Shah is an active researcher and scientific writer in his field for over 20 years. He earned a B.Sc. degree (1999) in Microbiology from Gujarat University, Godhra (Gujarat), India. He also earned his Ph.D. degree (2005) in Environmental Microbiology from Sardar Patel University, Vallabh Vidyanagar (Gujarat), India. He is Chief Scientist & Head of the Industrial Wastewater Research Lab, Division of Applied and Environmental Microbiology Lab at Enviro Technology Ltd., Ankleshwar, Gujarat, India. His work focuses on the impact of industrial pollution on the microbial diversity of wastewater and genetically engineering high-impact microbes for the degradation of hazardous materials. His research interests include Biological Wastewater Treatment, Environmental Microbiology, Biodegradation, Bioremediation, & Phytoremediation of Environmental Pollutants from Industrial Wastewaters.
