Mahendra Rai is an internationally recognized scholar with extensive contributions to microbial biotechnology and nanobiotechnology research, particularly in the green synthesis of metal nanoparticles using fungi and their application as nano‑antimicrobials. His work is highly interdisciplinary, bridging microbiology, biotechnology, and nanoscience, and he is an active member of several scientific societies. He has received multiple national and international distinctions, including the Father T.A. Mathias Award from the All-India Association for Christian Higher Education and the Medini Award from the Government of India. Professor Rai has also held numerous visiting scientist and visiting professor positions across Europe, South America, and Asia, contributing to long‑standing research collaborations in countries such as Brazil, Argentina, Hungary, Switzerland, Italy, Germany, and the United States. His sustained academic impact is reflected in his inclusion among the global top 2% of scientists in nanoscience and nanotechnology, and recognition as one of India’s leading researchers in biology and biochemistry, including a Biology and Biochemistry India Leader Award from Research.com. Dr. Avinash P. Ingle is currently working as a Research Scientist (Ramanujan Fellow) at the Biotechnology Centre, Department of Agricultural Botany, at Dr. Panjabrao Deshmukh Agricultural University, in Maharashtra, India. He completed his doctoral degree at SGB Amravati University, working as a Research Scientist at the same institution from 2013 to 2016, before being awarded a Postdoctoral Fellowship (FAPESP) at the Department of Biotechnology, Engineering School of Lorena, University of Sao Paulo, Brazil, for three years. Dr. Ingle has edited several books with various international publishers, 65 book chapters, and over 90 research publications in international, peer-reviewed journals. His research interests include nanobiotechnology, biofuel technology, and sustainable agriculture.
