Dr. Akhileshwar Kumar Srivastava works as a Research Associate (ICMR) at CSIR-Central Food Technological Research Institute, Mysore, India. In his 11 years of research, he has published more than 18 research articles in reputed international journals, along with 4 books and 11 book chapters. His research specialization is primarily in the area of pharmacognosy with genetics, metabolomics, bioinformatics, and molecular biology associated with targeting virulent factors of diseases. In addition, he has studied at Augusta University (formerly, Georgia Regents University) in Augusta, GA, USA, on a J-1 Exchange Scholar Visa and at Ben-Gurion University, Israel. He is also a life member fellow in the Indian Science Congress and the Agriculture, Nutrition and Health Academy, UK. Dr. Vinod Kumar Kannaujiya is an assistant professor in the Department of Botany, MMV, Banaras Hindu University, India. He earned his MSc and PhD degrees in Botany from the Centre of Advanced Study in Botany, Banaras Hindu University. He has been working on the ultraviolet stress response of cyanobacteria including value-added enzymes, proteins, pigments, and natural compounds. He has been awarded with prestigious fellowships from the Council of Scientific and Industrial Research, New Delhi, India. He has also been awarded the Dr. D.S. Kothari Post-Doctoral Fellowship from University Grant Commission, New Delhi, India, and he has received a UGC-Startup project grant from UGC, New Delhi, India. Dr. Kannaujiya is a life member fellow of the Indian Photobiology Society. Thus far, Dr. Kannaujiya has published over 49 original research papers, reviews, and book chapters. Dr. Rajesh Kumar Singh is currently working as a Research Associate in Banaras Hindu University. His research focus is pharmacognosy, reverse pharmacology, drug design and discovery, extraction & isolation of natural products, cell culture, and handling of different rodents. He has published several research articles in reputable journals over the course of his career. At present, he is involved in developing an Indian origin cell line and screening drugs of natural origin for the treatment of gallbladder cancer. Dr. Divya Singh is presently working as a scientist in Central Sericultural Research and Training Institute, Mysore, India. Her research specialization is primarily in genetics, proteomics, metabolomics, toxicology, bioinformatics, and molecular biological evaluation in various in vivo and in vitro plant models to elucidate the physiological changes and evaluate the DNA damage potency. She has published morethan 10 research articles including book chapters. In addition, she is also a life member fellow of Indian Science Congress.
