Professor Sanjay Kumar Bhardwaj is a distinguished zoologist with over 35 years of research experience, recognized for his pioneering work in photoperiodism, seasonal breeding, light color, and intensity effects in birds. Currently serving as a Professor of Zoology, he has contributed extensively to avian chronobiology and environmental physiology, with 89 research papers, multiple book articles, and proceedings. He has supervised numerous M.Phil. scholars and Ph.D. researchers, led more than 10 major research projects, and secured substantial funding from DBT, SERB, UGC, CSIR, DST, and State Government of U.P. His international exposure includes prestigious INSA Exchange Fellowships, and he has represented India at major global conferences such as the International Ornithological Congress and International Chronobiology meetings. Recognized with honors like the FAEB Fellowship, Research Excellence Award, Rashtriya Gaurav Award, and Lifetime Achievement Award, he has also organized major scientific symposia and workshops at national and international levels. His research continues to advance understanding of avian physiology, biological rhythms, cognition under light pollution, and environmental influences on animal biology.
