Dr Nipen Nayak

Dr. Nipen Nayak completed his foundational schooling with an HSLC from Seven Sister English Academy, Khowang in 2007, followed by his Higher Secondary (HS) education at Moran College in 2009. Continuing his academic journey at Moran College under Dibrugarh University, he graduated with a Bachelor of Science (B.Sc.) degree in 2012. Driven by a passion for biological sciences, he went on to earn his Master’s degree in Life Sciences from the Department of Life Sciences, Dibrugarh University in 2014. Dr. Nayak was awarded his Ph.D. in 2022 for his doctoral thesis titled, "Studies on feeding and reproductive biology of Rainbow snakehead Channa bleheri with special reference to its breeding and captive breeding," establishing his expertise in ichthyology and aquaculture conservation.
