Dr. Pasiyappazham Ramasamy is an accomplished Marine biologist and biotechnologist with extensive expertise in marine bioresources, biopolymers, and translational life sciences. He currently serves as Associate Professor (Research) and heads the Marine Biopolymer Research Lab at the Centre for Marine and Aquatic Research, Saveetha Institute of Medical and Technical Sciences (SIMATS), Chennai, India. His interdisciplinary research spans marine biology, microbiology, biotechnology, pharmacology, and environmental sciences, with a strong emphasis on the valorization of marine-derived biomaterials for biomedical, environmental, and industrial applications. He earned his Ph.D. in Marine Biology and Oceanography from Annamalai University, where his doctoral research investigated the in vitro and in vivo antioxidant properties of chitosan and the wound-healing potential of collagen–chitosan films derived from cephalopods. He has held several prestigious research and academic positions in India and abroad. Notably, he completed an international postdoctoral fellowship at Xiamen University, China, focusing on quorum-sensing inhibitors for controlling microbially influenced corrosion. He is a recipient of the UGC–Dr. D.S. Kothari Postdoctoral Fellowship and the Indian National Science Academy (INSA) Visiting Scientist Award. In addition to his research roles, he has served as Assistant Professor and Head of the Department at institutions including PRIST Deemed University, National College (Autonomous), Tiruchirappalli, and Mass College of Arts and Science. He has published over 120 articles in international peer-reviewed journals, holds multiple patents, and has an H-index of 26. His contributions have been recognized through several honors, including the Best Researcher Award (2025) and AGAR Research Excellence Award (2024). His ongoing research focuses on marine biowaste valorization, functional biopolymer development, and sustainable, eco-friendly innovations aligned with global sustainability goals.
