About the Lecturer I
Mr. Lakhnarayan Bhagarathi is a Lecturer at the Institute for Marine and Riverine Ecologies and Economies (IMAREE), under the Department of Education and Training at the University of Guyana, and a Doctor of Philosophy (Ph.D.) candidate in Biodiversity. His current doctoral research explores insect pollinators within Guyana’s mangrove ecosystems, contributing to the scientific understanding of Guyana’s rich biodiversity of entomofauna in coastal environments. He holds a Master Degree in Disaster Risk Management and Climate Governance, a Master of Science in Forest Biology, a Post Graduate Diploma in Science Education, and a Bachelor of Science in Biology.
Mr. Bhagarathi's academic interests span multiple disciplines, including marine sciences, coastal ecology, biodiversity, entomology, mangroves, climate change, microbial sciences, zoology, botany, evolutionary biology, applied biology, biochemistry, conservation, science education, and sustainable agriculture. His research portfolio includes peer-reviewed journal articles, reviews, and book chapters with many citations, reflecting a commitment to advancing knowledge across scientific domains. He actively participates in collaborative research projects, peer reviews, and academic conferences at both national and international levels. Mr. Bhagarathi teaches a diverse collection of undergraduate courses, including capstone research project, marine biology, animal biology, microbiology, genetics, evolution, biotechnology, genomics, ecology, cell biology, molecular biology, and laboratory and field biology.
Mr. Bhagarathi also supports student research, emphasizing ethical practices and scientific integrity. Outside the classroom, he volunteers with environmental organizations and advocates for biodiversity conservation and sustainable development. Through his academic and outreach efforts, he contributes meaningfully to science education and environmental stewardship in Guyana and beyond.
