Dr. Joseph Kayefor Ebigwai

Senior Lecturer

Ebigwai Joseph Kayefor is a Senior Lecturer in Plant and Ecological Department in the faculty of Biological Sciences. He holds a PhD degree in Taxonomy and Systematic from the University of Port Harcourt.. He has lectured and mentored students across all strata of tertiary institutions in Nigeria to wit:  Delta State University, Abraka, Delta State Polytechnic, Ozoro and Delta State College of Physical Education, Mosogar. He teaches Taxonomy, Biodiversity, Environmental Pollution, Conservation and Ecological courses in undergraduate and post graduate levels. His research interest in addition to the aforementioned areas is developing periodicity for the authentication of plant species and mapping of threatened species in the Cross River National Park. He has published over 25 journal articles in learned journals, presented about 15 conference papers in Nigeria and abroad, has conducted over 50 technical studies in Environmental management, is on several government review panels on Environmental Impact Assessment, has graduated four post graduate students and supervised over 200 undergraduate students. He has several industry experiences in the oil and gas, construction and agro allied sectors for which he provide technical  and environmental services. He has organized several talks and sensitization campaigns on environmental management and on the impacts of poaching and uncontrolled logging in protected areas. He is a member of several professional bodies to wit; Botanical Society of Nigeria, Botanical Society of America, International Association of Plant Taxonomists, Palynological Association of Nigeria,  West African Association of Quaternary Palynologists and Nigerian Environmental Society. More recently he led the team on the approved  version of the Biodiversity  Action Plans for the Calabar Superhighway and Giant Cement Works Limited. He is the Senior Partner at Mifor Consult Nigeria Limited, and environmental  and geotechnical firm. He is  research oriented, self motivated and aspires to be a solution to global environmental and taxonomic challenges
