Prof. Rosita Ijeoma Okechukwu


B.Sc., PDGE, M.Sc., PhD


Rosita has sound academic qualification and competence. She studied Botany at Imo State University. She proceeded to the University of Jos, where she did her Masters degree in Applied Microbiology and Plant Pathology. From the University of Jos to the Federal University of Technology Owerri where her academic pursuit finally landed her to a PhD in Environmental Health Biology. Her research interests are on Environmental health biology, investigation of phytochemicals in herbal remedies for skin diseases in the Tropics, different types of Alternative Energy, Environmental Waste Management, and investigating available non-feed stock sources of biogas, biodiesel etc.

Rosita has the vast administrative experience been the Head of Department of Biology (2012-2016) where she facilitated the development of the Undergraduate and Postgraduate degree programmes in Biology of the University, which had since resulted in the establishment of a full-fledged and flourishing Department of Biology. Also, she is the chairperson and member of various University Committee including the School of Science Seminar Committee, Student Academic Advisorship, University Senate Committee on Student Violence, School Research Committee, Member, University Environmental Waste Management Committee, among others.

Rosita started lecturing at ABU/FCE Kano as an Assistant lecturer in the Department of Biology in 1996. She later secured a tenure appointment with the Federal University of Technology, Owerri in 2003 as a Lecturer II Staff. Through a high level of commitment to official duties, hard work and scoring more points than required, Rosita was promoted to the rank of Professor in October 2015. She has over fifty publications in referred journals spread across the world: Africa, Europe, Asia, North America. Also, some productive works, 3 books in main discipline, 6 chapters in referred books to her credit. She has attended many conferences, workshop and training spread across the globe.
