International collaboration

Professor John Pote - Department F.-A. Forel for Environmental and Aquatic Science - Université de Genève, Geneva, Switzerland

This collaboration is in the field of waste management. Both parties are involved in research and supervsion of students' thesis students from Université de Kinsahsa and Université de Genève. As a result, several articles and thesis have been published.

Professor Gideon Odowu - Department of Chemistry - Federal University of Technology Akure (Futa), Ondo Sate, Nigeria

I am involved in the project titled: Microplastics and plastic-derived checmical contaminant in Africa: implication on human health and the loss of aquatic biodiversity. The project is funded by the Jennifer Ward Oppenheimer Foundation.
