Assistant Professor of CE

Research:

Dr. Olukayode Jegede studies the effect of pollutants on terrestrial ecosystems using microarthropods and other soil-based invertebrates as bioindicators. His research evaluates the toxic effect of pesticides, metals, PFAS, plastics, nutrients, veterinary pharmaceuticals, and other potential toxicants relating to the agricultural industry (terrestrial and aquatic) from one-health perspectives.

  • M.Sc., Zoology, Obafemi Awolowo University, Nigeria, 2014

Specialties/Focus:

  • Toxicology
  • Environmental Risk Assessment

Teaching:

  • Cooperative extension
