Research Interests:

Dr. Ejidike Peter received his Ph.D. (2016) from the University of Fort Hare, South Africa, where is researched the synthesis of metal complexes containing organic ligands like Schiff bases and their applications. He is a Senior Lecturer at the Department of Chemistry, Anchor University, Lagos, Nigeria.

His interests activities revolve around the development of pharmaceutically/ biologically active Schiff base ligands and their metal compounds as chemotherapeutic agents, analytical/ environmental tools, electrochemistry, computational studies, and applicability of metal oxides nanoparticles from Schiff-base metal complexes by thermo-decomposition methods for bio-catalytic routes, industrial and biological applications.

Likewise, the isolation of bio-active constituents from medicinal plants for biological applications and synthesis of metal nanomaterials via green synthesis.
