In 1980, he joined the Institute of Technology, Benin (later renamed the University of Benin), where he served as the founding dean of the Faculty of Physical Sciences and director of the Centre for Mathematical Sciences. Additionally, he held the position of vice-chancellor from 1985 to 1986.[5]
He contributed as a visiting professor to various institutions, including the University of Lagos, University of Jos, University of Port Harcourt, University of Ilorin, University of Nigeria, Nsukka, University of Cape Coast (Ghana), University of Khartoum (Sudan), and the University of Waterloo, Canada.[5]
He published over 100 mathematics-related papers in international journals,[5] served as the editor-in-chief for Afrika Mathematika and Journal of the Nigerian Mathematical Society,[5] and chaired the board of Federal Polytechnic, Idah.[9]
