Born in Benin City, Nigeria, Dr Godwin Osakpemwoya Samuel EKHAGUERE is a Professor of Mathematics at the University of Ibadan, Ibadan, Nigeria. His research activities are in the core areas of mathematical physics; algebras and partial algebras; and classical and noncommutative stochastic analysis including financial mathematics. He has made landmark contributions to these branches of mathematics, especially his: C*-algebraic characterization of the super selection sectors of the free electromagnetic field; proof, for the first time, of a central limit theorem in probability gage spaces over semi-finite W*-algebras of operators, including a noncommutative Levy-Khinchine representation for the Fourier transforms of limit probability gage spaces; pioneering and opening up of an entirely new field of mathematical research when he introduced quantum stochastic differential inclusions, and then studied the classes of Lipschitzian quantum stochastic differential inclusions, hypermaximal monotone quantum stochastic differential inclusions and quantum stochastic evolutions; introducing, for the first time, of a wide class of noncommutative semimartingale-driven stochastic integral/differential equations in seven different locally convex operator topologies and studying the existence and uniqueness of their solutions; and characterization of the completely positive maps on certain partial *-algebras; introduction and study of unbounded partial Hilbert algebras; his formulation and characterization of Dirichlet forms on partial *-algebras, and his study of the structure and representations of partial algebras. In global recognition of his seminal publications, Professor Ekhaguere has held several visiting scientist/professor positions in reputable research institutions around the world and won many highly competitive and prestigious scholarships / fellowships / sponsorships from diverse academic foundations / institutions, including the Associateship and Senior Associateship of the Abdus Salam International Centre for Theoretical Physics, Trieste, Italy, Fellowship of the Alexander von Humboldt Foundation, Bonn, Germany, as  well as Sponsorship of the Volkswagen-Stiftung, Sponsorship of the Deutsche Forschungstemeinschaft, Sponsorship of the Japanese Society for the Promotion of Science, Sponsorship of the Commemorative Association for the Japan World Exposition (1970), Sponsorship of the Swedish Agency for Research Cooperation with Developing Countries, Sponsorship of the Forschungsinstitut für Mathematik, Eidgenossische Technische Hochschule (ETH), Zürich, Switzerland, Staff Exchange Fellowship of the Association of African Universities, and Sponsorship of the London Mathematical Society. He has given many invited lectures in Nigeria and abroad. For example, he has already been invited this year 2013 to give one of the distinguished plenary lectures at the continental Pan-African Congress of Mathematicians, which brings together all mathematicians in Africa every four year, which is scheduled to hold in Abuja, Nigeria, in July 2013.   Professor Ekhaguere serves on the Editorial Boards of the following journals: Journal of the Nigerian Mathematical Society, Journal of the Nigerian Association of Mathematical Physics, Journal of the Mathematical Association of Nigeria, Journal of Science Research (Faculty of Science University of Ibadan)),  Afrika Matematika (Springer Verlag), and the South Pacific Journal of Pure & Applied Mathematics (University of Papua New Guinea). He also acts as a reviewer for several international journals of mathematics/mathematical physics, including: Abacus: Journal of the Mathematical Association of Nigeria, Journal of Science Research (Faculty of Science, University of Ibadan), Journal of the Nigerian Mathematical Society, Journal of the Nigerian Association of Mathematical Physics, Journal of Mathematical Analysis & Applications, Elsevier Publishers, USA, Journal of Mathematics & Mathematical Sciences, Hindawi Publishers, USA, Mediterranean Journal of Mathematics, Springer Publishers, Germany, Stochastic Analysis & Applications, Taylor & Francis Publishers, USA, Afrika Matematika, Springer Verlag, Acta Mathematica Sinica, Elsevier Publishers, USA. Professor Ekhaguere has served as an assessor of candidates for appointment/promotion to the grade of Associate Professor/Professor of Mathematics and as an external examiner at several universities in Nigeria and on the continent.  In addition to his Professorship at the University of Ibadan, Professor Ekhaguere is the Founder and President of the International Centre for Mathematical & Computer Sciences (ICMCS), Lagos (www.icmcs.org). An inspiring lecturer and mentor, he upholds the highest standard of mathematical research and training, as evidenced by the high quality of the MSc, MPhil and PhD graduates supervised by him.
