For many years, Dr. Banyaga has been involved in Higher Education and Research in Africa. He is collaborating with the Institute of Mathematics and Physical Sciences in Benin ( IMSP). He is a member of the International Scientific Advisory board of IMSP. He is an editor of Africa Matematika. He is also a member of the United States National Committee for Mathematics ( of National Research Council, and the US National Academy of Sciences).


Current Interests: locally conformal symplectic geometry and Bott-Morse-Floer homology, Contact Geometry and Topology. Most of past research focused on the structure of classical diffeomorphism groups. Themain results are contained in the book " The structure of Classical diffeomorphisms" published by Kluwer Acad. Publishers in 1997. Current interst include Floer Homology and Gauge Theory.

Augustin Banyaga has published three books and 50 papers in Differential Topology and Geometry.
