Biography

Birthplace:  Benin

Gangbo attended graduate school at Swiss Federale Institute of Technology where he earned his Ph.D. in 1992. From 1992 to 1993, Dr. Gangbo was a Postdoc Associate at Carnegie Mellon University. 1993--1995 he was located at the Mathematical Sciences Research Institute in Berkeley. Dr. Wifrid Gango joined the mathematics department of Georgia Tech as an Assistant Professor in 1995. In 1999 he was promoted to Associate professor. In 2001 he was promoted to Professor - from Ph.D. to Full Professor in nine years is very strong.

Professor Gango is Founder of "EcoAfrica," association of scientists involved in several projects in support of African countries. EcoAfrica was founded in 1990 in Switzerland and currently has six members. In the past years, EcoAfrica received funds mostly from Swiss institutions such as DDA, a Swiss Goverment Agency. Among other things, EcoAfrica has organized several workshops in Applied Mathematics in Senegal and intends to do the same in other countries in Africa.
