After the two-year fellowship, Gaucher served as President of the Foundation for Applied Molecular Evolution.

Gaucher was hired as an Associate Professor by the Georgia Institute of Technology in 2008 [1][3][4] The Gaucher group conducts basic and applied research at the interface of molecular evolution and synthetic biology. As of February 2016, his h-index, as calculated by Google Scholar, is 25.[5]

Gaucher is also the founder and president of the early-stage biotechnology company General Genomics. His company exploits novel platforms to engineer proteins for the biomedical and industrial sectors.
