From 1991 to 2007, Dr. Gauthier has been a research scientist at Environment Canada (EC) where he worked on the development of variational data assimilation, the 3D-Var, which was implemented in the operational suite in June 1997. He then supervised a team of research scientists, meteorologists, and computer scientists to work on a research and development program that resulted in the operational implementation of 4D-Var in March 2005. In 2003, Dr. Gauthier became head of the Data Assimilation and Satellite Meteorology Research section of Environment Canada. In November 2000, he became adjunct professor in the Department of Earth and Atmospheric Sciences at UQAM. In October 2007, he joined the department as associate professor.

His research interests are related to the methodology and applications of data assimilation and its relationship with atmospheric dynamics and predictability. More recently, he became interested in data assimilation with coupled atmospheric-chemistry models in the framework of a study funded by the European Space Agency. Assimilation with a coupled atmosphere-ocean model is also a new project that is carried out within the newly formed research network on Prediction and Predictability of the Global Atmosphere-Ocean System from Days to Decades funded by the Canadian foundation on Climate and Atmospheric Sciences (CFCAS).

Dr. Gauthier is involved in the THORPEX World Weather Research Programme, which is concerned with high impact weather forecasting over a period of 0 to 14 days. He is currently co-chairing the THORPEX working group on data assimilation and observing systems. He was one of the organizers of the First THORPEX International Science Symposium (Montréal, 2004).
