Jeffrey Dumont

Senior Data Scientist

Jeffrey Dumont is an expert modeler, researcher, and data scientist. He manages the technical and analytical aspects of complex modeling and survey projects for both public and private sector clients in the United States and abroad. Since joining RSG in 2006, he has played a significant role in survey sample design, development of efficient experimental designs, and advanced statistical analysis of survey data for hundreds of projects. Jeff’s primary interests are in bringing advanced methods to solve real-world problems. Currently, he is exploring how to fuse secondary data with survey data to improve demand forecasts.

Jeff enjoys fly-fishing in Vermont’s rivers and streams and volunteering as a judge in the Vermont State Math and Science Fair. He lives in White River Junction, Vermont with his wife and two daughters.
