Association of Water Technologies. Robert J. Ferguson is the president of French Creek Software, Inc., a company he co-founded in 1989. His professional career includes positions with Nalco, Apollo, Mogul, Calgon, Chemlink, and Baker. Mr. Ferguson began modeling mineral scale formation and its control in 1974. Software he has developed is used for modeling cooling water, reverse osmosis, and oilfield chemistry. He is proud to be a Ray Baum Water Technologist of the Year honoree, the first AWT Innovation Award honoree, the first Process Cooling Innovation Award recipient, and a Ben Franklin Technology Center Innovation award winner. Mr. Ferguson was educated at the U.S. Naval Academy and the University of Minnesota and received a B.S. in biochemistry and microbiology.
