About Us


Dennis Seisun has worked in England, France, Belgium, and since 1980, has been based in San Diego, California. He graduated from Bath University in England with a bachelor of science degree in engineering and a master of science degree in industrial marketing. He worked as an engineer for Foster Wheeler, as a consultant for C.H. Kline S.A. in Brussels, and for Kelco (then a division of Merck) as commercial development product manager. In 1985, Dennis founded IMR International and has since focused his attentions on the food hydrocolloid markets of the U.S., E.U., China, India, and many other parts of the world. The Quarterly Review of Food Hydrocolloids was launched in 1991. It has since, become established as a comprehensive and independent source of information on the food hydrocolloid market. In addition IMR has chaired the International Conference on Food Hydrocolloids since 1995 alternating between the USA and Europe.
