Biography

Guy Crosby developed an early fascination with chemistry in high school. With the help of his father he built a small laboratory in the basement of their home where he first experimented with the chemistry of food. Guy went on to obtain a B.S. degree in chemistry from the University of New Hampshire, and Ph. D. degree in organic chemistry from Brown University in 1969, where he studied the chemistry of cholesterol. Following graduate school he and his wife Christine moved to Palo Alto, California to spend two wonderful years as a postdoctoral research associate at Stanford University, where they met other organic chemists interested in food, wine, and cooking. Soon a position opened at a local Silicon Valley startup company developing new food ingredients where Guy was able to combine his expertise in organic chemistry with food science.

Ten years later he and his family moved to Princeton, New Jersey to work for FMC Corporation, initially in the Agricultural Products Division, and then as Director of R & D for the Food Ingredients Division, establishing a global network of laboratories in North America, Central America, Europe, and Asia. One more move brought them back home to Massachusetts in 1996 where Guy worked as Vice President of R & D for Opta Food Ingredients, Inc. until the end of 2001, culminating more than thirty years in food-related research and development.

Instead of retiring, Guy launched a new career in teaching. He started as a visiting lecturer teaching food science in the Department of Nutrition at the Harvard School of Public Health, and shortly thereafter with the Department of Chemistry and Food Science at Framingham State University, where he taught chemistry and food science as a full-time associate professor beginning in 2005. Guy Crosby - The Cooking Science GuyIn August of 2011 he retired from full-time teaching, but continues teaching as an adjunct associate professor at Harvard. In that time he has focused his research on the chemistry of food and taught food science to more than 350 students.

Looking for new avenues to combine science with his enthusiasm for cooking, Guy approached Cook’s Illustrated Magazine in 2004 to see if they needed help with food science. The magazine prides itself in taking a scientific approach to recipe development. In early 2005 he began working with the magazine as a consulting editor, and then as Science Editor a few years later. Six years ago Guy began recording a small number of science segments for the magazine’s PBS television show, America’s Test Kitchen. Since then he has recorded many television science segments with America’s Test Kitchen founder Christopher Kimball, and has recently worked with Chris to provide science commentary for ATK’s new radio program on National Public Radio.

Guy is a professional member of the American Chemical Society (44 years), Institute of Food Technologists, and American Society for Nutrition. He is also an external advisor for the first of its kind EcoGastronomy program at the University of New Hampshire. Guy has published 42 scientific papers, is the inventor on 17 U. S. patents, and co-author of a new book on The Science of Good Cooking, to be published in the fall of 2012 by America’s Test Kitchen.

On April 1, 2013 Guy was officially included in the first group of Certified Food Scientists (CFS) approved by the Institute of Food Technologists.
