He received his Ph.D. degree in Organic Chemistry at Purdue University in 1994, and started work as a hop chemist in 1993. Much of his earlier work involved developing new products and applications from hops for the brewing and non-brewing industries. He was also instrumental in developing HPLC calibration standards to accurately measuring various hop compounds in hop products and beer and is Secretary of the International Hop Standards Committee. Over the last few years his research has focused on dry hopping and its effects on bitterness, the IBU test, pH and beer foam as well as hazy IPA’s.
