My interests are in agricultural biotechnology: transgenic product development; enabling technology development for agricultural biotechnology and strategy, planning and business development associated with the commercialization of transgenic and genomics technologies.
I currently work for Pioneer Hi-Bred (www.pioneer.com) as a Senior Research Director. Pioneer Hi-Bred International, Inc., a business unit of DuPont company, is the world's leading developer and supplier of advanced plant genetics to farmers worldwide. With headquarters in Des Moines, Iowa, Pioneer develops, produces and markets a full line of top-quality seeds and forage and grain additives and provides services to customers in nearly 70 countries. DuPont (www.dupont.com) is an integrated science company, delivering science-based solutions that make a difference in people's lives in food and nutrition, health care, apparel, home and construction, electronics and transportation.
Prior to joining Pioneer I work as Vice-President of Business Development & Operations for Verdia Inc. (www.verdiainc.com), a Silicon Valley agricultural biotechnology company, then a wholly owned subsidiary of Maxygen Inc (www.maxygen.com). Verdia’s directed molecular evolution technologies consisted of a toolbox of recombination and screening systems to optimize genes and proteins for use in transgenic agriculture.
Prior to joining Maxygen I worked with the biotechnology group at DEKALB Genetics Corporation, then the second largest corn seed company in the USA. At DEKALB I was responsible for transgenic corn product development participating in the development of insect and herbicide tolerant corn products.
I currently lecture course on transgenic product development in agriculture (PL BR 604) and the applications of molecular biology (BIO BM434).
