Timothy Dennehy joined Monsanto Global Scientific Affairs in 2008, ending 25 years as an academic. He has B.S. and Ph.D. degrees in Entomology from the University of California, Davis. He was on the faculty of Cornell University for a decade, and then moved to the University of Arizona. There he was a member of a research and extension team recognized internationally for bringing conventional pesticide use in Arizona cotton to historic low levels. In 2006 he was recognized with the title University Distinguished Professor, the highest honor awarded at the University of Arizona for faculty outreach. Tim has authored over 200 publications. With some apprehension, he has agreed to share with us perspectives on the often-misunderstood and evocative issues surrounding biotechnology. What do we know about the safety of bioengineered foods and what are the alternatives? Can we feed the world with organic agriculture? Is sustainable agriculture a scientifically-sound middle ground?
