Ray Layton, Ph.D.

Research Fellow for Environmental Safety, DuPont Pioneer

I have been interested in figuring out how things work since childhood, so it is no surprise I became a scientist. My background is in ecology, specifically looking at how ecological systems function and how they respond to different types of effects. Most of my early science work was with aquatic systems – small streams, rivers and ponds – looking at the effects of mining, agriculture, barge traffic, pesticides, etc.My interests have broadened over time, but the common theme has been risk assessment – always trying to understand (and reduce) the potential effects of various activities.

I have been at DuPont since 1989; for the first part of my career, I studied the potential environmental and human health risks of conventional chemical pesticides. Then in 2002, I moved to DuPont Pioneer where I founded and led the product safety group – a group of scientists dedicated to evaluating the environmental and human health and safety aspects of genetically modified crops.

I spend a lot of my personal time outdoors, cycling, hiking, running, paddling and working as a volunteer leader with the Boy Scouts. My goal is to use good science to leave this world, especially the outdoors that I love so much, a better place than how I found it.

A: Resistance can and has evolved to all forms of pest management, including chemical, biological, and cultural tools, and is not a unique concern for biotech-derived crops. When resistance does occur within insect populations, this is an economic issue for growers because they need to identify and use other types of insect pest control measures in order to continue producing their crop. However, the development of resistance in an insect or weed population has no direct effect on the...
