I am a toxicologist with a background in human health risk assessment. I earned my Ph.D. in toxicology from Texas A&M University and my B.S. in biology from the University of Missouri. Prior to joining Monsanto I was an Environmental Scientist with the California Environmental Protection Agency where I developed water quality standards. Subsequently, I worked for a private consulting firm conducting risk assessments. I started at Monsanto as a Biotechnology Regulatory Affairs manager responsible for obtaining global regulatory approvals for GMO crops. In 2014 I joined our Regulatory Policy and Scientific Affairs team.

Q: Are antibiotic resistance genes removed from GMOs? If so, how is this achieved? If not, are these marker genes tested for safety?

A: Antibiotic resistance genes are used in some GMOs to identify plants where the added DNA has been successfully incorporated. While this idea could understandably lead to questions -- Antibiotic resistance genes in my food? -- multiple safety reviews conducted by regulatory agencies around the world have confirmed that the presence of an antibiotic resistance gene does not pose any unique safety concerns.One of the first steps associated with GMO development is identifying the plants that...

A: As you and other farmers are well aware, weed control is one of the keys to good yields. GM crops that can tolerate glyphosate, the active ingredient in Roundup agricultural herbicides, provide a simplified approach to weed control and allow farmers to rely on an herbicide with a thoroughly documented record of safe use. Glyphosate is well known for its low toxicity to humans, farm animals and wildlife. From time to time, there are reports of glyphosate being detected in samples collected... Continue Reading
Q: How does Monsanto feel about GMOs affect on the natural order of the ecosystm. Have they considered it backfiring and Possibly causing a disaster? eg. The bees dying off. Although they may not be responsible for this. The consideration of altering...

A: This question touches on an important issue that is considered for all new GMO crop plants when they are reviewed by regulatory agencies in the United States and around the world. For plants modified to be protected against certain insect pests, assessments are conducted to determine whether nonpest species, such as bees and other beneficial organisms (earthworms, ladybugs, etc.), could suffer adverse effects. In the United States, data from these studies are submitted to EPA. In addition to... Continue Reading
Q: Are all the seeds you alter genetically patented by you and require man-made chemicals and licences to grow? If so, how sustainable is our future if a corporation OWNS the seeds of life inherited to us on this planet? If GMOs are natural then how is...

A: To answer the first part of the question, none of the seeds that is genetically altered “requires” a man-made chemical to grow—just soil, air and water. I’ll explain more at the bottom why that last part is important.A list of GMO crops currently approved or under consideration for cultivation in the United States is available from USDA’s website. On that site, you can see for yourself the data submitted for each GMO crop. One of the key studies GMO crop developers submit to USDA is a... Continue Reading
