PhD Student

After obtaining a bachelor's degree in Microbiology and a master's degree in Biomedical Genetics, I came to Iowa State University to do a PhD in the toxicology program. I joined Dr. Steven Bradbury's lab in January 2016. My research focuses on assessing risks of insecticides on monarch butterfly larvae. Milkweeds, the sole food source of monarch larvae, are being planted in midwestern states to help increase the butterfly population. Many milkweed habitats will be near corn and soybean fields where insecticides are often used for pest management. My research thus looks at the toxicity and exposure of these insecticides on monarch larvae. This will help inform options for milkweed placements (i.e., at what distances to plant milkweeds from agricultural fields) in states like Iowa.
