Molly Dieterich Mabin

During my undergraduate studies I developed a strong interest in ecology and the interactions between plants and animals. At OSU my thesis research focused on biological control of cucumber beetles within cucurbit crops. I examined how different farm and field management techniques affect the community of predatory arthropods within those crops, and if differences within that community affects predation on cucumber beetles. Currently, I am helping with a variety of projects in the lab that focus on how pollinator behavior affects gene flow between genetically engineered and conventional alfalfa. When not at work, I like to go hiking and camping with my family!

As an undergraduate, I developed a love of invertebrate research working with land snails and benthic invertebrates. During my time at USD, I worked primarily with the Hine's emerald dragonfly, a federally listed endangered species, and the Captive Breeding Program. My thesis focused on the relationship and behavioral interactions between dragonfly larvae and devil crayfish, their temperamental roommates. Currently, I am helping on various projects in the lab that focus on pollinator behavior affecting gene flow and different management techniques for alfalfa production. Outside of the workplace, I am often found exploring with my family and the greatest dog, Hiro.

I discovered my love for behavioral ecology and entomology while an undergraduate student at Elon University. My research focused on the multimodal communication behavior in a group of neotropical katydids; I explored the functions of acoustic and vibrational signals in the blue-headed katydid (Docidocercus gigliotosi). I am currently working on projects examining how the pollination behavior of different bee species affects gene flow between alfalfa plants as well as a project investigating scent as a nest attractant. While I'm not working I like to explore Wisconsin and go hiking. 

Postdoctoral Trainees

Fabiana Palmieri Fragoso - July 2017 - Present

I have a B.S. and teaching degree in Biological Sciences from the University of Sao Paulo, Brazil. As an undergraduate, I investigated the reinstatement of litter decomposition in areas of Atlantic Forest undergoing restoration. Subsequently, I earned a M.S. and Ph.D. in Entomology studying how pollinator communities, mainly bees, respond to forest restoration. Currently, I am assessing how how pollinator behavior affects gene flow of genetically engineered crops at the landscape level. Using alfalfa and bumblebees as the study system, I am analyzing the decision making process used to move between patches in various landscapes. I am also obtaining empirical evidence of gene flow from genetically engineered to conventional patches of alfalfa. These results will contribute to improved management strategies and enhanced coexistence among genetically engineered, organic, and export crop markets.

I am trained as a disease ecologist and am interested in tri-trophic interactions. During my PhD (Elderd Lab) I studied the interactions between a predator and a pathogen that attacked the same prey/host. Now, I study gene flow from crops to roadside alfalfa populations. I am particularly interested in the biology (plant size, number of flowers, etc) and ecology (pollinator species, diseases, etc) of roadside alfalfa and how they differ between glyphosate resistant and conventional plants. On the side I enjoy playing soccer and taking road trips. Check out my site here:
