Research Interests:
I am interested in researching the sublethal effects of contaminants on fish reproduction. Specifically, my research will focus on the endocrine disrupting potential of contaminants using individual-level endpoints. My dissertation topic will establish and/or enhance hypothalamic-gonadal-pituitary axis computational models for a generic fish, bird, and mammal by incorporating neurotransmitters (gamma-aminobutyric acid, glutamate acetylcholine, dopamine), gonadotropin releasing hormone, follicle stimulating hormone and luteinizing hormone into each model. These models will predict cumulative vitellogenin and/or estradiol production which will then be used to estimate the amount of yolk for eggs or surviving oocytes and subsequently the total number of eggs produced. These fecundity estimates will then be incorporated into population models to infer population-level effects.
