Lisa Shammas. Lisa is a Biology major from Troy, Michigan. She was awarded a travel grant from the Endocrine Society to present her cancer research at the society’s 95th Annual Meeting and Expo in San Francisco last summer.
Alexandra Zetye. Alexandra is from Rochester Hills, Michigan and is majoring in Engineering Biology, Mathematics, Piano Performance, and French. She is a coauthor on a paper describing a mathematical model of Chagas disease.
Current undergraduates interested in applying for the award next year should see the OU-Goldwater website. The application webpage won't be available for the 2015 competition until later this fall, but expect an application procedure and timeline very similar to that used in 2014.
This work presents a new mathematical model for the domestic transmission of Chagas disease, a parasitic disease affecting humans and other mammals throughout Central and South America. The model takes into account congenital transmission in both humans and domestic mammals as well as oral transmission in domestic mammals. The model has time-dependent coefficients to account for seasonality and consists of four nonlinear differential equations, one of which has a delay, for the populations of vectors, infected vectors, infected humans, and infected mammals in the domestic setting. Computer simulations show that congenital transmission has a modest effect on infection while oral transmission in domestic mammals substantially contributes to the spread of the disease. In particular, oral transmission provides an alternative to vector biting as an infection route for the domestic mammals, who are key to the infection cycle. This may lead to high infection rates in domestic mammals even when the vectors have a low preference for biting them, and ultimately results in high infection levels in humans.
The Goldwater website lists Zetye's career goals as a "Dual M.D./Ph.D in Bioengineering. Conduct research in medical nanotechnology and teach at the university level."
OU undergraduate Alexandra Zetye received an honorable mention from the Barry M. Goldwater Scholarship Program in 2014
