The 2014-2015 Harry C. Yeatman Award in Biology was awarded to Biology major Angelica De Freitas and Ecology & Biodiversity major Callie Oldfield at the annual Biology Department Junior-Senior Event in Harris Commons of Spencer Hall.    Students who receive the Yeatman Award are Senior Biology or Ecology & Biodiversity Majors chosen for their scholastic achievement, leadership qualities and an appreciation for biology as a discipline which are characteristics exemplary of Dr. Yeatman’s life and career.

Angelica De Freitas, Research Supervisor: Dr. Alyssa Summers
Angelica currently works in Summers Lab where she studies the role of histone deactylase 3 in tumorigenesis.  She along with two other students presented research in the 2014 Scholarship Sewanee Poster Session titled "The Role of HDAC in Tumorigenesis" The poster won second place in the Biological Sciences category for the McCrady Prize in Best Poster.  Angelica's research beyond Sewanee has included investigating the link in perception deficits in children with autism spectrum disorder and speech and sound disorders at Yale University Child Study Center in New Haven, CT.  She also participated in the Vanderbilt Summer Science Academy Undergraduate Research Program in where she investigated the role of cytokine interleukin-4 induced glycolyisis in proliferation and colonization ability of mammary cancer cells in metabolically hostile environments.

Callie Oldfield, Research Supervisor: Dr. Jonathan Evans
Callie has worked on several research projects with Dr. Jonathan Evans.  One such project has yielded a publication from research conducted in Dr. Evans’ Field Studies in Belize course titled “Coral preference of the polychaete,Spirobranchus giganteus, in the Belizean Barrier Reef”  in Papers and Publications: Interdisciplinary Journal of Undergraduate Research.   Callie's presentation of this research won first prize in zoology at the 2014 TN Academy of Sciences Collegiate Competition.   She also presented this research at Scholarship Sewanee 2014.  Additionally, Callie is first author on a manuscript to be submitted to Oecologia titled    ‘Invasive species perpetuation resulting from a “farming” mutualism within a barrier island ecosystem.’  She has conducted independent research with Professor Evans over the last two years working on the dynamics of chestnut oak populations.  Callie has also received Yeatman funding and Herbarium funding as a summer intern in 2013 and 2014.  As a leader, Callie designed and led all-day SEI module for high school students on her chestnut oak research in the summer of 2014.  She also created the iNaturalist site for Evans’ Belize Program where she entered information and photos of more than 400 species.
