Daniela Drummond-Barbosa

Daniela Drummond-Barbosa is a Brazilian-American geneticist who is a professor of genetics at the University of Wisconsin–Madison. These contributions have broader implications detailing diet and temperature's impacts on fertility.

Early life and education Drummond-Barbosa was born in Los Angeles, California, and grew up in Belo Horizonte in Brazil. She earned her undergraduate degree in biochemistry and immunology at the Federal University of Minas Gerais in 1991. She moved to New Haven, Connecticut, for her graduate studies at Yale University. Drummond-Barbosa pursued further education where she worked with Daniel DiMaio for her P.h.D. research. Her doctoral research focused on the interactions between platelet-derived growth factor receptors and the bovine papillomavirus E5 protein. There, she continued her research considering adult stem cells' ability to sense and respond to external and systemic environments such as manipulated diets, temperature, and other stressors. She has focused on the ovarian stem cells of Drosophila and how they respond to diet, concentrating specifically on hormones, insulin and adipose tissue.

Implications Drummond-Barbosa's research introduces a novel study surrounding the control and maintenance of germline stem cells in Drosophila, allowing for broader impacts such as infertility, obesity, and climate change to be understood. 2006 Vanderbilt University Chancellor's Award for Research 2017 Johns Hopkins University Shikani/El Hibri Prize for Discovery & Innovation
