Aracely NewtonPost Doctoral Researcher
Ph.D., Stowers Institute. Kansas City MO, USAResearch Interests:
During her rebellious teenage years, spurred in part by the God-fearing Midwest climate, Aracely developed an interest in evolution, a process that is beautifully integrated with every aspect of biology. As an undergraduate, she began investigating one of evolutionary biology’s biggest conundrums – sexual reproduction – in the lab of Dr. Peter Baumann at the Stowers Institute for Medical Research in Kansas City, Missouri. She continued this research for her PhD dissertation at the University of Kansas Medical Center. By utilizing the unisexual Whiptail lizard (genus: Aspidoscelis), Aracely uncovered mechanisms that allow unisexual organisms to reproduce without sex.
Aracely’s postdoctoral research aims to understand the evolution of insulin signaling in Drosophila. She is supported by a Ruth L. Kirschstein National Research Service Award (NRSA) Fellowship.Selected Publications:
