David Ensminger PhD student Email: dce133@psu.edu Office: 510 Mueller Laboratory Phone: 814.867.2252 Webpage: davidensminger.weebly.com Curriculum Vitae Education BSc 2012 University of California, Santa Cruz MSc 2014 Sonoma State University Research Interests My primary interests are in ecological physiology, specifically, how challenges in the environment can alter and change the traits, phenotypes, and behaviors of organisms. My background is with the HPA axis and some of its downstream hormonal and metabolic impacts in wild mammals, but I am currently also exploring how maternal stress can alter behavior, morphology, neurophysiology, and telomere length in wild lizards.
