Research Interests:
My principal area of interest is mammalian physiology and behavior, with a focus on the life history trade-offs associated with the timing of hormone secretion, reproductive effort, and aging. We perform integrative studies at the molecular, cellular, and organismal levels to elucidate the mechanisms that underlie reproductive aging. I pursue basic research that is integrative and comparative, while also being biomedically and ecologically relevant.
My lab generally follows Krogh’s Principle: “For a large number of problems, there will be some animal of choice, or a few such animals, in which it can most conveniently be studied.” (1929).

Prospective Students

Graduate and undergraduate students interested in comparative endocrinology and reproductive physiology and behavior are encouraged to apply. Our current model organisms are naked mole-rats and cheetahs – refer to research tab for details. However, students are encouraged to consider other systems that might better address their area(s) of interest. Trainees in my lab learn and use a variety of techniques to research questions at multiple levels of investigation (e.g. qRT-PCR, microarray, measures of immune function, immunohistochemistry, behavioral studies, mating tests).

Students interested in pursuing graduate work in my lab should contact me directly after they have read the statement of my current research interests and some of the papers that are listed on my publication page. If you decide our interests are well matched, please send a letter and c.v. via email (njp27@cornell.edu), and describe why you think my lab would be a good fit for you. I usually reply promptly, but send a follow-up email in a couple of weeks if you’ve not heard back from me.

I am a faculty member of four Graduate Fields, three of which are administratively housed in the College of Veterinary Medicine at Cornell University; the fourth is the Graduate Field of Neurobiology and Behavior (http://www.nbb.cornell.edu/gradstudiesoverview.shtml). Prospective students should apply to the Graduate Field that suits their interests best.

Zoology and Wildlife Conservation, Comparative Biomedical Sciences, and Molecular and Integrative Physiology are among several graduate fields that make up the Graduate Program in Biological and Biomedical Sciences at Cornell University. Prospective students for any of these fields apply to the in Biological and Biomedical Sciences program (/BBS/), and specify their field of choice. Details regarding the admissions and degree requirements for each field can be found at the associated links. As part of the Graduate Program in Biological and Biomedical Sciences, students in these fields are expected to complete three lab/research rotations during their first year of study. Based on that experience, students then inquire about joining the lab that suits them best.
