About

Scientist and educator by day, musician by night, and citizen of the cosmos always. Josh recently completed his PhD from the Department of Integrative Biology at UW-Madison and is a former Marie Christine Kohler Interdisciplinary Fellow @WID. When not in the classroom or lab, he’s likely to be found performing as a percussionist in a handful of world music groups in town, or listening to podcasts on artificial intelligence, free will, complexity science, or something of the like.

Education

  • B.A., Zoology, Miami University
  • B.A., Psychology, minor in Neuroscience, Miami University
  • Ph.D., Zoology, University of Wisconsin–Madison  

Research Description

Research over the last several decades indicates that species exhibiting “genetic” monogamy are exceedingly rare in nature, despite numerous examples of “socially” monogamous animals. Unlike most rodents, the California mouse is strictly monogamous in the wild, making it an excellent model to study mechanisms of mammalian mate fidelity. Josh's PhD research examined how hormones and the social environment interact to produce adaptive behavior in this species, including pair bond regulation and mate fidelity, with a special focus on ultrasonic communication. Given the widespread use of rodents in both basic and clinical research, measures incorporating ultrasonic vocalizations are becoming increasingly common for a variety of uses. One such use is to assess functional communication deficits in rodent models of communicative disorders. Josh’s secondary research focus sought to understand the neuropathology of Parkinson’s disease as it relates to speech deficits in an effort to devise effective new treatments. Projects involve assessment of vocal signal abnormalities in a PINK1 gene knock-out rat model of Parkinson’s disease and assessment of possible communicative impacts manifest from these vocal deficits via ultrasonic playback. In addition to basic biology, Josh's research interests include the positive impacts of active learning in undergraduate science education.
