In this episode, I chat with Dr Kathleen Reinhardt regarding her research into primates and how their sleep has evolved with their environment.  Dr Reinhardt grew up in New York, completing a Bachelor of Arts in Anthropology at Stony Brook University before moving to the United Kingdom for further study.  She completed a Master of Science in Primate Conservation and a PhD in Anthropology and Geography at Oxford Brookes University in Oxford before moving to Canada.  Dr Reinhardt is currently based at the University of Calgary where she is a Postdoctoral Fellow in Transdisciplinary Research with the Faculty of Arts.  Kathleen is also an accomplished scientific illustrator and wildlife artist.                                          In this episode, Kathleen and I discuss:  A new term for me, Torpor, and its meaning.  Torpor and primates, with a focus on strepsirrhines.  Another new term, cathermal.  The similarities between primate and human sleep behaviour.  The impact of humans on primate habitat and behaviours.  The impact of light on animals and humans.  Random thoughts and good wildlife documentaries.  Kathleen’s wildlife artwork.  Dreams in different environments.  The ups and downs of research.    Website: https://www.kathleenreinhardt.com/  Email: kathleen.reinhardt@ucalgary.ca  Instagram: https://www.instagram.com/theart_ofscience/
