Bio

Sara grew up in Michigan, spending her summers on the waters of northern Lake Huron. There, she nurtured her passion for animals, nature, and conservation from an early age. She pursued her B.Sc. in zoology at Duke University. Following a post-graduate research fellowship at the Max Planck Institute for Behavioral Physiology, she began her long association with the department of zoological research at the Smithsonian Institution’s National Zoo, first as a PhD student (jointly with the University of Maryland) working on the physiological ecology of sea lions in the outer California Channel Islands and subsequently as a long-term Smithsonian research associate.

After receiving her PhD, she held a postdoctoral fellowship at Georgetown University and then a Natural Sciences and Engineering Research Council of Canada (NSERC) international postdoctoral fellowship at the Canadian Institute of Fisheries Technology to work primarily on developing methods for elucidating marine mammal diets and aquatic food webs.

In 1994, Sara became a professor in the biology department at Dalhousie University, establishing a long-term research program on physiological ecology and fat metabolism in marine mammals, seabirds and Holarctic bears. Sara is a former NSERC EWR Steacie Fellow, Killam Prize Awardee, University Research Fellow, and is a Fellow of the Royal Society of Canada, Academy of Science.

Sara became the scientific director of OTN as it was being launched in 2008 and has co-led and directed OTN with executive director, Fred Whoriskey, ever since. Together, they have overseen the growth of OTN from its launch as a seven-year International Joint Venture Project into a preeminent Canada Foundation for Innovation national research facility (Major Sciences Initiative). Although continuing to run her lab, research program, and oversee OTN, Sara still returns every summer to Michigan’s northern Lake Huron to sail, swim and spend time with childhood friends and family.
