Josiane L. Broussard, Ph.D., Laboratory Director

Josie is an Assistant Professor at Colorado State University in the Department of Health and Exercise Science. Before CSU she was a mentored junior faculty member at the University of Colorado Boulder where she trained in circadian biology with Professor Kenneth P. Wright, Jr. Prior to Colorado, Josie completed her postdoctoral work with Dr. Richard Bergman in Los Angeles, focused on obesity and insulin resistance in an animal model. For her graduate work, Josie studied sleep and metabolism with Dr. Eve Van Cauter at the University of Chicago. Before that, she majored in neuroscience at Brandeis University in Waltham, MA and before THAT she grew up on the coast of Maine. 

Ellen Lyon, M.S., Laboratory Manager

Ellen is a Research Associate managing the SAM Lab at CSU. She has a background in clinical exercise physiology and previously worked in diabetes and vascular research at the University of Colorado Anschutz Medical Campus. She keeps all of us organized and the lab running by overseeing every aspect of our research (as Josie would say--she is the "real" boss). She takes care of IRB regulatory and compliance work, data collection and organization, participant recruitment and communication, student and staff training, scheduling, conducting study visits...and whatever else needs to be done!

Sarah J. Morton, M.S., PhD Student

Sarah graduated with her Master's degree in Integrative Physiology from the University of Colorado Boulder and has been involved in sleep research since her undergraduate days. As our most senior student, Sarah is responsible for general study organization, assays, student training and tissue processing. Sarah is a certified EMT so also takes care of the IVs in all of our studies. When she's not in the lab, you will find her playing on soccer teams all over the city and rock climbing.


Sophie Seward, M.S., PhD Student

Sophie graduated with her Master's degree in Exercise & Sport Science from Western Colorado University and is now pursuing her PhD in Human Bioenergetics. As a SAMmie she will investigate countermeasures to circadian misalignment. In Spring 2018 and 2019, Sophie qualified for and ran in the USA Olympic Trials for the marathon!
