David A. E. Bolton received his BSc in Human Kinetics (University of Guelph, Canada) and later obtained his Master’s degree in Exercise and Sports Sciences (University of Florida, USA) where he studied upper limb motor recovery in stroke patients. He then went on to complete his PhD degree in Neuroscience (University of Alberta, Canada) using both animal and human models to study balance regulation during walking. Following his PhD, he completed over three years of postdoctoral training at the University of Waterloo (Waterloo, Canada) where he helped develop a model to study cortical contributions to human balance. During this time, he also studied how the prefrontal cortex (an area critical for executive function) modifies sensory transmission according to task demands. Prior to starting his faculty position at Utah State University, he was a research fellow at Queens University Belfast (Belfast, United Kingdom) where he investigated neural adaptations that underlie motor learning, specifically addressing how these adaptations change with an aging nervous system.
Dr. Bolton’s current research focuses on the neural control of balance and the role of higher brain function in fall prevention, especially in older adults. He uses experimental tools to expose how the brain contributes to balance, which includes Electroencephalography (EEG) and Transcranial Magnetic Stimulation (TMS) that can directly measure what the brain is doing both before and after a fall. This extends upon traditional approaches where neural processes are inferred from external measures such as video motion capture, muscle responses and/or ground reaction forces. He also investigates cognitive processes such as Response Inhibition (i.e. the ability to suppress highly automatic, yet unwanted action) to understand how this ability relates to fall prevention. His long-term research goal is to provide a mechanistic understanding of what the brain does to help us avoid falls in the complex settings we face in daily life.

Mary A. Carskadon, PhD is an authority on adolescent sleep and circadian rhythms. Dr. Carskadon serves as director of the Chronobiology and Sleep Research Laboratory at Bradley Hospital and is a Professor of Psychiatry & Human Behavior at the Alpert Medical School. Carskadon’s early research with her graduate mentor, William C. Dement, culminated in the development and application of a standardized measure for daytime sleep tendency, the multiple sleep latency test. One focus of Dr. Carskadon’s scientific activities has been research examining interrelations between sleep regulatory systems (circadian timing system, sleep homeostat) and sleep/wake behavior of children, adolescents, and young adults. Her findings have raised public health issues regarding the consequences of insufficient sleep for adolescents as well as concerns about early starting times of schools. For example, adolescents’ circadian phase becomes later; their sleep “need” does not diminish; their sleep homeostatic system is modified in a way that alters sleep timing. Her work has affected education policy, prompting the AAP and others to promote later school timing for adolescents and many school districts to delay school start times.
Carskadon’s current research includes an evaluation of how sleep and circadian timing influence smell, taste, food choices, and food consumption in adolescents. This work has confirmed that obese early adolescents tend to eat a greater proportional of daily caloric intake at a later time of day and a later circadian phase than other adolescents. A new project examines sleep/health disparities in children with asthma. Proposed new research projects seek to (1) measure sleep and next-day cognitive effects of serial nights of alcohol use in adults (with Dr. McGeary); (2) evaluate the impact of chronic and acute caffeine ingestion on sleep bio-regulation in middle-school-aged children; (3) examine the role of sleep duration and regularity in epigenetic aging.
Dr. Carskadon is a distinguished alumna and honorary degree-holder of Gettysburg College and holds an earned doctorate in neuro- and bio-behavioral sciences from Stanford University, with a specialty in sleep research. Dr. Carskadon has received awards from several national organizations recognizing her scientific, educational, and public policy contributions. She is an elected Fellow of the Association for Psychological Science and of the American Association for the Advancement of Science.

Catherine Field is a CRC Tier I professor of Human Nutrition and Metabolism at the University of Alberta. Her research program centers on the effect of nutrition on the immune system. Current areas of research are: the role of polyunsaturated fats on the development of the infant’s immune system, the use of specific fatty acids in the prevention and treatment of breast cancer and identifying the association between nutritional status and maternal mental health and infant neuro-physical development.
She is a co-PI of a large maternal infant cohort, APrON (Alberta Pregnancy Outcomes and Nutrition). She has published more than 250 peer reviewed publications, been invited to speak more than 100 times nationally and internationally and has trained over a 100 students, from high school to post-doctoral levels, in research. Dr. Field received the McCalla and Killam Professorships from the University of Alberta, the Earl Willard McHenry Award for Leadership in Nutrition from the Canadian Nutrition Society and the Mary Mitchell Award for service to the Dietetic Profession in Alberta.
Dr. Field is currently the Past-President of, and only the second non-American, of the American Society for Nutrition, which is an academic society of researchers, educators and translators of nutrition with more than 7000 members globally. She current serves on the International Life Sciences Board of Trustees, is member of the CIHR Institute for Nutrition, Metabolism and Diabetes Advisory Board, and an Associate Editor for Advances in Nutrition. She was one of the co-founding Directors of the Cancer Research Institute of Northern Alberta in 2012 that brought together cancer researchers from 10 different Faculties at the University of Alberta.
