Dr. Day joined the Physical Therapy department as an Assistant Professor in Fall 2008. She received her B.S. in Exercise Science at the Southern Connecticut State University where she also began a career in research, completing and defending an undergraduate research thesis. After spending a year as a research technician at Yale University, Dr. Day moved to Boulder, Colorado to pursue her graduate studies. She received her M.S. in Kinesiology and Applied Physiology at CU-Boulder, then completed her dissertation studies on the effects of sex hormone suppression on resting metabolic rate and sympathetic nervous system activity at the University of Colorado Health Sciences Center in Denver. After successful defense of her dissertation studies, Dr. Day spent a year at CU-Denver as a postdoctoral fellow in the Division of Geriatric Medicine, continuing to study the association between estrogens and exercise with bone density and weight management in both pre- and post-menopausal women.

Dr. Day moved back to the New England area in 2005 and spent 2 years working at the United States Army Research Institute of Environmental Medicine in Natick, Massachusetts, designing research projects to address the metabolic and weight-management challenges faced by female & male soldiers. During this time Dr. Day discovered a passion for teaching while spending evenings as an adjunct professor at local community colleges. She spent one year as an assistant professor in the Department of Exercise and Sport Performance at the University of New England in Biddeford, Maine before accepting her current position here at UMass-Lowell.

Dr. Day has presented her research nationally and internationally and continues to bring awareness to sex differences in exercise and health issues through media interviews (she has recently been quoted on MSNBC). In addition to her teaching and research interests, Dr. Day is a certified yoga instructor and would eventually like to incorporate yoga into her scientific studies.
