She earned her master’s of science in Kinesiology from the University of Massachusetts Amherst (UMass), where her research focused on human-animal interaction influences on physical activity. Sara explored the role of dog ownership and dog walking in enhancing physical activity levels and improving mental health among older adults. During her time at UMass, Sara served as a Teaching Assistant for various courses, including Introduction to Kinesiology, Human Performance, and Nutrition. She is currently a Research Assistant for the Time to Move Randomized Crossover Trial. Sara enjoys exploring new recipes in the kitchen and finds peace in outdoor swimming.
Mikayla Greene
Mikayla Greene earned her undergraduate degree in Exercise and Sport Science at the University of Georgia, where she discovered her passion for using exercise to support individuals during important life stages. This led her to pursue avenues focused on the intersection of exercise and women’s health, particularly maternal health, and maternal mental health. Mikayla is pursuing her master’s degree in Exercise Physiology under Dr. Lyndsey Hornbuckle-Lampkin in the Department of Kinesiology, Recreation, and Sport Studies at the University of Tennessee, Knoxville. She is a Research Assistant for the Time to Move Randomized Crossover Trial. Mikayla enjoys volunteering in community spaces, staying active through exercise, and spending quality time with her two dogs.
