Mallory Marshall joined the Samford faculty in 2014 after completing a PhD in Exercise Physiology at Michigan State University. She studies the physical activity behaviors of pregnant and postpartum women using various physical activity monitors, and is particularly interested in walking behavior and how daily steps and stepping rates change as pregnancy progresses. She is also interested in the role of physical activity during pregnancy on offspring growth and health, as well as social support related to physical activity during pregnancy. She spends much of her time teaching and mentoring undergraduate students through the research process as they take a required series of courses designed to facilitate completion of an IRB-approved research project from design to analysis to formal presentation. She believes that the research process is a valuable tool to teach students to defend their decisions with data and research, and loves to help students see the parallels between research and the Christian life, where believers make decisions based upon the truths found in Scripture.
