I am a Professor in the Department of Biology at St Catherine University, currently serving a 3-year term as Co-Chair of the department. I am also a Carondelet Scholar and Research Director of the Women's Health Integrative Research (WHIR) Center. I work in the areas of physiology and physical anthropology (PhD from UW-Madison), with a particular focus on the locomotor physiology and biomechanics of humans in contemporary as well as early human populations. I teach Comparative Physiology, Biology of Women, and courses in the new introductory biology sequence. I am active in a number of departmental, University, and professional service opportunities that fit my skills and interests.

My research is done collaboratively with undergraduate students and immerses them in all aspects of the experimental process: protocol design, data collection, analysis, and publishing and presenting results. My research looks at factors influencing the metabolic cost of walking and running in humans, particularly while carrying “loads” (children, belly fat, backpacks, or during pregnancy). Recently, my collaborators and I have focused on the energy flux in females and their offspring, including thermoregulation in mothers and their infants and the costs of carrying infants and toddlers. Currently, my research team is engaged in a three-year $55,000 study – KidCarry: Where to Carry Kids? A Comparison of Women And Men During Walking.

My research centers on the energetic costs involved in human movement and the factors that interact in determining this important part of our energy budgets. In what ways are humans physiologically and anatomically “designed” for efficient locomotion? What physiological, morphological, behavioral, and environmental factors determine the energetic cost of locomotion? How are the various systems involved in locomotion integrated to produce the optimally tuned movements that we observe? Pursuing these questions takes me across the boundaries of a number of disciplines: exercise physiology, physical anthropology, neurophysiology, functional morphology, biomechanics, nonlinear dynamics, and statistics. I have applied my findings to understanding energy balance in modern humans as well as in early human populations (early Homo sapiens and potential ancestors). My research looks at factors influencing the metabolic cost of walking and running in humans, particularly while carrying “loads” (children, belly fat, backpacks, or during pregnancy). The majority of my research is done collaboratively with undergraduate students and immerses them in all aspects of the experimental process: protocol design, data collection, analysis, and publishing and presenting results.

As Research Director of the WHIR Center, I am also working with an interprofessional clinical team to develop a research agenda around falls prevention in community dwelling elders.
