Research Interests

  • My research focuses on investigating the mechanisms responsible for sarcopenia (the age-related loss of skeletal muscle mass and strength) and developing exercise interventions for the treatment/prevention of sarcopenia.  Additionally, we are interested in mechanisms responsible for skeletal muscle recovery and regeneration after injury. More specifically, my laboratory investigates the role inflammation plays in muscle atrophy, as well as during recovery and regeneration after injury.

Current research projects include:

  • Skeletal muscle repair after injury using a downhill running model in mice
  • Natural plant steroid (phytoecdysteroids) supplementation during skeletal muscle repair from injury in mice - Collaboration with Dr. Andy Shanely
  • Determination of exercise-induced skeletal muscle inflammation in young and old individuals using microdialysis - Collaboration with Dr. Ed Merritt
  • Effect of Cycling on Mechanical Efficiency and Running Economy in Triathletes -Collaboration w/ Dr. McBride

Future projects:

  • Determining whether exercise training improves oxidative function in skeletal muscle tissue in a pig model of heart failure with preserved ejection fraction (HFpEF) -Collaboration with Dr. Craig Emter (University of Missouri)
  • Effect of Conjugated Linoleic Acid Supplementation on Muscle Mass and Strength in Elderly Men and Women – Collaboration with Dr. David Nieman (ASU-HumanPerformance Lab at the North Carolina Research Campus in Kannapolis, NC)
