Research/teaching interests

Research:

  • Human cardiovascular regulation
  • Neural and non-neural control of blood pressure
  • Differences in cardiovascular regulation due to gender and aging

Teaching:

  • Exercise physiology
  • Functional anatomy and kinesiology

Academic highlights  

  • Postdoctoral: University of Texas Southwestern Medical Center, 2009-2011
  • PhD: Pennsylvania State University, 2009
  • BS: University of Puget Sound, 2002

My laboratory is interested in examining the role of neural and non-neural control of blood pressure in humans.  We are particularly interested in the differences in blood pressure regulation between women and men, as well as the changes that occur due to aging and alterations in sex hormone exposure.
