I taught at Midland University from 2003-2007. I have been teaching at Bryan College of Health Sciences since 2006. I am also an adjunct faculty member at Doane University.
My research background focuses on the study of birds. Ecophysiology of birds, (1987-1990), behavioral genetics of birds (1991-1996). I currently work on the effects of endocrine disruptors on avian vocalization.
