I am a comparative physiologist with primary interests in respiratory, cardiovascular and exercise physiology in ectothermic vertebrates. Recent projects include regulation of lymphatics and baroreflexes in anuran amphibians, and meta-analyses of maximal O2 and CO2 flux rates in vertebrates. 

Education

  • M.S. 1985. Portland State University (Biology)
  • B.S. 1980. Lewis and Clark College (Biology)
