Research Interests

  • Physiological ecology of vertebrates
  • Conservation physiology
  • Morphological indicators of animal fitness
  • Migration biology of birds and insects
  • Improving methods of animal measurement

Research Projects

Multiple projects with various vertebrate and invertebrate organisms, including: investigating relationships between stress and white blood cells in vertebrates, effects of parasites (mostly blood parasites) on their hosts, elucidating the significance of intraspecific variation in color and morphology in organisms, studies of long-term trends in monarch butterfly populations in North America, and studying the nature of stopover ecology in migrating monarchs.
