Research Interests:

  • Relationships between morphological, physiological, and behavioral specialization in arthropods, with a particular, but not exclusive, interest in solitary bees
  • Effects of polyols on insect survival and development
  • Effects of active learning on the development of process skills and retention of content in undergraduate students
