The areas of biology in which I am best qualified and enjoy teaching most include Ecology (general, biophysical, behavioral, physiological, population, evolutionary, and others), Environmental Physiology, Evolution, and Vertebrate Biology. I am convinced that all of these areas of biology can be taught most effectively when course material draws from the pertinent expertise of other academic disciplines. Furthermore, I believe that the important complementarities of theoretical, experimental, and descriptive approaches to biological sciences should be illustrated at every level. I tend to subordinate memorizing facts to cultivating abilities for creative synthesis of knowledge and ideas.
