Teaching Interests

My primary goal in teaching has always been to challenge students to think independently. In both classroom and graduate teaching I have stressed the principle that current scientific explanations are really working hypotheses, and as far as possible I have tried to point out the limitations of these hypotheses and where alternative explanations may also be appropriate.
