Research statement

I am passionate about both biology and biology-education research. My research interests have been, and continue to be, broad in scope and mission. I’ve published papers on teaching with technology, barriers to teaching and learning evolution, and gender disparities in the sciences. I have also published articles on strategies for engaging students in large lectures, including work with the Active Learning Classrooms project at the University of Minnesota. Current work involves identifying which elements of course-based research experiences (CUREs) are key to promoting scientific literacy; identifying and countering barriers to learning science; evolution education in Galápagos; and facilitating meaningful group interactions in the large-lecture setting.

Teaching statement

Teaching biology should be easy. We are all born scientists. We emerge with limitless curiosity and an insatiable demand to know “what” and “why.” But the students I encounter have experienced a lot since they were infants, and some of their experiences have made them cynical, less inquisitive, and afraid of ambiguity. My challenge, and therefore my philosophy of teaching, is to re-instill love of the unknown, promote confidence in addressing ambiguity, and foster delight in discovery. At the same time, I need to help students understand the personal relevance of natural science, and learn some fundamentals of modern biology. I also want them to realize that science is a social endeavor, directed by the questions we ask and guided by contemporary culture.

Favorite teaching innovation or approach

My philosophy of teaching is exemplified by the development and delivery of the introductory biology course, “Evolution and Biology of Sex.” Essentially, I am exploiting what may be the topic of greatest universal interest — sex — to teach about evolution, the process of science, and the personal dimension of scientific research. My job is easier because students come to the class with many questions, and when it comes to the evolution of human mating and reproductive biology, there are many unknowns. Each class period is structured around a hook (“what the heck is going on?”) to engage the students, a mini-lecture or two (for content delivery), small-group activities and discussion (to reinforce content), and whole-group synthesis (for a “big picture” view of the topic).

Sadie Hebert (HHMI post-doctoral fellow) and I have developed a multi-week laboratory exercise that engages the sex students in meaningful research that is sexy and authentic, while being inexpensive and logistically manageable. Specifically, students discuss contemporary research on sex in the bean beetle, Callosobruchus maculatus, and then develop and test hypotheses related to bean-beetle sex.
