Research Interests

Molecular Mechanisms

My research interests include understanding the molecular mechanisms underlying how cells control their entry and progression through the cell cycle. In particular, I am interested in determining how cells decide whether or not to replicate their DNA and the control mechanisms that underlie that decision.

Teaching Statement

As an instructor, I am interested in creating an interactive learning experience in the large lecture courses that I teach. Integrating new technologies such as the i>clicker audience response system is an important part of this endeavor, as well as providing students with opportunities to consult with each other before answering clicker or other in-class questions. I often use a problem-based approach to discuss different aspects of cellular and molecular biology and enjoy using “real-world” examples to make the subject material seem more relevant. Beyond conceptual understanding of the material, I also emphasize development of problem-solving and critical-thinking skills, as these are skills that will be useful in many aspects of the personal and academic life of the student.
