Research Interests

My research focuses on characterizing the mechanisms that metabolically and developmentally integrate hosts and symbionts. Symbioses are mutually beneficial interactions between species. They are so beneficial that they are everywhere - in fact you comprise ten symbiotic bacterial cells for every human cell and those bacteria are important determinants of your phenotype, the ability of your body to heal wounds, and digest food. A compelling challenge in symbiosis research concerns identifying and characterizing the mechanisms of host/symbiont integration. I lead a research group that uses symbiotic partnerships involving one host interacting with one, or at most two, symbionts to identify fundamental design principles in the evolution of symbiosis.

Teaching Interests

My teaching focuses on developing research, writing, critical thinking and professional skills. I teach the Biology of Symbiosis to graduate students and upper level undergraduates. In this class we first gain an overview of the scope of symbiosis by reading and discussing Ed Yong’s book, “I contain multitudes: The microbes within us and a grander view of life”. In the remainder of the class we learn about symbiosis by engaging with the primary literature around biological concepts that include heritability, mutation, and genetic drift. At a graduate level, I also teach a Professional Skills class to first year graduate students.  This course covers everything from learning to read and present science to learning about writing emails and memos, career planning, goal setting and developing productive mentor/mentee relationships. At an undergraduate level, I teach two sections of the Introductory Biology HHMI CHEM/BIO inquiry-based laboratories to UM freshman. My primary goal as a teacher is to engage my students to think actively and critically in class about the material being presented so as to push at the boundaries of their understanding and world-view.
