Research Interests

  • I am a cell biologist who studies the proteins that allow mitochondria (the powerhouses of the cell!) to move around inside a cell. I am also intrigued by the intracellular protein signaling pathways involved in cell starvation and cell death, and my students and I use genetically engineered fluorescent proteins to observe these transformations firsthand. My research incorporates undergraduates, both inside and outside the classroom, and I challenge students to learn science by doing it. Together, we design and execute novel experiments to better understand how cells work using tissue culture cells, bacteria, yeast, or zebrafish embryos. In my free time during the summer, I serve as a venue technician at Fringe Festivals and review ‘science plays’ for their ability to accurately represent the scientific process.
