My current work focuses on the coordination of endo- and exocytic vesicle transport at the plasma membrane in plant cells. I study how molecular transport machinery work together to support cell function, growth, and shape. I utilize genetic, molecular, and imaging tools to investigate the impact of disorganized or uncoupled vesicle transport machinery on plant cell function and physiology. I am also interested in endomembrane identity and how this affects vesicle transport and the localization/recycling of membrane proteins.

I like to think about and engage in science communication and education, particularly at the undergraduate level. I want to know more about how students learn to learn, and if the creative tools of experimental problem solving can contribute to student scholarship.
