Overvoorde is a plant molecular biologist. His research focuses on increasing our
understanding of how the plant hormone, auxin, is recognized by plant cells and how the
process affects plant growth and development. He teaches courses in cell biology, plant
biology and physiology as well as genetics. 

EDUCATION: B.S., Calvin College Ph.D., Washington State University 

Overvoorde has been teaching at Macalester since 2001.
