Lab Affiliates
Pam Vanderzalm
Hometown: Rochester, NY
Education: Washington University in St. Louis B.S., University of California Berkeley, Ph.D., University of Chicago, Postdoc.
Project: I’m interested in growth control generally—how do tissues know when they’ve reached the “correct” size? Right now I’m interested in how connections between neurons and their targets reach the appropriate strength, and am studying how inhibition of BMP signaling during synapse development mediates this.
Hobbies: I am an official for US Figure Skating (Judge and Technical Controller) so you can often find me at rinks around the country if I’m not at work or with my family.
In another life, I would be a lawyer since I enjoy argument. At least my parents always told me I should become one!
