Zach VanOrman
Assistant Professor of Chemistry
Dr. Zach VanOrman began working at Hope College as an assistant professor of chemistry in 2025. He will be teaching General Chemistry I and II lecture and lab sections. His research mainly involves the synthesis and engineering of semiconductor nanocrystals, which is 1–10 nm in size, roughly 100,000 times smaller than the diameter of a human hair. His research is for applications in quantum information and clean energy generation.
Before his time at Hope, he was a postdoctoral researcher at Harvard (Rowland Institute) from 2022–2024 and then a research scientist at The École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland.

Outside Hope
Zach is an avid sports fan (Green Bay Packers and Detroit Tigers), and has played sports his entire life, including football all throughout college at Hillsdale College. Currently, he loves playing pickup basketball and running, even completing two marathons. He lives in Holland with his wife and their dog, Cooper, where they all like going on long walks and enjoying the water. They also love traveling (hence the European postdoc), mostly to try new delicious food!
