Hal Van Ryswyk

Hal Van Ryswyk is a Professor of Chemistry at Harvey Mudd College and the John Stauffer Professor of Chemistry. His research spans low-cost photovoltaics, quantum dot materials, and environmental chemistry, with a focus on community-based lead contamination studies and educational laboratory innovations.

• B.A., Carleton College
• Ph.D., University of Wisconsin-Madison

His work on thin-film solar cells and quantum dot inks aims to reduce solar energy costs through scalable manufacturing techniques. He has held leadership roles as Department Chair (1998-2008, 2018-2020) and served on the American Chemical Society's Petroleum Research Fund committee.

Awarded the John Stauffer Professorship, he emphasizes undergraduate research collaboration and has developed novel experiments for general chemistry, instrumental methods, and nanoscale materials laboratories. His service-learning initiatives engage local elementary schools in environmental science projects.
