Introduction
R. Lee Penn is an American chemist and the Merck Professor of Chemistry at the University of Minnesota. Their research considers crystal growth, materials and environmental chemistry. Penn is a Fellow of the American Chemical Society. In 2020 Penn was awarded the University of Minnesota George W. Taylor Award for Distinguished Service.
Early life and education
Penn earned their undergraduate degree at Beloit College. They moved to the University of Wisconsin–Madison for their graduate studies, studying the growth and phase transformations of titanium dioxide. Penn moved to the Johns Hopkins University as a postdoctoral fellow.
Research and career
Penn started their independent career at the University of Minnesota in 2001. In 2008 they were awarded a McKnight Presidential Fellowship at the University of Minnesota. Penn studies the growth mechanisms of crystals and nanomaterials. Amongst such systems, Penn is interested in the self-assembly of metal oxide nanoparticles and their emergent phenomena. They are particularly interested in advanced imaging techniques, including scanning electron microscopy.
Academic service
Penn has been an active member of the American Chemical Society since 2011. They have served as chair of the American Chemical Society Division of Geochemistry. Penn is also committed to outreach, education and public engagement. They established a microscopy camp to introduce middle- and high school students in exploring microscopy and advanced materials characterisation techniques.

Personal life
Penn is non-binary and uses they/them pronouns. Penn also enjoys riding and racing bicycles, hauling all sorts of things by bicycle (including humans, furniture, and groceries), advocating for non-car based transportation, volunteering with Sisters Camelot to distribute food that would otherwise be discarded, advocating for folks who hold marginalized identities, working to remove barriers for folks who hold marginalized identities, parenting their fantastic teen (born in 2002), being a loving spouse, and 3D printing. Penn faced cancer treatment in 2011–2012.
