Link to CV


I grew up in the foothills of the Rocky Mountains in Loveland, Colorado, where I enjoyed cross country running, hiking, and camping. After living in a tent for a few months just outside of Rocky Mountain National Park at age 18, I attended Luther College in Decorah, Iowa, where I concentrated on chemistry and religious philosophy and ran varsity cross country and track. I participated in two National Science Foundation (NSF) Research Experience for Undergraduates (REU) programs involving organic synthesis one at Coe College in Cedar Rapids, Iowa under the supervision of Prof. Scott Stoudt, and one in Bangkok, Thailand under the supervision of Prof. Nopporn Thasana.

I joined the Stoddart and Stupp groups at Northwestern University as a joint student in 2008 and completed my PhD in organic chemistry in December 2013. The focus of my PhD research was on pi-conjugated organic molecules and materials for energy transduction. In the Stupp group I focused on small-molecule donors for organic photovoltaic devices, with an emphasis on comparing the behavior of families of synthetic homologues to uncover structure-property relationships. In the Stoddart group, I designed donor-acceptor oligorotaxanes and 'daisy chain' rotaxanes that can be efficiently prepared using click chemistry and actuated with thermal or electrochemical stimuli to express muscle-like mechanical motions. In addition, I have been blessed with several opportunities to carry out 10-week research stays abroad, once as a World Class University Visiting Student at the Korea Advanced Institute of Science and Technology in 2011, and twice in the group of Makoto Fujita at the University of Tokyo as a Global Center of Excellence Visiting Student in 2010 and then as a NSF East Asia and Pacific Summer Institutes (EAPSI) Fellow / JSPS Summer Program Fellow in 2013. I hope to lead an academic research group in the future.
