Collin Steen

I am an Assistant Professor of Chemistry at Lafayette College (starting Fall 2026), where I teach courses in general and physical chemistry and mentor undergraduate researchers in experimental physical chemistry and biophysics.

I completed my Ph.D. in physical chemistry at the University of California, Berkeley, working with Prof. Graham Fleming, where I used time-resolved laser spectroscopy to study photoprotection in intact algal cells, leaves, and plant thylakoid membranes. I then carried out postdoctoral research with Prof. Ke Xu at UC Berkeley, developing and applying single-molecule optical microscopies to probe lipid–lipid and lipid–protein interactions in supported and stacked lipid bilayers. As an undergraduate at Kalamazoo College (MI), I received an ACS-certified B.A. in chemistry alongside a minor in history and a concentration in biological physics. My senior thesis research was conducted at the University of Oregon, and focused on investigating the thermodynamics of polymer–surfactant systems at the air–water interface using laser spectroscopy.

I am deeply committed to mentoring undergraduate students and creating inclusive learning environments that foster curiosity, confidence, and scientific independence. I strive to make research a central part of undergraduate education and to support students as they explore scientific careers and graduate study.

I grew up in Elm Grove, Wisconsin. Outside the lab, I enjoy traveling, spending time in nature (especially near mountains and water), listening to Taylor Swift, and cheering on the Milwaukee Brewers.
