Stephanie Homan

I knew right away I wanted to be a chemistry major as an undergraduate at Berry College, a small liberal arts college in the mountains of north Georgia. It wasn’t until my junior year I realized I wanted to teach chemistry at a liberal arts school, where I could build lasting relationships with my students in the classroom, the research laboratory, and the greater college community. My experiences in graduate school at the University of North Carolina at Chapel Hill and as a postdoctoral research assistant at Northwestern University shaped me into the scientist I am now, and it is great to be back at a small liberal arts college.

My research interests lie at the interface of physical, inorganic, and materials chemistry. Students in my research group make semiconductor nanocrystalline quantum dots and study their unique optical properties using instruments made in the group. The quantum dot systems will be used as florescent tags in biological imaging and photovoltaic devices. I arrived at McDaniel College in 2018, and have taught Foundations of Physical Chemistry, General Chemistry, Materials Mimicking Nature First Year Seminar, and Senior Capstone courses.
