  • Portrait of Bryan

    Bryan Holmes | STEM Education Specialist

    Bryan holds a B.S. in Secondary Education and a master’s degree from the Harvard Graduate School of Education, where his primary interest was the relationship between formal and informal education. He spent a summer working and studying informal education at the National Air and Space Museum. Prior to joining CuriOdyssey in late 2010, Bryan taught high school physics and chemistry in rural Maine, his home state, and spent his summers plastering in a fresco shop. His interests sprawl across disciplines, but include classical history, physics, carpentry, and anything anyone will teach him. In his spare time, Bryan enjoys cooking, hiking, and seeking out new experiences.
