Faculty & Staff

Physics Department faculty seek to present each of their students with a clear and cohesive picture of what the study of physics entails, and what makes Gettysburg outstanding among college physics programs.

Each faculty member serves to enable students to actively assume responsibility for and control of their studies with thorough information about what demands, opportunities, and rewards to anticipate here and after graduation. 

"We find them smaller and fainter, in constantly increasing numbers, and we know that we are reaching into space, farther and farther, until, with the faintest nebulae that can be detected with the greatest telescopes, we arrive at the frontier of the known universe." -Edwin Hubble
