Junior Bernard Wittmaack, ‘11, traveled to San Juan, Puerto Rico this fall to present a talk on his research at a meeting of the American Chemical Society. Bernard studies halogen bonding in group 14 halomethane analogues with chemistry professor Kelling Donald, using computational chemistry techniques. The two have performed intensive calculations using a supercomputer cluster here at Richmond, and expect to publish their work soon. Bernard is majoring in interdisciplinary physics with a chemistry concentration, allowing him to combine courses from both disciplines.
