Dr. Kumarappan is one of the key researchers involved with The Atomic, Molecular and Optical (AMO) Nebraska and Kansas NSF EPSCoR Track 2 project Collaborative Research: Imaging and Controlling Ultrafast Dynamics of Atoms, Molecules, and Nanostructures. His main research focus is to develop methods to align and orient small molecules in the gas phase, and to study ultrafast physics in the molecular frame.
During his presentation, Dr. Kumarappan conducted several demonstrations illustrating both sound and light wave behavior under a variety of conditions. The participants were fascinated with the experiments and actively participated in the discussion.
Once the EXCITE participants had a general idea of wave behaviors, Dr. Kumarappan led the group on a tour of the James R. Macdonald Atomic, Molecular and Optical Physics Laboratory and showed the participants the intricate workings of a complex laser system. He then explained his research, emphasized connections to his previous presentation and provided concrete examples to illustrate his scientific methods for addressing his research questions.
