My teaching responsibilities include courses for students majoring in physics, as well as courses for non-physics majors, such as chemists, biologists and pre-med students. A list of courses that I have taught can be found here.
My research interests concentrate on theoretical and computational physics, particularly in the area of Atomic, Molecular and Optical (AMO) Physics. This work is currently sponsored by the United States National Science Foundation (NSF) under grants PHY-1430245 and PHY-1520970. These grants allow for extended collaborations with other research groups in North America, Europe, and Australia. In addition, our group enjoys extensive supercomputer support through the eXtreme Science and Engineering Discovery Environment (XSEDE) program of the NSF.
Research participation by undergraduates is sponsored through the REU (Research Experience for Undergraduates) program of the NSF. Example projects (to be updated soon) include:
- Generation of Mathematica animations to show the charge distribution of collisionally excited states. Click here for details.
- Excitation and ionization of atomic hydrogen by electron impact within the Temkin-Poet S-wave model. Click here for details.
- Excitation, dissociation, and ionization of H2+ by a strong laser pulse. Click here for details.
- Ionization of atomic hydrogen by strong infrared laser fields. Click here for details.
I have co-authored the book Polarization, Alignment, and Orientation in Atomic Collisions (Springer, New York, 2001; 1st edition in 2001, 2nd edition in 2017) and edited the book Computational Atomic Physics: Electron and Positron Scattering from Atoms and Ions (Springer, Heidelberg, 1996).
My service activities have involved numerous committees at Drake University, including two terms as President of the Drake Faculty Senate. Outside of Drake, I serve as referee for many professional journals and grant agencies in the United States, Canada, Germany, the UK, and Australia. I was the Secretary of the International Conference on Photonic, Electronic, and Atomic Collisions (ICPEAC) from 2001-2007 and a member of their Executive and General Committees from 1991-1995, 1999 – 2007, and 2015-2017. From 1998 – 2000, I chaired the Theoretical Atomic and Molecular Community (TAMOC), a forum for communication among AMO theorists and with the AMO community at large. The group is recognized by the American Physical Society (APS) within the Division of Atomic, Molecular, and Optical Physics (DAMOP). From 2006 – 2010, I served as the Treasurer of the Gaseous Electronics Conference (GEC).
I organized the 68th Gaseous Electronic Conference as a joint meeting with the 9th International Conference on Reactive Plasmas (ICRP). The meeting was held Oct. 12-16 in Honolulu (Hawaii). Click here for details.
