I have research projects in progress in the following areas:
The primary instrument used in our spectroscopic work is a very high spectral resolution, high sensitivity, absorption spectrometer that works in the region of 1600 nm. Its light source is an external cavity diode laser. At present we use a multipass Herriot cell to study pressure broadening effects on overtone infrared lines. This work is carried out in collaboration with Professor Stephanie Schaertel.
The mass spec project began in January 2007. The instrument can use either gaseous samples or solid samples by laser desorption and ionization. The next phase is to develop methods of space focusing, to improve the resolution limit caused by the finite spatial volume of ion creation.
Students with interests in computational work and computer programming may enjoy computational projects. These projects involve both electronic structure calculations and dynamics and kinetics calculations that describe the motions of the atoms during collisions and reactions. We use both classical and quantum mechanical models. For the calculations we use the computational cluster in the chemistry department and national supercomputer facilities. Several projects involve collaborations with experimental and theoretical research groups around the world. One current computational project is a study of the quenching of electronically excited oxygen in the atmosphere.
I am currently away on sabbatical and will return mid-August 2013.
I also enjoy playing pool. The photograph at left was taken by Bernadine Carey-Tucker for a piece in Grand Valley Magazine.
Imsim, and its accompanying image fitting program (never released publicly) have returned to active development as of August 2008 after a dormant period of several years. If you are interested in them, please contact me by email so I can let you know about recent developments.
