Degrees

  • Ph.D. in Physics, Louisiana State University, Baton Rouge, Louisiana, 1987.
  • M.S. in Physics, Louisiana State University, Baton Rouge, Louisiana, 1985.
  • B.A. in Mathematics (major), Physics (minor), Francis Marion University, Florence, South Carolina, 1983.

Research Interests – Experimental Laser Physics

I am interested in many aspects of laser spectroscopy and laser design. My past work has included the following:

  • Design and construction of numerous laser systems, including an open-cavity helium neon laser, a nitrogen laser, a diode laser, and a grazing-incidence dye laser
  • Construction of a Cesium heat pipe, heat pipe temperature controller, ionization detection circuit, and computer-interface module
  • Resonance ionization spectroscopy and multiphoton ionization spectroscopy on Cesium using a Nd:YAG-pumped dye laser system
  • Diode laser fluorescence spectroscopy and saturated absorption spectroscopy on Rubidium
  • Grazing-incidence dye laser performance as a function of grazing angle, pump laser intensity, dye concentration, and dye solvent.
  • Experiments on polarization characteristics, transverse electromagnetic modes, and resonator stability in an open-cavity helium-neon laser.
  • Design and construction of an optical detection system, photomultiplier tube housing, and scanning system for a monochromator.

Affordability

FMU has the lowest cost of attendance of any college in South Carolina, based on rankings from CollegeFactual.com.

Meaningful Academics

The liberal arts remain the foundation of a great education for all FMU students, but we’re developing high-caliber professional programs to meet the 21st century needs of both our students and our community.

The Right Size

No giant lecture halls here. We keep class sizes small and the crowds thin at FMU because that’s the environment that best facilitates learning. A 15:1 student-professor ratio, and right about 4,000 students sound like “just right” numbers to us.

Aesthetics

Students can walk our lovely, tree-lined campus in 20 minutes, but most take longer because in a place this pretty, you have to stop and enjoy nature’s beauty.

UNIVERSITY HONORS

Francis Marion University has been recognized for five straight years as a “Great College to Work For” Honor Roll university by the Chronicle for Higher Ed. More at http://www.chronicle.com/interactives/greatcolleges16

FMU is consistently ranked among the Best Regional University by U.S. News and World Report.

Francis Marion University is in ETC’s top 10 percent of university’s that have the most impact on graduate’s long-term career earnings. More at www.educatetocareer.com.
