Present
Teach undergraduate courses in physics, mathematics, and
statistical analysis. Present
classroom material through lecture, demonstration, and simulation; direct
laboratory experiments; assess student performance; offer regular study
sessions; and assist students on an individual basis. See Why I Teach
in Kentucky Wesleyan Today.
Courses include Introduction to Engineering, Computer Graphics/Communication,
Statics, Design of Logic Circuits, Introduction to Physics in Modern
Medicine, Physics and the Arts, Introductory General
Physics I and II, General Physics I and II, Mechanics,
Electricity and Magnetism, Electronics, Modern Physics,
Probability and Statistics, Statistics in the Behavioral
Sciences, Statistical Analysis, College Algebra and
Trigonometry, Differential Equations, and Partial Differential
Equations. See My
Courses for course listing.
Serve as academic advisor to pre-engineering and physics
students. Serve as faculty advisor
to the student chapter of the Kentucky Society of Professional
Engineers. Designed the general
physics and advanced physics laboratories in the Yu Hak Hahn Center for
the Sciences. Developed
PC-interfaced laboratories which allow students to perform real-time data
acquisition experiments in classical and modern physics. Maintain the
physics laboratories. Serve on
college committees. Developed
statistical models in SPSS and SYSTAT to assess the effectiveness of the
General Education Program and to award high-achiever scholarships.
Visiting Professor of Physics – University of Kentucky – 2008 to 2009
On leave during the 2008/2009 academic
year to the
University of Kentucky training
in new teaching technologies and participating in nuclear physics
research. Delivered lectures, simulations,
and demonstrations on general physics to large student audiences;
utilized an audience response system to engage students; employed
multiple projection systems to deliver content and do problem solving;
developed online homework assignments with WebAssign; maintained an
online course website and gradebook; and delivered web-based recitation
sessions utilizing Adobe Captivate.
Involved in computational analysis for the MuLan Collaboration
which reported in 2007 a muon lifetime of τμ =
2.197013(24) microseconds utilizing µ+ decay data taken at the
Paul Scherrer Institute in Switzerland.
The MuLan team was working to reduce the uncertainty to 1-2
ppm. Developed programs in C++ and
ROOT to analyze and determine the zero time calibrations for the 170
detectors utilized in the MuLan experiment, and then characterized the
statistical distribution of coincidences between all detectors.
Medical Physics Fellow – Vanderbilt University School of
Medicine – 1999 to 2000
On leave during the 1999/2000
academic year
to the Vanderbilt University Medical Center focusing on clinical
radiation therapy and participating in dosimetry research. Involved in the development of 3-D
treatment plans for cancer patients as well as the operation and testing
of the linear accelerators used to deliver radiation treatments. The dosimetry research involved
measuring the dosimetry parameters for the Implant Sciences I-Plant 3500
Iodine-125 radioactive treatment seed source. The I-Plant 3500 seed was characterized
at Vanderbilt for use in brachytherapy treatment including the treatment
of prostate cancer.
Assistant Professor of Physics – Brescia College – 1994 to 1995
Taught undergraduate
courses in physics, mathematics, and electronics. Presented classroom material; directed
laboratory experiments; assessed student performance; and tutored
students on an individual basis.
Served as academic advisor to physics minors and pre-engineering
students. Maintained the physics
laboratories and the reflecting telescope observatory. Developed PC-based laboratories which
allowed students to perform real time data acquisition experiments in
classical and modern physics.
Graduate Research Assistant – University of Kentucky – 1989 to
1994
Developed the DISPLAY
workstation-based data acquisition and analysis system which allowed
scientists to control nuclear physics experiments, acquire and process
experimental data, and perform various statistical and numerical
analyses. Developed the
applications software to allow scientists to control the experimental
setup, acquire particle tracking information, acquire gamma‑ray
data, process the data into meaningful spectra, display the spectra on
several graphic interfaces, and perform various statistical and numerical
analyses. Performed two large
scale nuclear muon capture experiments at TRIUMF in Vancouver, B.C. to
examine the nuclear structure of five light nuclei - 19F, 23Na,
27Al, 31P, and 35Cl. Utilized a novel experimental technique
to measure the hyperfine capture rates following muon capture to each of
the five nuclei, in order to test the Partially Conserved Axial Current
(PCAC) hypothesis.
