| SUMMARY OF RESEARCH:
As an undergraduate student at the University of Alabama in Huntsville,< I was a laboratory assistant employed by thePhysics Department to work in N.A.S.A.'s Magnetospheric Branch at the Marshall Space Flight Center. There I worked with others in developing a list of calibration constants to be used on data from the retarding ion mass spectrometer aboard the Dynamic Explorer 1 satellite. This data was used by researchers worldwide to study the ion concentrations in the magnetosphere and plasmasphere.
During my First year as a graduate research assistant at Purdue University, I assisted in the development of a scintillating fiber charged particle tracking system to be used in the D0 experiment at Fermi National Laboratory. One of my specific tasks was to study the requirements of the high density scintillating ber to waveguide fiber connectors needed for the construction. I developed and produced a prototype design for such a connector. I also studied the effects of radiation on some of the adhesives and composite carbon fiber materials to be used in the detector's construction, and I assisted in the study of precision placement of ribbon-like scintillating fiber assemblies onto carbon fiber cylinders.
In the summer of 1994, I became a member of the Purdue group at Cornell's CLEO particle detector. My original work in that group included a study of the dE/dx particle identification method used at CLEO. I was in charge of the upkeep of calibration constants used for this identification method, and I worked with others at CLEO to investigate and better understand various aspects of the dE/dx identification being used.
My thesis research was also conducted during this time. It involved the study of about 145,000 decays of the tau lepton into three charged pions and a tau neutrino. The decays were collected by the CLEO particle detector. I was able to fit the complicated substructure in the decay to a model involving 9 complex fitting parameters, producing a satisfactory description of the decay. I was also able to use information involving the pseudoscalar component in the decay to help place a lower bound on the average of the up and down quark masses as they appear in the QCD Lagrangian.
For the summer of 2001, I have been hired as a post-doctoral research associate by Purdue University so that I may complete a paper involving my thesis research.
