Education:

• PhD. Nuclear Engineering, University of Wisconsin-Madison, August 1996

• M.S. Nuclear Engineering, University of Wisconsin-Madison, May 1993

• B.S. Nuclear Engineering, University of Wisconsin-Madison, December 1990

Relevant Work Experience:

• Associate Scientist, Department of Engineering Physics, Fusion Technology Institute, University of Wisconsin, Madison, WI, September 2006-present

• Associate Scientist, Department of Medical Physics, University of Wisconsin, Madison, WI, January 2003-August 2006 (Assistant Scientist Sep. 1999-Dec. 2002)

• Investigated fast neutron fluence, nuclear heating, He production, and damage energy production in various fusion devices including HAPL and ITER

• Designed (using Monte Carlo methods), built, and experimentally tested improved well-type ionization chamber for low energy photon brachytherapy sources (invention disclosure report submitted)

• Modeled and investigated the response of radiation detectors (well ionization chambers, free air chambers, ferroelectric detectors, radiochromic film, CsI digital x-ray detectors/panels, cylindrical and spherical ionization chambers) using Monte Carlo methods

• Modeled and investigated dosimetry for photon and electron emitting brachytherapy sources using Monte Carlo methods (e.g. Pd-103, I-125, Ir-192, Cs-137, P-32, Sr-90)

• Designed, built, and maintained a 24 node Beowulf cluster (now retired) and a 95 node CONDOR computer cluster (part of a 600+ node cluster of clusters)

• Developed and wrote research grant applications (NIH, State of Wisconsin, Industry)

• Assisted and guided faculty/staff/graduate students with Monte Carlo transport, radiation dosimetry, and high performance computing research

• Substitute taught aspects of Monte Carlo methods and Health Physics for Medical Physics/Nuclear Engineering classes (NEEP 602MC, MP569)
