Research Interests

Radionuclide applications, including the study of cosmogenic nuclides and accelerator based Surface Layer Activation for studying wear in mechanical systems. Currently investigating evidence of supernovae or gamma ray bursts in excursions in cosmogenic nuclide production to see whether such events might have been responsible for global extinctions. Also applying SLA to wear in biomedical implants. If you would like to know more about the technique of Surface Layer Activation, click here.

Collection of bone fragments and jaw bones with teeth in them.


Representative fossils collected from Tunica in 2004, added to the Audubon collection now at Louisiana State University.


Person removing soil from steep bluff along a quiet stream, with bright sunlight through the heavy forest overhead.



Dr. Ken Duffy, collecting soil samples for cosmogenic nuclide measurements from late Pleistocene loess deposits along Tunica Bayou north of St. Francisville, Louisiana.




In previous research, I have applied automated gamma ray spectrometry configurations to gamma backscattering for nondestructive inspection of welds, composite materials, and even Space Shuttle tiles.  If you would like to know more about this approach, please click here.

Past work also includes applications of ion beam microtextured metals to thermophotovoltaic (TPV) power sources, to ultracapacitor electrodes (funded by NSF), and for controlling optical properties.



This work also relates to nanotechnology and surface chemistry. Most of it has been performed in collaboration with the Ion Optics Corporation of Waltham, Massachusetts, a company specializing in ion beam modifications of metal surfaces to control infrared absorption and emission. For more information about our TPV testing, please click here.

I also am continuing to follow recent work on deep inelastic electron scattering in heavy nuclides, particularly single nucleon knockout to 700 MeV, particle track etching in dielectrics, particle interactions and radiation corrections. Some of this work may have implications for cosmology and astrophysics.

Prior Experience

1984-1994: SPIRE CORPORATION, Senior Scientific Staff.

Mgr., Radionuclide Devices. Contract research, some federally funded, primarily involving studies of wear, erosion, or corrosion using Surface Layer Activation. Also, modeling and accelerator experiments with new radiation damage resistant photovoltaic cells making high energy-density long-lived radionuclide batteries. USASSDC optical materials program developing rugged baffle materials for space-based telescopes using ion beam micro-texturing of metals and some optical scatter modeling to predict texture effects on broadband light absorption. Helped test lead carbonate scintillator detector crystal growth, metallized polymer films to form hot-dome anemometers, microchannel plate amplifiers by particle track etching, and gas microstrip detectors on conductive polymers.
