Research interests

The general theme of my research is the study of point-defects in insulating materials using luminescence methods.  We are developing and refining the use of time-resolved analysis for investigation of the physical processes responsible for the emission of luminescence in materials.  The work is of interest and may find application in radiation- and retrospective-dosimetry.    The materials of interest in this study are quartz, a ubiquitous natural mineral, and a-Al2O3:C, a highly-sensitive synthetic dosimeter. 

Another thread to the research is the use of thermally and conventional optically stimulated luminescence to study point-defects and luminescence processes in quartz, a-Al2O3:C and orthopaedic grade ultra-high molecular weight polyethylene, a thermoplastic used in prostheses.  I am also interested in the complementary use of time-resolved optical stimulation and positron annihilation spectroscopy to investigate defects involved in the luminescence process in materials.  

Experimental investigations of both optical and thermal stimulation methods are complemented by parallel programs on development of theoretical and numerical models of luminescence.
