Research Interests: My research focuses on the synthesis and characterization of novel light-emitting materials. I am involved in several larger research programs involving other scientists from USD and the region. These are:
The Center for Research and Development of Light-Activated Materials (CRDLM)
Photo-Activated Nanoscale Systems (PANS)
Relevent Publications (undergraduates are in bold-face type)
