I entered the medical imaging community in 2001 after completing a PhD in Solid State Physics at the University of Kentucky. I have worked at the MRISC, Magnetic Resonance Imaging and Spectroscopy Center, at the University of Kentucky since 2001 as a systems specialist and MRI physicist helping with analysis, protocol development, equipment integration and systems administration.
