David Powell, PhD.
PhD, Adjunct Professor in
Biomedical Engineering, University of Kentucky. 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.
My research interests include:
· Alzheimer’s Dementia
· traumatic brain injury
· magnetization transfer
· diffusion tensor
· preoperative fMRI &
