Morris specializes in using kinetic modeling and image processing to extract physiological information from dynamic PET images. His current projects include:
Modeling and texture analysis to image Non-small cell lung cancer with tyrosine kinase inhibitor tracers
Novel kinetic modeling to image dyskinesias in Parkinson's
Continued Optimization of Dopamine Movies to study Addiction and Behavior
Applying principles in functional connectivity and machine learning to analyze dopamine movies
Imaging new targets in Depression, Alcoholism
Morris and his group continue to refine mathematical and statistical aspects of their techniques for making "dopamine movies" of the brain. With their dopamine movies, Morris and colleague Kelly Cosgrove and their team discovered sex differences in brains of smokers smoking cigarettes (J Neurosci Dec 10, 2014).
