I am interested in brain connectivity in health and disease. I have studied functional and structural neural networks in Parkinson's disease, essential tremor, and other neurological disorders. I have also examined the function of the human orbitofrontal cortex. My work applies fMRI, arterial spin labeling, and diffusion tractography. I am also interested in diseases of lymphatic dysfunction and sodium sensitivity.
