Interests

My research interests revolve around understanding how lymphatic circulation is involved in regulating tissue sodium, protein, and fat accumulation in human health and disease. To this end, I have worked to improve magnetic resonance imaging (MRI) methods for measuring lymphatic vascular function and sodium in the body noninvasively. I'm also interested in the biological basis of sodium MRI signal, and related MR relaxometry (T2 and T1rho) and spectral imaging methods including chemical-exchange saturation transfer (CEST) MRI.

Projects

My research is focused on improving the lives of patients with understudied diseases of the lymphatics. My current research projects seek to provide noninvasive molecular MRI tools to address clinical needs for 1) objective diagnostic criteria for lipedema, 2) risk assessment for lymphedema and fibrosis secondary to lymph node removal, and 3) radiologic markers of salt sensitive blood pressure. The relevance of lymphatic insufficiencies to portend risk for obesity and salt-sensitive hypertension is also being explored in pre-clinical and clinical studies.

These research projects are carried out in collaboration with scientists and physicians within the VUIIS Center for Translational Vascular and Physiological Imaging, VUMC Radiology, Vanderbilt Dayani Center for Health and Wellness, Vanderbilt-Ingram Cancer Center, Vanderbilt Heart and Vascular Institute, and Vanderbilt Translational and Clinical Cardiovascular Research Center.

I'm interested in collaborating to test emerging lymphatic therapies that may benefit from noninvasive imaging measures of improvements in tissue health.
