Dr. Wanzhu Tu is an investigator funded by the National Institutes of Health. He has developed a new set of semiparametric modeling techniques for the dissemination of multiple nonlinear and interacting influences of factors in the renin-angiotensin-aldosterone system (RAAS) on blood pressure. His research team has generated a number of important findings that characterize a unique pathophysiology of hypertension in African Americans. He is a fellow of the American Heart Association.

Dr. Tu is a statistical methodologist with an interest in semiparametric regression. His recent methodological work has appeared in both theoretical and applied statistical journals, including Journal of the American Statistical Association, Biometrics, Journal of the Royal Statistical Society, and Annals of Applied Statistics.

Featured Projects

Novel biomarkers as a clinical tool for excessive alcohol use screening

(RO1 NIH/NIAAA)

Role: Co-Investigator

Excessive alcohol use is an emerging health concern. Previous studies have found serum and urine markers that reflect cellular responses to alcohol exposure. We seek to use these mechanistically derived markers to screen excessive alcohol use disorder.

Alcoholic Hepatitis Network Data Coordinating Center

(U24 NIH/NIAAA)

Role: Co-Investigator

The Data Coordinating Center supports a major clinical trial on the treatment of alcoholic hepatitis. We also support an observational study on the natural history of the disease.
