Aging and Methods Laboratory

PI: Huiwen Xu, PhD 

Welcome to the Xu Lab!

Population aging is a major challenge faced by the U.S. health system, with many older adults, especially those with dementia, requiring long term care. To conquer this challenge, Xu Lab applies advanced statistical methods and state-of-the-art machine learning to examine the staffing, quality, disparities, and policies in nursing homes. Our lab is also interested in using AI to improve the methodology and eventually to improve the population health.

Under the leadership of Dr. Huiwen Xu, our lab has published 60+ high quality peer-reviewed articles in leading medical and policy journals such as The Lancet, JAMA Internal Medicine, JAMA Oncology, Journal of Clinical Oncology, JAMA Network Open, JAGS, JAMDA, Health Affairs, Health Services Research, and Medical Care, as well as 2 book chapters and 90+ scientific abstracts. We have established close collaborations with leading universities in the U.S. and beyond. 

News: Dr. Xu has accepted an Associate Professor position from the Nell Hodgson Woodruff School of Nursing at Emory University, starting this August.
