Sharon Xiangwen Xie, PhD

Dr. Xie’s current research goals are twofold. First, she continues to develop new statistical methods for survival analysis, missing data, measurement error problems, high dimensional data, biomarker evaluations, and longitudinal analysis in response to methodological problems that arise in her collaborative work in the research of neurodegenerative diseases (e.g., Alzheimer’s disease, Parkinson’s disease, frontotemporal dementia, amyotrophic lateral sclerosis) and in other collaborative research. Second, she continues to study the epidemiology of neurodegenerative diseases and translate her novel statistical methods into real world applications. Dr. Xie’s research has been continuously funded by NIH grants where she serves as principal investigator. She is the director and principal investigator of the biostatistics and data management core for three NIH-funded neurodegenerative disease research centers/program project grants: the Alzheimer’s Disease Research Center, Center on Alpha-Synuclein Strains in Alzheimer’s Disease and Related Disorders, and the frontotemporal lobar degeneration program project grant. Please see Sharon Xie’s Research Lab Website for additional details about her team members and research.

Dr. Xie serves as Deputy Director for the Center for Clinical Epidemiology and Biostatistics. Dr. Xie is an elected Fellow of the American Statistical Association. She is currently an Associate Editor of Alzheimer’s & Dementia. She was the program chair for the Biometrics Section of 2019 Joint Statistical Meetings. She is a former chair of the National Institute on Aging Alzheimer’s Disease Center Data Core Steering Committee. She has served as an elected standing member of the Parkinson Study Group Scientific Review Committee (2016 – 2019) and the National Alzheimer’s Coordinating Center (NACC) Scientific Review Committee for the National Institute on Aging (2015-2019). She is currently a standing member for Neurological Sciences and Disorders B Study Section (NSD-B) of National Institute of Neurological Disorders and Stroke.
