Dr. Zhu is a biostatistician at ARG with expertise in alcohol and tobacco epidemiology, mortality analysis, and causal inference methods. Her research has examined socioeconomic status as a key modifier in alcohol-related disease mortality and investigated substance co-use patterns using diverse national datasets including NHIS, NSDUH, and NHANES. She has extensive experience with advanced statistical techniques including causal mediation analysis, survival analysis, moderation analysis, and simulation modeling, and has led studies on alcohol screening in primary care patients and telehealth utilization among heavy episodic drinkers during COVID-19.
