Dr. Vaida obtained his PhD in Statistics from the University of Chicago in 1998, and after seven years on the faculty in the Department of Biostatistics at Harvard School of Public Health, he joined UCSD in 2004. His research interests are in mixed-effects models, proportional hazards mixed-effects models, and model selection, in particular as they apply to HIV/AIDS and NeuroAIDS studies. Dr. Vaida has published over 70 papers in peer-reviewed journals. Among other projects, he is currently collaborating with the HIV NeuroBehavioral Research Program at UCSD, where he serves as senior statistician on several large multi-center HIV neurobehavioral studies.
Dr. Vaida is the Director of the Biostatistics Module for the CREST and MAS programs at UCSD.
