Researcher
Ralitza Gueorguieva serves as a Senior Research Scientist in Biostatistics and Director of Biostatistics in Psychiatry at Yale University School of Public Health, where she has been a faculty member since 2000. She holds primary appointments in the Department of Biostatistics and collaborates extensively across multiple Yale research centers including the Center for the Translational Neuroscience of Alcoholism, Yale Tobacco Center of Regulatory Science, and the Yale-BI Biomedical Data Science Fellowship program. PhD in Statistics from University of Florida (1999) MSc in Statistics from University of Florida (1996) MSc in Informatics from Sofia University (1994) Dr. Gueorguieva specializes in developing and applying advanced statistical methodologies for psychiatric research, with particular expertise in longitudinal data analysis, mixed and mixture models, tree-based methods, and nonparametric alternatives. Her research focuses on methodological development for analyzing complex psychiatric data, including models for longitudinal outcomes of different types, risk assessment screening algorithms, and joint analysis of longitudinal and survival outcomes. She has established significant collaborations with psychiatric researchers across numerous clinical domains including tobacco research, alcoholism, substance abuse, depression, anxiety disorders, eating disorders, women's behavioral health, schizophrenia, bipolar disorder, OCD, and PTSD. Her recent publication portfolio demonstrates strong continuity in applying sophisticated statistical approaches to mental health and addiction research, with a notable emphasis on substance use patterns among youth, binge-eating disorder treatments, tobacco product regulation, and predictive modeling in psychiatric contexts. The breadth of her work spans methodological innovation in statistical techniques to direct applications in clinical trials and observational studies. Certificate of Appreciation as Top 10 Reviewer for Biological Psychiatry (2011 and 2007) International Biometric Society's Eastern North American Region (ENAR) Student Award (1999) First place, Student Abstract Competition, Annual Florida Epidemiology Meeting (1998) Statistics Faculty Award for Outstanding Senior Graduate Student, University of Florida (1998) Dr. Gueorguieva maintains active advisory roles with Biological Psychiatry (2007-present), NIMH (2004-present), Journal of the Royal Statistical Society (2007-2010), and National Science Foundation (2009). She is the author of the influential book "Statistical Methods in Psychiatry and Related Fields: Longitudinal, Clustered and Other Repeated Measures Data" (2017), which serves as a key resource for researchers applying advanced statistical methods to psychiatric data. Her research lab focuses on Statistical Methods in Psychiatry and Related Fields, with particular attention to longitudinal and clustered data analysis.
