Catalogo dei Corsi di studio

Professor Geraci obtained a Laurea (MSc) magna cum laude in Economics from the University of Sassari (Italy) in 2000 and a PhD in Applied Statistics from the University of Florence (Italy) in 2005. He carried out academic research in several institutions, including the National Council of Research (Italy), the University of Manchester (UK), University College London (UK), and the University of South Carolina (USA), where he currently holds an appointment as Adjunct Professor of Biostatistics. His research interests include statistical methods and applications for health sciences, quantile inference, random-effects models, multivariate statistics, missing data, statistical computing, programming (R and C/C++), spatial statistics, accelerometer data, epidemiology, and pediatrics.

Professor Geraci is involved in various collaborations in methodological and applied research. He has published peer-reviewed articles in statistics, cancer epidemiology, maternal and child health epidemiology, physical activity (accelerometry data), gastroenterology, nuclear medicine and higher education. He also authored four statistical R packages on CRAN. He received funding awards for both methodological and collaborative research projects including a major Center grant (NIH P20) for 11 million dollars as lead of the Statistical and Data Management Core, several methodological grants (e.g., NIH R03 and intramural funding) as principal investigator for thousands of dollars, several collaborative grants (NIH R01 and R03) totalling 10 million dollars as co-investigator and lead statistician.

In 2010, Professor Geraci was awarded Chartered Statistician by the Royal Statistical Society. He obtained the National Scientific Habilitation (Abilitazione Scientifica Nazionale) as Full Professor of Statistics in 2017 (settore concorsuale 13/D1) and as Full Professor of Medical Statistics in 2019 (settore concorsuale 06/M1). He was Statistical Editor for the Journal of Child Health Care (SAGE), Associate Editor for the Journal of Applied Statistics (Taylor & Francis), and Associate Editor for Statistical Methods and Applications (Springer). He is currently a Board Member of Significance (Wiley on behalf of the Royal Statistical Society RSS and the American Statistical Association ASA). He is an RSS fellow since 2006 and ASA member since 2015. He performed more than 350 reviews for 62 distinct journals (verified on Publons) including the Journal of the American Statistical Association, Journal of the Royal Statistical Society A, Journal of Statistical Planning and Inference, American Sociological Review, Annals of Applied Statistics, Journal of Statistical Software, Scandinavian Journal of Statistics, Statistical Methods in Medical Research, Statistics and Computing, Statistics in Medicine, as well as journals from the Lancet group. He has been awarded Publons Top 1% Reviewers for multidisciplinary (2017) and cross-field (2019).
