Mattia Stival
Researcher (RTD-A) at the Department of Economics, Ca' Foscari University of Venice.
I am currently working as a statistician on the Planet4Health project, collaborating with the Venetian research team under the supervision of Stefano Campostrini and Gaia Bertarelli. My research interests primarily involve the development of statistical models for the analysis of complex data, with a particular focus on time series data and Bayesian methods for social and environmental sciences.
Prior to my work on the Planet4Health project, I served as a post-doctoral researcher at Ca' Foscari University, contributing to the Age-it project for about a year. In this role, I developed statistical models and methods to study multi-morbidity dynamics in Italy.
I got my Ph.D. from the Department of Statistical Sciences at the University of Padova in May 2022. My dissertation, supervised by M. Bernardi and P. Dellaportas, was titled "Sports Performance Analysis with State Space Models". I keep this research theme active by collaborating with experts in the field of sports science.
