Ana Paula Martins is an Associate Professor at the Department of Mathematics of University of Beira Interior (UBI). Additionally, she is a member of the Centre of Mathematics and Applications, a prominent research unit in Mathematics and Applications affiliated with UBI. She earned her Ph.D. in Mathematics from UBI in 2005, building upon a strong academic foundation with a Master's degree (2002) and Bachelor's degree (1998) in Applied Mathematics from the University of Coimbra. Since completing her Ph.D. with a focus on Probabilistic Extreme Value Theory, she has consistently demonstrated a keen interest in the stochastic modelling of extreme values. Her research is particularly centered on the measurement and modelling of multivariate and spatial dependence in extreme events. Beyond her core focus, she has actively collaborated on research endeavours in diverse scientific domains, contributing to the statistical analysis of data within Health Sciences and Psychology.
