Professional profile

I am  a teacher and a mentor who  enjoys research. My interests have evolved over the years:  I  started in nonparametric inference and asymptotic methods in statistics,  while today my research encompasses stochastic modeling and inference, mainly in biology and medicine (ecology, epidemic studies, genetics).  Presently,  I use non homogeneous Poisson and birth-death processes (some related to ODEs) for modeling real life phenomena; the final aim is to propose and study estimation (inference) methods that try to address some challenges in the available data (never perfect).
