Academic Research Associate at Institute of Statistics of the Pontificia Universidad Católica de Valparaíso, Chile. In August 2006, I completed my doctorate degree in Statistics at University of São Paulo, Brazil under the direction of Dr. Gilberto A. Paula.
My research interests lie in the fields of sensitivity and influence diagnostics as a mean to criticize and to improve the statistical modeling. In particular, I focus on the development of estimation and influence procedures in mixed-effects models and longitudinal data under non-normal distributions as well as the computational implementation of such techniques.
