Research

My research interests are mainly in three fields.

Survival analysis. Since 1987, I have been working in this field, in particular on modeling the interval censored data, studying consistency and asymptotic normality of the generalized maximum likelihood estimator (MLE) of survival function or the semi-parametric estimator under linear regression model.
Statistical decision theory. My thesis was on admissibility and minimaxity of the best invariant estimator of a distribution function.
Probability model and computing methods for pattern recognition in the Genome project.
