Areas of Interest: 

My research interests are in the areas of survival analysis and counting processes. I am particularly interested in non- and semi-parametric models and their applications to analyzes of multi-state models and clustered failure time data. Models of this kind arise in medical follow-up studies, as well as many other areas such as demography, epidemiology, econometrics and engineering.
