CURRENT RESEARCH ACTIVITY

My current research interest is focused on Dependable systems. I am focusing in last years on software aging phenomena in web environments. However, I have started to work on merge Dependability and Performance models to maximize the resource usage maintaing the availability of the systems. Furthermore, I am also interested on Green Computing from the middleware perspective.
