Research Interests
I have worked on improving the dependability of embedded systems (addressing soft errors in networks-on-chip), of enterprise systems (addressing the predictability of fault-tolerant middleware) and of large-scale distributed systems (addressing operator errors during software upgrades). My doctoral dissertation identifies the leading causes of both planned and unplanned downtime due to upgrades in large distributed systems. I propose novel solutions for mitigating this downtime, and I define a methodology for evaluating the dependability of upgrading approaches.[more information ...]
