She is principal investigator of two research projects funded by the German research council and teaches courses on performance analysis of communication systems and dependability evaluation. Prior to her current position, she was a visiting researcher at Hewlett-Packard Labs in Palo Alto, CA, USA. Her research interests include dependability evaluation of service-oriented architectures and wireless computer networks, as well as stochastic models for representing data in those systems and stochastic models for improving dependability through restart-based techniques.
