I am interested in dependability, performance, and security of complex computing systems, with a particular focus on timing behaviour. Within our group we employ a broad range of assessment and evaluation techniques for computing systems and networks, ranging from fault-injection test-beds to simulation and analytical techniques. We develop efficient and accurate modelling and evaluation techniques, applying e.g. Phase-Type distributions in fault-modelling for fault-injection experiments and hybrid discrete-event simulation. We study a large variety of systems, including wireless networks, mobile telephony networks, service-oriented systems, and Computing Clouds.
We conduct extensive statistical analysis of data collected from test beds as well as for medical data.
| Distributed Restart | In this DFG-funded project we investigate the use and impact of the restart method in distributed environments. Through analysis of stochastic models we aim to confirm the fairness property of the restart algorithm and investigate the timing behaviour of network in which several clients employ restart. |
| High-Resolution Clock Synchronisation over Packet-Switched Networks | In cooperation with highstreet technologies we analyse timing behaviour of complex packet-switched networks through detailed simulation using the network simulator ns-2. |
| Efficient Fault-Models for System Evaluation | In cooperation with Prof. Miklos Telek and Prof. Gabor Horvath of the Technical University of Budapest we develop techniques for efficent and accurate stochastic fault-models. We focus on random-number generation from Phase-type and Matrix-Exponential Distributions. This cooperation is supported by the DFG. |
I teach courses on Dependable Systems, Model-based Evaluation of Computing Systems, and Computer Architecture.
Bachelor- and Masters' Thesis Topics
Several topics in the area of performance, dependability and security evaluation are available upon request. These include experimentation and measurement studies, development of stochastic models, measurements in networks and the Cloud and implementation of algorithms.
Memberships
I am member of ACM, IEEE, GI and the GI working group MMB.
