Research Activities

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.

Projects

HyperStar A tool for fitting phase-type distributions to empirical 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.

Collaboration

We collaborate among others with

  • Leila Kloul, University of Versailles, France (funded by the Center for International Cooperation, FU Berlin)
  • Miklos Telek, Technical University Budapest (funded by DFG)
  • Gabor Horvath, Technical University Budapest (funded by DFG)

 

Teaching Activities

I teach courses on Dependable Systems, Model-based Evaluation of Computing Systems, and Computer Architecture.

Bachelor- and Masters' students

If you write a thesis with me, please provide me with a copy of the letter indicating your deadline. You may use the latex-template for writing your thesis.

 

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. Modelling related topics are in the area of queueing models with negative customers and phase-type fitting.
