Current position at VTT
Research professor, Stochastic systems
Research background and current research topics
Probability theory in many flavours and application contexts:
reliability theory: dependent components, network reliability
point processes: martingale dynamics
queueing theory: queues in communication devices and systems
Gaussian processes: Gaussian teletraffic modelling, fractional Brownian motion
random graphs: power-law graphs as models for large networks
stability of Markov processes: analysis of peer-to-peer algorithms
stochastic geometry: fractality of population distributions, spatial
statistics: analysis of teletraffic, road traffic accidents, electricity
