• ICT

My most recent research area is Information and Communication Technology. One topic of interest is how to measure characteristics of a packet-switched communication network (such as the Internet) and its traffic, having access only to systems on the edge of the network, not assuming any prior knowledge about the internal structure.
One result of this research is a method for estimating available bandwidth: BART (Bandwidth Available in Real-Time) .

Some of the public research projects in which I have been active in this area are

Evergrow (supported by the European Union)
Ambient Networks (supported by the European Union)
Moment (supported by the European Union)
Center for Networked Systems (supported by the Swedish agencies Vinnova, KKS and SSF)

I was a scientific advisor for the research programme
Winternet (supported by SSF)

During several years I was a member of the steering committee of the conference
SNCNW

This research was funded primarily through my previous affiliation with Ericsson Research.

• physics

Another research area, which for the past several years has been pursued at a very low intensity, is physics, especially elementary particle physics. I am interested in the quark-quark interaction, and how it may manifest in nucleons, in high-energy particle collisions and in the astrophysical/cosmological QCD plasma.
