Niklas Carlsson

Senior Associate Professor

Niklas Carlsson works in the general area of distributed systems and networks. His research aims at providing system insights and solutions that help deliver tomorrow’s services both effectively and securely.

Niklas Carlsson is an Associate Professor at Linköping University, Sweden. He received his M.Sc. degree in Engineering Physics from Umeå University, Sweden, and his Ph.D. in Computer Science from the University of Saskatchewan, Canada.

He has previously worked as a Postdoctoral Fellow at the University of Saskatchewan, Canada, and as a Research Associate at the University of Calgary, Canada.

His research interests are in the general area of distributed systems and networks, but his research often encompasses many other research domains.  Recent research interest include among other things: (i) how to best deliver tomorrow’s interactive streaming and mixed reality experiences, (ii) network security, and (iii) characterization and modeling of underlying fundamentals such as the popularity dynamics within large-scale systems.

To better understand existing technologies and develop and evaluate new better technologies, his research includes a combination of analytic modeling, simulations, measurement-based characterization, data analytics, machine learning, system implementation, as well as real-world experiments. He has a particular interest in trying to obtain solid fundamental/general insights towards the best possible performance, scalability, efficiency, and/or quality of service. When possible, analytic lower bounds are developed for the purpose of rigorous protocol and system evaluation.
