About me

I am a professor in Numerical Analysis at the math department of KTH. The office address is Lindstedsvägen 25, room number 3534.

Research Interests

My research mainly concerns the development of numerical methods for the solution of PDEs. One current specific focus area is boundary integral methods for fluid flows involving particles and drops, and with that both development and analysis of important components such as fast methods to accelerate the computations and numerical quadrature techniques for evaluation of singular and nearly singular integrals.


I am active within the focus area Micro and Complex flows of the Linne FLOW Centre at KTH. This working group is joining researchers at KTH performing theoretical, numerical and experimental work within this exciting field. Our research strategy can be found here.


I am active within the Swedish e-Science Research Center (SeRC) through the core community in Numerical Analysis. In 2012, we initiated a new project in collaboration with the Molecular Simulation community. The project concerns fast methods for electrostatic calculation in molecular dynamic simulations.

Service at KTH:

Vice chair of the department of Mathemtics, KTH, since January 2020.

Head of the division ofNumerical Analysis (part of the Mathematics department), KTH,  2011--

Member of KTHUniversity Board, May 2013- April 2020.

Member of KTHFaculty Council, April 2015- June 2019.

Service to the community:

Member of the program committee (PC) for International Congress of Mathematicians (ICM) 2022. Citation from in the PC was not made public until the Opening Ceremony of the ICM 2022. The reason for this secrecy was to protect the members of the committee from personal or political pressure from outside. Invitations to lecture at the International Congresses carry such high prestige that individuals or groups have always made efforts to influence the decisions of the committee.
