News

• On our research on invisibility cloaking and electromagnetic wormholes.

• On our research on inverse problems for non-linear hyperbolic equations and in relativity.

• Our collaboration paloDEx has launched a three dimensional X-ray imaging system based on Statistical Inversion (SI). Have a look on its demo on the KaVo Imaging web pages.

Project funded by European Research Council (ERC)

I am the principal investigator of the ERC Advanced grant project Geometric Methods in Inverse Problems for Partial Differential Equations 2023-2028.

Centre of Excellence

I am director of the Finnish Centre of Excellence in Inverse Modelling and Imaging. The status of Centre of Excellence is granted by Research Councli of Finland for the period 2018-2025. This centre continues the Finnish Centre of Excellence in Inverse Problems Research in 2006-2011 and 2012-2017.

Journals

I am editor of journals SIAM Journal on Applied Mathematics, Communications on Analysis and Computation, Research in Mathematical Sciences, and Inverse Problems and Imaging. Submissions to these journals can be done via the web-pages of the journals.
