Finnish Workshop on Radiative Transfer – connections across disciplines
May 10th 2019
The first Finnish Workshop on Radiative Transfer was organised jointly by Finnish Meteorological Institute, University of Eastern Finland and University of Helsinki in Helsinki 6–7 May, 2019. National experts on computational modelling and theory of radiative transfer gathered together to present their research and exchange ideas on their work applied to the atmosphere, biomedical optics, vegetation, snow, and astronomical objects. The aim of the workshop was to connect Finnish researchers across scientific disciplines and to create a community for future collaboration in joint projects and enhanced researcher mobility.
“Advanced modelling framework and fast solutions are crucial in the quickly developing field of atmospheric remote sensing”, says Hannakaisa Lindqvist, organiser of the workshop at FMI-SPACE. “For example, new satellites produce increasing amounts of data that benefit from efficient algorithms,” Lindqvist describes the FMI interests in the workshop. Prof. Tanja Tarvainen, organiser of the workshop from the University of Eastern Finland, emphasizes the importance of collaboration: “We wanted to bring together radiative transfer researchers to advance collaboration and build networks especially for the young generation of researchers.” The workshop finished with a visit to the scattering laboratory at the University of Helsinki. “Measurements involving the scattering and absorption of light by complex media have tremendous value in giving the ground truth reference to our computational models,” concludes Antti Penttilä, workshop organiser from University of Helsinki.
Finnish Workshop on Radiative Transfer was attended by 23 invited participants from the Finnish Meteorological Institute, University of Helsinki, University of Eastern Finland, VTT, University of Oulu, and the Finnish Geospatial Research Institute. The next workshop will be arranged in spring 2020 at the University of Eastern Finland, Kuopio.

Centre of Excellence of Inverse Modelling and Imaging
June 1st 2017
The Academy of Finland has selected 12 new Centres of Excellence (CoEs). The first stage of the call attracted a total of 179 letters of intent, and 34 applicants were invited to the second call stage to submit full applications. The operating period of the new CoEs is longer than before, eight years (2018–2025), which according to the Academy of Finland will further serve to support scientific risk-taking.
This is the third time the Centre of Excellence of Inverse Modelling and Imaging was selected to the CoE programme. The Centre of Excellence of Inverse Modelling and Imaging is coordinated by the University of Helsinki, and it comprises a large number of research groups in the field of inverse problems research from several Finnish universities.
UEF’s Inverse Problems Group is based at the Kuopio Campus, comprising four professors and some 20 researchers. Traditionally, UEF’s research group has been the largest one in the CoE. The UEF Inverse Problems Group is led by Professor Jari Kaipio.
Inverse problems research is a field of applied mathematics, which seeks to develop computational methods for medical tomography imaging, non-destructive testing, astronomy and environmental modelling. The UEF Inverse Problems Group focuses on modelling-related uncertainties in particular, as well as on applications in the fields of medicine and sufficiency of natural resources.
The research group is also strong in technology transfer, as the group’s researchers have established several companies, such as Numcore, Rocsole, Kuava and Ownsurround in the Kuopio region, and they have also won several national and international prizes.

Funding for research on photoacoustic imaging from Jane and Aatos Erkko Foundation
June 10th 2016
Docent Tanja Tarvainen has been awarded a grant of 500 000 euros by Jane and Aatos Erkko Foundation for research on developing novel imaging methods based on light and ultrasound. Light and ultrasound are utilised in many medical examinations such as monitoring blood oxygenation level and pulse, and ultrasound (echo) imaging. In addition to these conventional methods, novel imaging modalities based on light and ultrasound are being developed. Photoacoustic tomography is an emerging imaging modality in which tomographic images are formed based on photoacoustic effect. The research team of Dr Tarvainen investigates mathematical modelling and image reconstruction of photoacoustic tomography with an aim at developing the method towards a quantitative imaging modality.
