My main research interest is scientific computing with applications to quantum structure. I am developing computer programs and efficient methods for solving the non-relativistic and relativistic wave equations for atomic systems. From the wave functions different properties such as energy structure, hyperfine structure, isotope shifts, transition rates, and splittings due to external magnetic fields can be determined. Atomic data are needed to understand and model astrophysical and fusion plasmas. Combined with high precision experimental energy structures, computed atomic data can be used to infer properties of the atomic nucleus. The work is done in close collaboration with several leading research groups in USA, Europe, China, and Japan. The research on quantum structure is financed by the Swedish Research Council. We also have a Baltic Sea network with short term visits supported by the Swedish Institute Visby program. I am a member of the Computational Atomic Structure Group (COMPAS), an international group for atomic physics. I am a founding member of the Lund-Malmö Center for Atomic Systems - Researching processes in Plasma and Astrophysics (LUMCAS) which gathers researchers in theoretical and experimental atomic physics as well as in astrophysics.
More recently I have been concerned with the use of data from satellites for collecting information about the land surface, primarily vegetation. Together with the research group in Ecosystem Analysis at Lund University (Prof. Lars Eklundh) I have primarily been working with data from the AVHRR of the NOAA satellites and from the Sentinel satellites in order to analyze their usefulness for global and regional environmental monitoring and mapping in different climatic regions. The need for efficient data analysis has led to the development of novel methods for processing of time series of satellite sensor data. The methods have been implemented in the program package TIMESAT, which has a user community of more than 5000 researchers. The methods are useful for investigating vegetation seasonality and for studies of long-term and short-term vegetation changes. Currently I participate in a project to study the effects of variations in phenology on Swedish forests and forest management in a future climate change perspective.
I am also engaged in education and technology and have acted as the leader for the project Mathematics for the Digital Generation supported by the Wallenberg Foundation. I have been a board member of the national research school on science and mathematics didactics (FontD).
I teach at various mathematics and programming courses at the Center for Technology Studies. I also act as supervisor for MSc and
PhD students. During several years I have been engaged in developing course material and I have written four books on computing and applied mathematics. Supported by the EU-exchanged programs I have been teaching and lecturing abroad at a number of occasions.
