I received my PhD degree from Imperial College, Univ. of London in 2002. After this I held postdoctoral positions at Stockholm University, Helsinki University of Technology (now Aalto University) and Queen's University Belfast. I moved back to Finland in 2007 with an Academy of Finland Research Fellowship to work at Tuorla Observatory at University of Turku. Between 2012 and 2015 I worked at the Finnish Centre for Astronomy with ESO (FINCA) as a University Researcher. I was appointed as a Professor of Astronomy at the Department of Physics and Astronomy at University of Turku in 2015. After 2010 I have made extended research visits to Stockholm University (18 months) and to University of Cambridge, UK (10 months). I have been the Finnish delegate in the European Southern Observatory (ESO) Council since 2020 and in the International Scientific Committee (CCI) of the Roque de los Muchachos and Teide observatories since 2019. Since 2022 I have also served as the President of the CCI. I am currently also the President of the Finnish National Committee for Astronomy and a member of the Nordic Optical Telescope (NOT) Council and the board of FINCA, and a vice member of the board of the Univ. of Turku Faculty of Science. In 2022 I was invited as a member of the Finnish Academy of Science and Letters.




​​​​​​My main research interests focus on observational work on extragalactic astrophysical transients, including supernovae, tidal disruption events, and kilonovae. For more details on my research and information on the research group please see https://sites.utu.fi/sne/. For a complete list of my refereed journal papers see ADS (in chronological order) or ADS (ordered by number of citations).

I have taught several courses in astronomy, astrophysics and signal and image processing at the Univ. of Turku. In  particular, I initiated two new observational astronomy courses currently offered at national level for students from Turku, Helsinki, Oulu and the Aalto University. These courses offer hands-on experience on the use of the Nordic Optical Telescope (NOT) remotely from Univ. of Turku (Observational Techniques Using the Nordic Optical Telescope) and on the science exploitation of data from the European Southern Observatory (ESO; Data Processing Techniques for Astronomy with ESO Instrumentation). Currently I teach also the BSc course on observational astronomy and the MSc courses Spectroscopic Diagnostics in Astrophysics and Signal and Image Processing. In my teaching I always try to make use of examples from the latest research in order to offer a motivating learning experience for the students.
