astrophysics; radio astronomy; active galaxies; relativistic jets
I started as a researcher in the Turku Collegium of Science and Medicine in September 2016. I obtained my PhD in 2009 from Helsinki University of Technology (now Aalto University) on the topic Radio variability of active galactic nuclei: analysis of long-term multifrequency data. I then worked as a postdoctoral research at Purdue University USA (2009-2011) and California Institute of Technology USA (2011-2014). I moved back to Finland in 2014 to work as Academy of Finland postdoctoral fellow at Aalto University, from where I moved to Tuorla Observatory when starting in the collegium researcher position. Since September 2018 I have been working as an Academy of Finland Research Fellow at the Finnish Centre for Astronomy with ESO.
My main research interest is in active galaxies and their relativistic plasma jets. In my research, I use observations at all wavelengths from radio to very-high-energy gamma rays. At the moment I'm especially interested in magnetic fields in the plasma jets, and how they affect the jet formation and radiation. I use polarization observations in the radio and optical wavelengths to study the magnetic field structures in the jets. For example, I have studied the magnetic fields around jets using millimeter-wavelength observations from the ALMA observatory. I'm also involved in several international research projects where the jets of active galaxies are studied in multiple wavelengths. Recently, I expanded my research to multimessenger astrophysics by studying the connection between the radio emission of active galaxies and the arrival times of high-energy neutrinos.
I teach in two Master level courses "Radio Astronomy" and "Active Galactic Nuclei". I also advice B.Sc., M.Sc., and Post graduate students.
