I am a postdoctoral fellow at the Center for Theoretical Physics, Polish Academy of Sciences, Warsaw, Poland, working with Prof. Bozena Czerny. My research interest covers all aspects of AGN from highly relativistic jets pointing towards the observer (blazars) to non-jetted AGN such as quasars and Seyfert galaxies.
