The beautiful thing about a statistical analysis is that,
when done right, it includes the odds of being incorrect.

About me


I am an associate professor at the Institute of Astronomy of the Nicolaus Copernicus University in Toruń, Poland.

My research focus is on the high-energy astrophysical phenomena, like gamma-ray bursts or blazars. In particular, I employ a range of time series analysis techniques to investigate their variability properties in order to connect them to physical characteristics.

In addition to this primary line of research, I am also interested in: My earliest research (PhD topic) was on the chaotic rotational dynamics of Hyperion, a highly aspherical moon of Saturn.
