Hi, my name is Krzysztof (Kris) Rybicki. I did my PhD in Astronomical Observatory, University of Warsaw and defended it in 2022. Currently I am a postdoctoral fellow at the Weizman Institute of Science in Israel. Anything on the redshift > 0 is difficult to grasp for me and so I am mostly working on the stuff that is happening in our Galaxy, its structure and stellar populations. I am particularly interested in the fate of stellar remnants like neutron stars or black holes. I also somewhat care about extrasolar planets - a topic slightly less mysterious, but maybe even more intriguing. The thing that is common for these objects is that they are usually very faint (or emit no light at all), which is why the perfect way to study them is through the gravitational microlenisng, of which I am a big fan.
