I am the PI of a project financed by the National Science Center, Poland, whose main goal is to study magnetically active stars and measure their activity cycles.

Research Assistant in the project financed by the National Science Center, Poland.As a part of this project, I prepared a doctoral thesis entitled: "Mapping the Structure of the Milky Way with Mira Stars". I published the results in four papers in the peer-reviewed international journals. I was also involved in teaching students on courses devoted to statistics and basics of programming and data analysis.As a member of the Optical Gravitational Lensing Experiment (OGLE) project, I actively observe the sky using the Warsaw Telescope located in Chile. I have spent over 200 observation nights on this telescope, as well as on others located in Greece, Italy or Slovakia.

I was responsible for analyzing the scientific data from the ground-based telescopes and looking for degeneracies in the gravitational micro lensing phenomenon.
