I graduated in Astronomy with a Bachelor’s (2017) and a Masters degree (2019) at Nicolaus Copernicus University. Both my theses focused on inhomogeneous cosmology and cosmology simulations; my Bachelor thesis focused on a more general, less constricted cosmological model and early galaxy formation within it, while my Master’s thesis dealt with a cosmological code that solved general relativity equations by going beyond the simplified equations used in most large-scale Universe simulations, and looking at additional effects during large-scale structure formation that may arise when we allow such a treatment.

My research interests revolve around gravity, which encompasses a large mass of topics such as large-scale structure formation (galaxy clusters, cosmic web), subtle, non-intuitive effects arising from more detailed approaches to general relativity (such as vector and tensor perturbations of the metric), and the field of “void science”, which treats massive empty regions of our Universe – cosmic voids – as a convenient laboratory of gravity. The last topic is the main focus of my PhD at Academia Copernicana.

I’m also currently working on a software package – a relativistic simulations code gevolution, preparing a full documentation of said code in collaboration with the developers at QMUL, London, and planning on further work in the topic of cosmology software development.
