After all, science is essentially international, and it is only through lack of the historical sense that national qualities have been attributed to it.
Marie Skłodowska-Curie

Science makes people reach selflessly for truth and objectivity; it teaches people to accept reality, with wonder and admiration, not to mention the deep awe and joy that the natural order of things brings to the true scientist.
Lise Meitner



Studying the proton spin structure with STAR

How the spin of a nucleon arises from the spins and orbital angular momenta of quarks and gluons? This fundamental question in hadron physics remains not completely answered. Experiments with polarized proton-proton collisions can bring us closer to the comprehensive understanding of the internal spin structure of matter.

Polarimetry for storage ring EDM experiments

The origin of the matter-antimatter imbalance in the universe is one of the grand puzzles of modern physics. Searches for Electric Dipole Moments of charged hadrons within the JEDI collaboration can shed the light on the new sources on the CP-symmetry violation which could explain the observed preponderance of matter in our world.

Diffractive interaction of protons at CDF

Central exclusive production processes are characterized by large regions in forward rapidity devoid of hadrons, and a centrally produced state, in our case pairs of charged mesons. This class of reactions measured at TeV energies has an important role in meson spectroscopy, favoring states having valence gluons, such as glueballs.

Probing proton mass with WASA

The fact that up and down quarks have slightly different masses has quite some impact on our existence, resulting in proton being heavier then neutron, and therefore stable. Net effects of quark-mass differences can be studied in hadronic reactions, e.g., in the reaction measured with the WASA-at-COSY experiment.

To push further the frontier of our knowledge, we, as a community of scientists, cannot forget how essential popularization of science is. We can build state-of-the-art experimental facilities and create revolutionary theories and ideas, but as long as we do not have a diverse generation of enthusiastic young people with a critical-thinking attitude to continue our work, we cannot expect to achieve any long-lasting progress.

STEM outreach and education is an essential part of my mission as a scientist. See below some examples of my activity.


Teaching and Content Development

Promoting STEM and sharing the joy of science with students and general audience is one of my passions.

Early-career scientist associations

Throughout my career, I’ve been heavily involved in initiatives supporting early-career scientists.
