Dr.Vladimir Paskalutsa

I am a Senior Staff Scientist at the Institute for Nuclear Physics of Johannes Gutenberg University Mainz, Germany. My work has developed around questions that sit between theoretical nuclear and particle physics, hadronic physics, and precision atomic physics. I am particularly interested in situations where a small discrepancy, a subtle symmetry, or an unexpectedly precise measurement can reveal something deeper about the structure of the Standard Model.

My research combines phenomenology with more formal aspects of quantum field theory. Over the years, I have worked on effective field theories, chiral dynamics with resonances, relativistic higher-spin fields, dispersion relations, sum rules, hadronic structure, and the connections between phenomenological methods and lattice QCD. Much of this work has been driven by precision problems: hadronic vacuum polarization and light-by-light scattering in lepton (g-2), two-photon exchange, nucleon and nuclear structure, and spectroscopy of simple and muonic atoms.

Books and long-form scientific writing have become an important part of how I think about physics. A book forces one to ask different questions from a research paper: what is essential, which ideas truly belong together, and what can be understood only after stepping back from the technical details. I enjoy trying to uncover these underlying structures and to present difficult subjects in a way that preserves both their precision and their sense of discovery. For me, writing is not separate from research; it is another way of finding out what one really understands.

Teaching has a similar role. I teach advanced courses in nuclear, particle, and precision physics, often using current research problems as a point of departure. I prefer to show students how ideas emerge, where approximations enter, and why certain questions remain open, rather than presenting physics as a finished collection of results. Mentoring young researchers is a natural extension of this approach. I value independence of thought, curiosity, and the willingness to follow an unexpected line of reasoning when the physics seems to demand it.

I have also been involved in organizing conferences, workshops, and focused scientific meetings. I am especially drawn to meetings that bring together communities that do not always speak the same technical language—nuclear, particle, atomic, and hadronic physics, theory and experiment. Some of the most interesting developments tend to appear at these boundaries, where a familiar problem is seen from a different angle.

My professional activities also include editorial work, peer review, evaluation of research projects, and participation in international collaborations and scientific programs. I see these roles less as administrative duties than as part of the intellectual life of the field: a way of recognizing promising ideas, maintaining standards, and helping create the conditions in which new work can emerge.

A recurring theme in my research is the attempt to derive as much as possible from general principles—symmetry, analyticity, unitarity, effective field theory, and sum rules—before introducing detailed models. I am often most interested in relations that seem almost too simple at first sight, but turn out to connect observables or physical regimes that were thought to be unrelated. That search for hidden structure continues to shape the way I approach research, teaching, and scientific writing.
