My research focuses on two key areas. First, I study the structure and interactions of simple molecules, including hyperfine couplings and interactions with external fields, in the context of accurate spectroscopy for fundamental studies. Second, I investigate the interplay between collisions and spectroscopy through rigorous quantum scattering calculations to deepen our understanding of collisional effects in molecular spectra. To this end, I develop efficient computational tools that produce accurate reference data, including rate coefficients and collisional line-shape parameters, for astrophysical and atmospheric applications.

Nikodem Stolarczyk, PhD
I specialize in the theoretical foundations of molecular optical resonances, developing models and calculating line profiles from first principles. My work combines numerical methods, data analysis, and theoretical approaches to enhance laboratory data modeling and interpretation. What excites me most is integrating experimental and theoretical results to derive meaningful physical conclusions. Beyond theoretical research, I have extensive experience in developing optical setups, preparing and performing laboratory measurements. I also enhance the accessibility of our scientific output by integrating our group’s calculated and measured data into major spectroscopic databases. I contribute to the development of database structures and develop refinements to improve their organization and usability.
Michał Żółtowski, PhD
I specialize in quantum scattering studies, focusing on two key areas: astrochemistry and molecular spectroscopy. In astrochemistry, I calculate collisional rate coefficients to aid in the interpretation of astrophysical observations. In molecular spectroscopy, I use ab initio quantum scattering methods to determine spectroscopic parameters essential for accurate molecular spectrum modeling. The complexity of these calculations requires substantial computational resources, including memory and CPU time on supercomputers, which require optimization strategies to ensure feasibility and efficiency. My goal is to provide highly precise collisional data to advance these fields.

My work lies at the intersection of physics, mathematics, and engineering: a triple point I’m unwilling to exit. With a background in applied mathematics, control theory in particular, I integrate advanced control techniques and develop tools to advance precision spectroscopy.
Kamil Stankiewicz, MSc
I specialize in the design, development, and application of laser, optical, and electro-optical systems for ultra-precise molecular spectroscopy, with a particular focus on cavity-enhanced techniques. Currently, the systems I work on are used, among other applications, for ultra-precise spectroscopy of cryogenic hydrogen molecules for fundamental physics research, the realization of SI standards, molecular collision studies, trapping of weakly interacting neutral molecules, and the detection of sparse molecular distributions via REMPI ionization. The laser sources I utilize span from the mid-infrared (MIR) to the ultraviolet (UV), covering continuous-wave (CW) to femtosecond regimes. They include diode lasers, dye lasers, optical frequency combs, optical parametric oscillators, and frequency-mixing systems.
