My focus research is developing an experimental setup that harnesses molecular beam spectroscopy to explore quantum electrodynamic corrections. For example, developing hydrogen molecular source, beam geometry alignment, UV ionizing laser, ion detection system, spectroscopy laser, ultra-accurate measurements of molecular rovibrational line, theoretical simulations or estimations, and experimental data analysis.

I specialize in the development of optical, electronic, and control systems for high-precision molecular spectroscopy, with applications in fundamental science and metrology. 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.

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.

I’m a theoretical physicist working in the broad field of atomic, molecular and optical physics. I study the effects of quantum scattering and spin-dependent interactions on the fine-structure resolved electronic and rotational spectra of atmospheric oxygen, and I simulate the dynamics of optical trap loading with effusive molecular hydrogen beams.

Within our research group I specialize in conducting cryogenic spectroscopy of molecular hydrogen. My work focuses on experimental physics, including the design and development of measurement systems. Additionally, I am involved in constructing and performing simulations of electrostatic systems used for detecting H2+ ions generated through the 2+1 REMPI (Resonance-Enhanced Multiphoton Ionization) process. My scientific interests revolve around fundamental physics, high-resolution laser spectroscopy, particularly saturation spectroscopy, and electronics, with a strong emphasis on instrumentation and signal processing.

I am involved in the construction of an optical system with high-power lasers, designed to precisely couple the laser beam into an ultra-high finesse cavity. My work includes assembling, aligning, and fine-tuning optical and electronic components to ensure the system’s stability and high performance. A key aspect is the ultra-stable stabilization of cavity modes, which requires precise control and the application of advanced optical techniques. My efforts contribute to high-precision optical metrology and experiments that demand the highest level of laser stabilization quality.

In my research, I focus on two main aspects. First, I investigate the influence of collisional effects on molecular spectra. For this purpose, I perform advanced quantum-scattering calculations and determine collisional line-shape parameters, which are significant for astrophysical and atmospheric applications. Second, I study the structure of simple bound and quasi-bound systems, including hyperfine couplings, to provide reference points for accurate spectroscopic experiments essential for fundamental studies.
