Research interests

I am interested in discovering fundamental mechanisms of chemical reactions in the gas phase. How and why do molecules react? What are the ways of steering the outcome of their reactions? Can we rationally design new fuels or improve the biomass conversion processes? These questions can be answered by a combination of the experiments that I am conducting using the chirped-pulse millimeter-wave (CPmmW) spectroscopy and the theoretical support I am receiving from my colleagues. In particular, we are investigating the contributions from the roaming radicals dynamics, non-thermal effects, quantum tunneling, and H-atom addition/elimination to the outcomes of chemical reactions in different experimental environments.

Pyrolysis reactions

In this research effort, complex networks of chemical reactions are thermally initiated in the micro-tubular pyrolysis reactor (Chen nozzle) heated to 8001900 K. The reaction products are cooled in the supersonic expansion to ~10 K where they are observed and quantified using CPmmW spectroscopy. Based on these measurements, and with the help of kinetic modeling, reaction networks are built and new chemical pathways are discovered.

Time-Resolved Kinetic Chirped-Pulse spectroscopy

In this novel experimental approach, chemistry in my room temperature flow-tube reactor is initiated by UV laser pulses. Subsequent reactions and thermalization of energized photo-products are observed with a time- and vibrational quantum state-resolved chirped-pulse rotational spectroscopy. Vibrational population distributions of reaction products are a key to discovering new reaction mechanisms.

Assignment of rotational spectra using artificial neural networks

Increasing throughput of spectroscopic data from broadband chirped-pulse rotational experiments opens new opportunities for chemical research. At the same time, assignment of broadband rotational spectra and identification of chemical species becomes a bottleneck. We have demonstrated the potential of machine learning for sorting through these spectroscopic data and eventually converting them to chemical information.
