Andrew Bruhacs Andrew Bruhacs is a trained chemist who graduated with a diploma degree from the Johannes-Gutenberg University in Mainz, Germany in 2008. During this period, under the supervision of Prof. WolfgangTremel he published works regarding the synthesis, characterization and tribological applications of transition metal chalcogenide inorganic fullerenes, in collaboration with the LTDS institute in Lyon.
His knowledge in organic and computational quantum chemistry later led to collaborations with the Carr-Parrinello MD simulation group of Prof. Radu Iftimie at the Université de Montreal, Canada where he set the stage for modeling excited state proton transfer (ESPT) processes in aqueous media. To deepen the understanding of ESPT further, during the start of his PhD at McGill University he built and conducted femtosecond broadband pump-probe spectroscopy experiments covering the UV/Vis and mid-IR in the ultrafast structural dynamics lab of Prof.n Bradley Siwick. In collaboration with the team of Prof. Mohamed Chaker at INRS-EMT he discovered and characterized a metastable ultrafast photo-induced phase of vanadium dioxide (thin film) using mid-IR spectroscopy as well as sub-picosecond ultrabright electron pulses.
Following his graduation from McGill University in 2015 he is currently working as a post-doctoral researcher (since April 2016) in the nonlinear photonics group of Morandotti, focusing on technologies for THz generation, detection as well as THz thermal imaging applications in biological tissue. In 2017 he was granted a 2-year FQRNT fellowship to pursue work on adiabatic three-wave mixing in temperature-controlled bulk crystals as well as the theoretical study nitrogen ion lasing phenomena in laser-induced plasma sparks.
