We mourn the loss of Sam Boldissar (1992-2017) who passed away in a rock climbing accident this March at Joshua Tree National Park. Sam (center left in the photo above, beside Mattanjah) was first and foremost our friend who had a brilliant mind and passion for science, the California outdoors, and his family and friends. Sam was ever humble and his enjoyment of life was infectious. We are better for knowing him and absolutely devastated he is no longer here. -March 2017
Sam had his hands in everything within our lab and we are currently preparing his works for publication. Please look firstly to his work on the photorelaxation dynamics of 6-thioguanine (published June 2017 Phys. Chem. A) .

In the de Vries group, we use state-of-the-art spectroscopy to explore dynamics and properties of compounds in the gas phase that have previously been unexplored. By coupling Resonant Enhanced Multi Photon Ionization (REMPI) with TOF-mass spectrometry, we are able to wavelength and mass select to distinguish isomers in the instrument. Through this, properties such as the vibrational modes and excited state lifetimes of molecules in the gas phase. This results in an analysis of compounds free of solvent interactions. Currently, we have split our research efforts into two major fields: the analysis of canonical and alternative nucleobases and the study of art and pigments to better understand the photo-stability of these compounds.
