Robert Mistrik, HighChem, earned a masters degree in chemistry from the Slovak Technical University, Bratislava, Slovakia and a Ph.D. from the University of Vienna, Austria. He held a postdoctoral position at the National Institute of Standards and Technology (NIST), Gaithersburg, MD, USA. He is the creator of Mass Frontier, a software for processing and interpreting mass spectral data in which the spectral tree concept was introduced. In 2009, he was awarded the Head of the Year prize, a national award for exceptional achievements in science and technology. Currently, he is leading the m/z Cloud initiative that is a collaborative effort with Thermo Fisher Scientific to build a comprehensive spectral trees library for identification, confirmation, and quantification of thousands of compounds. The High-Resolution Accurate-Mass MS/MS Spectral Libraries for use with Thermo Scientific™ Q Exactive™ Quadrupole-Orbitrap Mass Spectrometer systems can be continually updated from the ever expanding mzCloud™ online repository and customized with lab-specific compounds and spectra.
