Robert Mistrik (46), HighChem, Slovakia, has 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. He is the author of precursor ion fingerprinting method that allows identification of metabolites based on substructural identities of tandem mass spectra. In 2009, he was awarded the Head of the Year prize, a national award for exceptional achievements in science and technology. Dr. Mistrik has been a member of the scientific steering committee of the METAcancer consortium, aiming to identify small molecule biomarkers in breast cancer tissue. Currently, he is leading the m/z Cloud initiative that is a collaborative effort to build a comprehensive spectral trees library for identification of metabolic components utilizing molecular evolutionary patterns.
