Peter Nemes

Peter Nemes, Ph.D., is a Hungarian-American chemist, who is active in the fields of bioanalytical chemistry, mass spectrometry, cell/developmental biology, neuroscience, and biochemistry. Dr. Nemes has been an associate professor at the University of Maryland, College Park (UMD) since January 2018. Prior to his appointment there, he was an assistant professor at the Department of Chemistry at George Washington University (Washington, DC), where he taught bioanalytical chemistry.[1]

Peter Nemes graduated with summa cum laude with a Master's of Science (M.Sc.) from the Eötvös Loránd University in 2004. His original thesis research was conducted in the Department of Mass Spectrometry at the Hungarian Academy of Sciences, Budapest, Hungary. Under mentorship by Dr. Vekey Karoly, Mr. Nemes studied the formation of amino acid clusters in the gas phase upon electrospray ionization,1 such as the magic serine clusters that preferentially incorporate amino acids and sugars of certain chirality matching those enriched on Earth. During his PhD in Prof. Dr. Akos Vertes’ laboratory at the Department of Chemistry, The George Washington University (GWU; Washington, DC) between 2005–2009, he established the significance of spraying modes/regimes during electrospray ionization (ESI) mass spectrometry (MS) in efficient and soft ion generation2 and the confirmational state of proteins3. He also invented and patented laser ablation electrospray ionization (LAESI)4 mass spectrometry for in situ and in vivo analysis4 of tissues and single cells5 2- and 3-dimensional molecular imaging MS6 at ambient conditions for biological samples. He completed postdoctoral training in analytical neuroscience with Prof. Dr. Jonathan V. Sweedler at the University of Illinois at Urbana-Champaign, IL. There, he developed capillary electrophoresis ESI MS instruments7 and built a unique matrix-assisted laser desorption ionization (MALDI–C60 secondary ionization mass spectrometry (SIMS) dual-ion source mass spectrometer8 to enable the analysis of small and large molecules in single cells.9

In 2011, Dr. Nemes became a Staff Fellow and then also Laboratory Leader at the US Food and Drug Administration (2011–2013). An independent investigator, Dr. Nemes developed a high-throughput approach10 based on Direct analysis in real time to enable the rapid differentiation of heparin from glycosaminoglycans, including authentic adulterated products confiscated by the FDA during the 2008 heparin crisis. Dr. Nemes also established the mass spectrometry facility at the White Oak Headquarters of the US FDA with several mass spectrometers to support regulatory science.

As a professor since 2013, Dr. Nemes has conducted cutting-edge research at the interface of bioanalytical instrumental chemistry and neurodevelopmental biology and taught courses in analytical chemistry and mass spectrometry. In Fall 2013, Dr. Nemes became an assistant professor at the Department of Chemistry at George Washington University (Washington, DC), where he taught analytical chemistry.[1] In January 2018, Dr. Nemes became an associate professor at the Department of Chemistry & Biochemistry, the University of Maryland, College Park (UMD), where he has been teaching instrumental analytical chemistry and biological mass spectrometry. Research in the Nemes Laboratory develops ultrasensitive and microanalytical platforms for high-resolution MS to study metabolic and proteomic processes with implications in cell and neurodevelopmental biology and health research. Using custom-built single-cell MS instruments, his research group has uncovered previously unknown metabolomic11 and proteomic12 differences between single embryonic cells that are fated to give rise to different types of tissues during vertebrate development. Their highly sensitive bottom-up proteomic approach enabled the detection intra-cell type cell heterogeneity in the embryo.13 Further, the group has also discovered molecules that are able to alter normal cell fate decisions in the embryo.11 The investigators next developed microprobe technologies that enabled the direct, in vivo analysis of these small14 and large15 molecules in cells in X. laevis embryos undergoing normal development. These results challenge basic understanding of molecular processes that are necessary for normal embryonic body and brain development and raise important implications to help understand, promote, and protect the health of humans and animals.16

Prof. Nemes has authored 46 peer-reviewed publications, 6 book chapters, and ~200 presentations. In 2015, Prof. Nemes was named a Beckman Young Investigator by the Arnold and Mabel Beckman Foundation and received the Arthur F. Findeis Award for Achievements by a Young Analytical Chemist by the Division of Analytical Chemistry of the American Chemical Society. In 2017, he received the DuPont Young Professor Award, the Robert J. Cotter New Investigator Award by the US Human Proteome Organization, and a Research Award from the American Society for Mass Spectrometry (ASMS). In 2018, Prof. Nemes was awarded the Georges Guiochon Faculty Fellowship from HPLC, Inct. Research in the Nemes Lab has been continuously funded by professional societies, companies, and federal funding agencies. Prof. Nemes holds a CAREER award from the Directorate of Biological Research of the National Science Foundation (NSF) and an Outstanding Research Award (R35) from the National Institute of General Medical Sciences (NIGMS).
