Dr. Marginean obtained his Ph.D. from the group led by Dr. Akos Vertes in the Department of Chemistry at George Washington University, where he focused on fundamental understanding of the two most successful ionization methods for mass spectrometry (matrix assisted laser desorption/ionization and electrospray ionization). His thesis describes a consistent classification of axial electrospray operating regimes based on non-linear liquid dynamics. His research improved the description of the burst and pulsating regimes and unraveled the astable regime, which is an alternative chaotic route between the pulsating and the cone-jet regimes. He tackled the controversial ion formation mechanism during electrospray ionization using molecular dynamics simulations. He also contributed to research revealing the energy transfer during laser-solid interactions.
After post-doctoral training in the Biological Separations and Mass Spectrometry Division at the Pacific Northwest National Laboratory (PNNL), Dr. Marginean was hired as Senior Research Scientist in the group led by Dr. Richard Smith. The research in the group uses high resolution separations coupled to mass spectrometry (HPLC-MS) to answer relevant biological questions. His focus shifted to analytical applications of low-flow and sub-ambient pressure electrosprays and worked on development and characterization of new technologies (electrospray-based ion sources).
Dr. Marginean joined the Department of Forensic Sciences as Assistant Professor in October 2013. He is interested in applications of mass spectrometry in forensic sciences.
