Ryan Tappero

Lead Scientist, XFM Beamline

Ryan Tappero earned a B.S. in Soil Science and a M.S. in Soil Chemistry at Cal Poly, San Luis Obispo, and a Ph.D. in Environmental Soil Chemistry at the University of Delaware in the laboratory of Dr. Donald L. Sparks. His research focuses on the transformation, speciation and bioavailability of trace elements in soil and the rhizosphere, and the mechanisms of uptake, metabolism and tolerance in higher plants. After conducting postdoctoral research at the National Synchrotron Light Source (NSLS) under the direction of Dr. Lisa Miller, he assumed the position of Spokesperson and Lead Scientist at Beamline X27A. Ryan works to develop new synchrotron-based X-ray imaging methods and to apply these to problems in biogeochemistry. At the National Synchrotron Light Source-II (NSLS-II), he serves as the Lead Scientist for the XFM beamline, a versatile X-ray Fluorescence Microscope, and a development team member for the Tender Energy Spectroscopy (TES) beamline. Ryan also holds an adjunct faculty appointment in the Department of Plant and Soil Sciences at the University of Delaware.
