Ryan Tappero Microprobe Scientist Ryan serves as the beamline scientist and spokesperson for Beamline X27A, a hard X-ray microprobe, and works in the Life and Environmental Sciences Group under the supervision of Lisa Miller. Ryan obtained his B.Sc. in Soil Science in 2001 and his M.Sc. in Soil Chemistry in 2003, both from California Polytechnic, San Luis Obispo (Cal Poly). During his graduate study at Cal Poly, Ryan worked as an intern geochemist for the CA Regional Water Quality Control Board. Ryan obtained his Ph.D. in Environmental Chemistry from the University of Delaware in 2008. His Ph.D. research involved using X-ray and electron microscopies to study the molecular speciation of heavy metals in hyperaccumulator plants used for remediation of contaminated soil and sediment. At the NSLS, Ryan provides scientific and technical support for X27A users and works on the development of environmental sciences applications at the facility. In his spare time, Ryan enjoys hiking, fishing, backpacking, snowboarding, boating, sunrise or sunset on the beach, playing guitar, and walking the dogs. Professional Activities
