Dr. Burr has been working in
the NSF-Arizona AMS facility since 1990. He received his PhD from the University of Chicago. He was a Fulbright
2006-2007 scholar. Dr. Burr is also a Chair Professor
of Geosciences at National
His research is aimed at improving
pretreatment techniques and new AMS systems. He has published on methods for
pretreating coral samples using selective dissolution, described a
technique for measuring radiocarbon in groundwater dissolved organic
carbon (DOC), and experimented with stepwise combustion of sediment, iron
artifacts and pottery samples at different temperatures.
He has also written on the
radiocarbon calibration, using corals which lived at a time when no
tree-ring data was available. He h as supported a large number of studies
of paleoclimate and paleoenvironment and has participated in extensive
field work, bridging the gap between the field and the laboratory.
