About Us

The laboratory is managed and operated by Julia Collins.

Bob (Robert) Ditchburn joined GNS Science in 1964 where he has developed chemical and radiochemical methods for uranium series dating of carbonates and for measuring lake sedimentation rates with 137Cs and 210Pb. He has set up uranium series procedures for alpha spectrometry at Florida State University (1984) and for thermal ionization mass spectrometry at the University of Queensland (1994). In recent years, he has refined the chemistry for 32Si dating of groundwater and sediment, and for extracting 10Be from water, sediment and ferromanganese deposits, and has produced models for dating Antarctic soils with 10Be and hydrothermal deposits using 210Pb and 226Ra.
