Current position
Research Officer
Research interests
Primary duties are the maintenance and improvement of mass spectrometry,
with independent research and support for other researchers. We
have recently installed our 4th operational mass spectrometer,
destined for the analysis of hydrogen isotopes in environmental
systems, with a main focus on Calvin Cycle metabolites and plant
water. The machine installation was accompanied by a switch to
a new high-temperature furnace system which has necessitated the
development of new reaction columns etc.
As I come from an archaeological and geological background, I
find it difficult to tear myself away from things that have a
palaeoenvironmental slant. I have previously worked on speleothems
and oxygen isotopes in bone phosphate. My research here will therefore
tend toward aspects of plant isotopes that reflect on palaeoenvironment,
and I want to continue working on phosphates in plant and animal
systems. I also enjoy tinkering, programming and equipment development,
so given the excellent development facilities here I hope to experiment
with various weird ideas for isotope analysis.
