PhD Position on Isotopomer Studies of Plant-climate Interactions, Department of Medical Biochemistry and Biophysics, Umea University, Sweden Little is known on interactions between plants and atmospheric and climate change on time scales of centuries. The goal of the project is to deduce separate climate and physiological signals from tree rings, to be able to detect these interactions. We have developed an approach to measure isotopomer abundances (i.e. the intramolecular distributions of stable isotopes in metabolites), by NMR spectroscopy. Isotopomers turn isotope abundances into multiple information channels, as basis for parallel reconstruction of climate and physiological signals. The PhD project will focus on the deuterium isotope, applied to tree ring series and material from annual plants. The research environment includes chemists, earth scientists, and forest ecology. Qualifications: Applicants must have a master’s degree in chemistry, earth sciences or a related field. We s...
