Research Associate Chemical weathering and hydrology in a Nepalese catchment - a non-traditional stable isotope geochemistry approach (Fixed Term)

We are seeking a postdoctoral researcher to work on a joint NSF-NERC grant (Cambridge, USC, U Michigan, UC Berkeley), investigating the couplings between erosion, weathering and hydrology in an active orogenic system by making a detailed study of the Melamchi catchment in Nepal. The project will investigate the impact of exhumation rate on rock properties and landsliding and how these interact with physical and chemical weathering. The project will map rock properties by sampling, shallow seismic profiling, electrical resistivity tomography and shallow drilling. The hydrological structure will be investigated by sampling groundwaters and rivers, measuring water chemical and isotopic compositions and using short-lived tracers to measure water residence times.

The Cambridge contribution will be to use traditional and non-traditional radiogenic and stable isotope analyses in conjunction with water geochemistry combined with reactive-transport modelling to constrain the hydrological structure and fluid-mineral interactions in the weathered rock mass. The postdoctoral researcher will be expected to take part in the field work in Nepal, analyses of the geochemistry and radiogenic and/or stable isotope compositions of waters and minerals (some of Mg, Ca, Si, Sr, Li, S & δ18OSO4 ) and be involved in the reactive-transport modelling.

The successful applicant will have experience in the analysis of radiogenic and/or non-traditional stable isotope ratios using either TIMS or MC-ICP-MS and an interest in reactive-transport modelling. She/he will either hold a PhD (or equivalent) in geosciences or a related discipline or have recently submitted a PhD dissertation in these areas. The successful candidate will have the ability to work in a team and have previous field experience. She/he will preferably have a track record of publication in peer-reviewed international journals and have good communication skills in order to present results at international meetings.

Fixed-term: The funds for this post are available for 2 years in the first instance.
