Earth Sciences Division Staff: Christopher Hubbard
Geological Project Scientist
Chris Hubbard is currently the experimental lead on the Monitoring and Modelling component of an Energy Biosciences Institute funded research program looking at Microbially Enhanced Hydrocarbon Recovery and Biosouring. This involves designing, performing and coordinating batch and column experiments investigating diagnostic geophysical and isotopic signatures. Chris' research focuses on electrical (bio)geophysics and geochemistry. His work has spanned well-constrained lab experiments (e.g. U(VI) sorption, University of Bristol postdoc), more complex column experiments (biogeophysics, University of Leeds postdoc and current work) and field investigations (acid mine drainage, University of Reading PhD).
- Electrical (bio)geophysics: investigating (bio)geochemically induced electrical signatures (spectral induced polarization and self potential) in porous media associated with mineral precipitation and mineral-water interface processes.
- Stable isotope geochemistry: focusing on S and O isotopes during both sulfate reduction and sulfide oxidation processes.
- Contaminant transport and retardation processes.
- Microbially Enhanced Hydrocarbon Recovery and Biosouring.
- 2002-2007 University of Reading, UK
- PhD Environmental Geochemistry
“Acid mine drainage generation and transport processes in the Tinto River, SW Spain.” This study involved seasonal fieldwork and sample characterisation using a wide range of geochemical techniques (ICP, XRD, XRF and stable isotopes).

- MSc Environmental Biogeochemistry, Distinction
My MSc dissertation characterised catechol 2,3-dioxygenase genes involved in oil spill bioremediation.

Geological Project Scientist – Earth Sciences Division
I am the experimental lead on the Monitoring and Modelling component of an Energy Biosciences Institute funded research program looking at Microbially Enhanced Hydrocarbon Recovery and Biosouring. This involves designing, performing and coordinating batch and column experiments investigating diagnostic geophysical and isotopic signatures.
- Sep 2008 – Aug 2011, University of Leeds, UK
Postdoctoral Research Assistant - School of Earth and Environment
I applied laboratory-based geophysical techniques to study biogeochemically induced transformations and processes in porous media: (1) Self Potential/biogeobattery study of microbial Fe(III)-reduction in flow-through columns; (2) set-up of Spectral Induced Polarisation (SIP) instrumentation in Leeds and pilot study with polarizable minerals; (3) interpretation of electrical data from tests on tight gas sandstones at varying pressure.
- Feb 2007 - May 2008, University of Bristol, UK
Postdoctoral Research Assistant - Earth Sciences
This project developed surface complexation models of U(VI) sorption on Fe/Mn (oxyhydr)oxides by modelling the results of batch experiments, taking into account crystal structures, EXAFS and ab initio quantum mechanical modelling of molecular geometries. My duties involved batch experiments, running the ICP-MS and data modelling.
- Oct 2007 - Jan 2008, University of Reading, UK
Part-time Sessional Lecturer
I delivered a first year module on Earth Structure and Materials consisting of 10 lectures and practical classes, as well as marking essays and practical notebooks.
- Apr 2001 – Oct 2001, Parkman Ltd. (now Mouchel Ltd.), UK
Graduate Environmental Scientist
Duties included desk studies, supervision of contaminated land site investigations, undertaking monitoring and sampling programmes and managing the office Environmental Management System.
Collaborations and Professional Memberships
I enjoy collaborative work with external organisations and experts. To date I have collaborated/visited with Rutgers-Newark University, NJ (SIP instrumentation); University of Manchester, UK (geomicrobiology); University of Huelva, Spain (acid mine drainage field monitoring), the Jet Propulsion Laboratory, CA (acid mine drainage isotopes), University of California Berkeley, CA (microbiology and isotopes) and Penn State (reactive transport modelling). I am a fellow of the Geological Society of London and a member of the American Geophysical Union and the Geochemical Society.
