The Richardson Biogeochemistry lab investigates how biology influences the surrounding environment, and vice versa, from terrestrial to marine ecosystems. We investigate how molecular scale processes impact, and potentially control, larger scale nutrient cycles. To understand these complex and dynamically evolving processes, we primarily use advanced analytical tools, such as x-ray fluorescence microscopy, x-ray absorption spectroscopy, synchrotron infrared and mass spectrometry imaging. This combination of tools, as well as being well-situated at SLAC National Accelerator Laboratory, has led to a broad array of research ongoing in our lab including:
- The Sulfur Cycle
- Plant and Microbe Nutrient Availability
- Multimodal Imaging
- Biomineralization
- Phosphorus and Early Earth Geobiology

Our research themes in biogeochemistry are broad and varied, therefore we are always interested in new research projects where advanced analytical tools (and in particular x-rays) may be able to answer exciting science questions. If you are interested in joining the lab, or collaborating with us on an existing or new research project please get in touch!

The Richardson lab is currently seeking applications for a postdoc to work on developing a 3D printed simulated soil platform for dynamic nutrient imaging of the rhizosphere. If you are interested, reach out via email.
