We are a question-motivated lab that aims to connect modern microbe-mineral interactions with Precambrian biogeochemical cycles to understand the evolution of metabolisms and environments over time.
We use microscale and nanoscale techniques to extract primary information from Precambrian rocks and study modern biogeochemical processes to fully understand what these original minerals signal. We combine this with laboratory experiments to understand processes on a mechanistic level with modern field analogues to probe similar natural and complex environments, and tackle these integrated approaches using a variety of spectroscopic and microscale imaging tools. Check out our facilities below.
The Microbe-Mineral lab is a general purpose wet chemical laboratory with equipment for culturing and solution chemistry analyses, including an analytical balance, UV-vis spec, large and mini centrifuges, fridges, freezer, ovens, shaking incubators, pH meters, and a MilliQ water purifier. We also have a -80 freezer, a small autoclave and access to a large departmental autoclave, and a Raman microprobe and double glove box as shown below:
Double Glovebox System
Our lab has two controlled-atmosphere spaces to recreate Precambrian-like environments
Our Raman microscope can image, characterize, and co-register minerals and DNA at a micron-scale
We travel to synchrotron facilities worldwide to analyze the chemical speciation and structure of elements such as Mn and Fe.
