Laura Meredith (PI)


laurameredith[at]email.arizona.edu

I am an interdisciplinary scientist working on research questions at the intersection of environmental microbiology and atmospheric chemistry.  I am an Assistant Professor of Ecosystem Genomics in the School of Natural Resources and the Environment (SNRE) and the BIO5 Institute. Previously, I was an Associate Research Scientist with Scott Saleska (University of Arizona) and an Atmospheric and Geospace Sciences NSF Postdoctoral Fellow in Paula Welander’s geobiology lab (Stanford University) and Joe Berry‘s trace gas lab (Carnegie Institution for Science). I earned my PhD in Climate Physics and Chemistry from the Massachusetts Institute of Technology (MIT) with Ron Prinn and my BS in Chemistry from the California Polytechnic State University (Cal Poly), San Luis Obispo.

Kevin comes to the Meredith and Saleska Lab groups from Indiana University with deep knowledge (literally, gained through his PhD work in caves) in microbial methane cycling and methane isotope biogeochemistry. He is working as a key member in our US-Brazil collaboration characterize interactions between microbial biodiversity, methane cycling, and land use change in the Brazilian Amazon tropical rain forest.

Juliana Young (UA Undergraduate)


Juliana is working with the Meredith Lab and Dr. Aditi Sengupta to determine the microbial drivers of N2O emissions in the Biosphere 2 tropical rainforest. Read about her research project here.

Joseph Guerrero (UA Undergraduate)

Gabriel Kellogg (UA Undergraduate)

Sara Te (KEYS high school intern)

Joseph, Gabriel, and Sara work as a team on a project to characterize the transport of microbes in the Biosphere 2 Landscape Evolution Observatory model system.

John Meraz (REU Student)

John is working with Till Volkmann, Joost van Haren, and the Meredith Lab to develop new methods for trace gas analysis in the Biosphere 2 tropical rainforest.

Collaborative Relationships

The Meredith Lab embraces collaboration as a cornerstone for interdisciplinary research, including the following efforts

Microbial methane cycling in the Brazilian Amazon – a budding collaborative effort in methane isotope microbiogeochemistry in the state of Pará (http://www.saleskalab.org/research/amazon-research/)

Biosphere 2’s Landscape Evolution Observatory (LEO) – microbial and trace gas dynamics in an evolving hillslope (http://biosphere2.org/research/projects/landscape-evolution-observatory)

Ecosystem Genomics Initiative – A new initiative in hiring and collaboration to scale biological information from genes to ecosystems (http://egi.arizona.edu/partners)
