CURRENT RESEARCH PROJECTS
1. How do microbial communities in thawing permafrost mediate carbon cycling, and feed back to climate change?  September 2010 - present

Approach: We are working with biogeochemists and modelers to examine carbon cycling across an in situ permafrost thaw gradient. We intensively monitor microbial community composition and metabolic activity (through 16S rRNA sequencing and meta-omics), carbon gas fluxes and isotope compositions (through an autochamber system with in-line quantum cascade laser spectroscopy), and porewater and bulk phase geochemistry (through standard methods and FT-ICR-MS), at the long-term field site of Stordalen Mire. The modelling component of our project examines scaling of biogeochemical and molecular inferences from the soil column and plot level to the ecosystem and region. Our lab leads the microbial metaproteomics and is heavily involved with the microbial community compositional analyses, and coordinates the field sampling campaigns. 

Co-investigators: Saleska Lab (Univ. of Arizona), Tyson Lab (Univ. of Queensland), Crill Lab (Stockholm Univ.), Chanton Lab (Florida State Univ.), Li and Frolking Labs (Univ. of New Hampshire), and Abisko Research Station in Sweden

 

2. How do near-shore microbial and viral communities “buffer” reef systems from terrestrial pollutants? January 2011 - present

Approach: This interdisciplinary effort is the synthetic vision of microbial and viral ecologists, marine chemists, coral biologists, hydrodynamic modelers, and ecosystem modelers, under lead PI Gene Tyson (University of Queensland). We are working to test whether near-shore microbial and viral communities sequester and/or transform terrestrial-derived pollutants and thereby “buffer” from the Reef from their full effects. My lab is leading the analysis of the viral communities in the context of the microbial community diversity and pollution metadata.

Co-investigators: Tyson Lab (Univ. of Queensland), Sullivan Lab (UA), Bourne and Schaffelke Labs (Australian Institute for Marine Science)

 

3. What are the systems-level effects of compost-based management of turfgrass? May 2012 - present

Approach: This interdisciplinary UA-focused project leverages the UA Organic Land Stewardship Program to investigate the whole-system impacts of compost treatment on turfgrass, expanding the more traditional metrics of soil nutrient cycling and water holding capacity to include greenhouse gas flux, microbial and macrobial community response, and plant-pathogen interactions. I coordinate this effort, and my lab leads the collection, processing, sequencing and analyses of the microbial communities. 

Co-investigators: Joost van Haren (UA), Troy Hollar (Merlin Organics) Katerina Donstova (UA), Mitch Pavao-Zuckerman (UA).
