Scientific Collaborators

Jennifer Pett-Ridge
Jennifer is interested in warming effects on microbial community composition and function.
Karis J. McFarlane
Karis J. Mcfarlane
Lawrence Livermore National Laboratory
Karis is a forest soil scientist who studies carbon cycling in soils and ecosystems. She is an expert in the use of radiocarbon as an indicator of soil carbon longevity and the contribution of different sources of carbon to greenhouse gas fluxes. At TRACE, Karis is helping the team identify whether experimental warming increases the decomposition of soil organic matter and loss of soil carbon back to the atmosphere through soil respiration.
Tanya Hawley Matlaga, Patricia Burrowes, Janelle Peña
Tanya Hawley Matlaga, Patricia Burrowes, and Janelle Peña 
Susquehanna University, University of Puerto Rico-Río Piedras
Tanya, Patricia and Janelle are amphibian ecologists. They are interested in seeing how the common coquí frogs respond to climate warming. More specifically, they are investigating how frog growth, survival and movement differ in heated and treatment plots using mark-recapture methods.
David Matlaga
David Matlaga  
Susquehanna University
David studies applied aspects of understory community and population ecology. Changes to the herbaceous plant community in response to the warming treatments and hurricanes has been studied by David and several other collaborators.
Bénédicte Bachelot
Bénédicte Bachelot is a tropical community ecologist interested in the processes promoting high tree diversity in the tropics. Béné has been collaborating on a seedling demography and herbivory study in the TRACE plots.

Brent Newman
Brent Newman 
Los Alamos National Laboratory
Brent Newman is a hydrogeologist at Los Alamos National Lab. He installed macro-Rhizon samplers in the TRACE plots to monitor soil water chemistry and stable isotopes at three depths below ground.
Grizelle González
Grizelle González
USDA Forest Service, International Institute of Tropical Forestry
Grizelle Gonzalez is the IITF Director and an invaluable member of the team! Grizelle was particularly instrumental in facilitating the power upgrades and installation of infrastructure for the in situ field warming experiment in El Yunque National Forest. Grizelle's research is focused in macroarthropods and decomposition dynamics.

Xiaojuan Yang 
Oak Ridge National Laboratory
Xiaojuan Yang is an Earth system modeler focusing on nutrient cycling and carbon-water-nutrient interactions in terrestrial ecosystems in the context of global change. She will coordinate the modeling activities of the project, help to set up site model simulations and evaluations, incorporate experimental results into models and perform ecosystem-level simulations.

Anthony Walker 
Oak Ridge National Laboratory
Anthony is a terrestrial ecosystem ecologist that uses computer models to help interpret ecosystem responses observed in global change experiments. Anthony is excited to join the fantastic team of TRACE researchers and to help apply ELM-FATES (a size-structured, ecosystem function model) to integrating diverse data from the warming experiment.
Brooke Osborne
Brooke Osborne
United States Geological Survey 
Brooke is a biogeochemist and ecosystem ecologist interested in the consequences of global change for tropical forest carbon and nutrient cycling. With TRACE, she is especially interested in deep soil carbon and the effects of warming for the quantity and quality of leaf litter leachate on the forest floor.
Michala Phillips
Michala Phillips 
United States Geological Survey
Michala is an ecologist working at the interface of community and ecosystem ecology, with a keen interest in how climate change is altering soil microbial communities and the processes they govern.
