Short Bio

Cynthia Kallenbach’s research integrates soil ecology and biogeochemistry to understand soil organic matter turnover and accumulation and microbial-plant interactions affecting carbon and nutrient cycling under land use and global change. She received her BSc degree (Geography) from Sonoma State University, California. She has two MSc from University of California-Davis in International Agriculture Development and in Soil Biogeochemistry, and completed her PhD from the University of New Hampshire in Earth and Environmental Science. Before coming to McGill, she was a United States Department of Agriculture (USDA) postdoctoral fellow at Colorado State University.

Awards and Recognitions

Active Affiliation

Review board - Biogeochemistry

Research Interests

Kallenbach’s research program focuses on identifying and explaining the fundamental ecological and biogeochemical processes that characterize soil carbon and nutrient cycling, especially under managed ecosystems such as croplands. How soil microbial communities effect plant litter decomposition dynamics and rhizosphere processes, their influences on soil organic matter formation and stabilization, and microbial functional responses to agricultural management and global change are specifically considered. The program uses an integrated approach, combining lab, greenhouse, and field-based studies with advanced analytical measurements (molecular microbiology, stable isotopes, and molecular chemical fingerprinting). Knowledge gained is used to help inform the development of agricultural management scenarios that are both environmentally sustainable and productive.

Current Research

1) Evaluating the impacts of altered precipitation (drought and seasonal flooding) on soil biogeochemistry and soil microbial functional responses

2) Crop rotational diversity and cover crop impacts on soil organic matter and soil microbial communities

3) Integration of microbial drivers and geochemistry to understand permafrost carbon cycling

4) Identifying key microbial groups and their functional traits that influence soil organic matter chemistry and accumulation under different selection environments
