Solange Duhamel

Solange Duhamel is an Associate Professor in the Department of Molecular & Cellular Biology at the University of Arizona, where she leads the Duhamel Lab for Marine Microbiology and Biogeochemistry. Her research focuses on aquatic microbial communities, including their roles in biogeochemical transformations, adaptations to extreme environments, and responses to climate stressors like temperature increases. She integrates field studies with laboratory experiments and advanced techniques such as NanoSIMS for single-cell analysis.

Research Interests:

• Marine and freshwater microbial ecology
• Phosphorus and nitrogen cycling in oligotrophic systems
• Microbial adaptation to nutrient limitation and extreme environments
• Interactions between microbes and higher organisms (e.g., salamander-alga symbiosis)
• Application of flow cytometry and isotopic tracing in microbial studies
• Implications of microbial processes for planetary habitability

Scientific Trends: Recent publications emphasize phosphorus dynamics in marine systems, microbial responses to climate stressors, and interdisciplinary approaches to understanding nutrient cycling. Her work bridges ecology, biogeochemistry, and astrobiology, particularly through studies of extremophiles in Icelandic hydrothermal systems as Mars analogues.

Labs & Collaborations:

• Duhamel Lab for Marine Microbiology and Biogeochemistry
• Joint Faculty in Molecular & Cellular Biology
• Collaborations in satellite ocean color validation and BGC-Argo float data analysis
