Peter T. Doran

Peter T. Doran is an Adjunct Professor in the Department of Geology & Geophysics at Louisiana State University. His research focuses on understanding extreme environments in both Earth and space contexts, particularly Antarctic ecosystems and planetary protection challenges. Dr. Doran leads studies on Antarctic lake dynamics, hypersaline brine systems, and astrobiological field sites that serve as analogs for extraterrestrial environments.

Key research themes include:

• Climate change impacts on polar desert ecosystems
• Planetary protection policies for icy world exploration
• Biosignature preservation in evaporitic environments
• Microbial adaptation to polyextreme conditions

His work integrates limnology, geophysics, and astrobiology to address fundamental questions about life's limits on Earth and potential extraterrestrial habitats. Long-term field studies in Antarctica and Western Australia form the core of his observational and experimental research programs.
