Magdalena Mayr

Magdalena Mayr is a Research Fellow in Biology and Biological Engineering at the California Institute of Technology (Caltech), affiliated with the Division of Geological and Planetary Sciences. Her research focuses on microbial ecology, particularly in methane oxidation processes in aquatic and marine environments. She explores microbial communities in extreme habitats such as seep carbonates, stratified lakes, and deep-sea sediments, employing advanced methods like single-cell analysis and combination buffer techniques for microbial cell extraction.

Her work bridges environmental microbiology with biogeochemical cycles, emphasizing microbial responses to environmental changes, such as lake overturn events and human impacts on river-floodplain systems. She has contributed to understanding the role of methanotrophs in mitigating methane emissions and the dynamics of microbial succession in diverse ecosystems.

Key projects include studying microbial diversity in the sulfate-methane transition zone, anaerobic methane oxidation in seep carbonates, and the ecology of the aquatic methane filter in stratified lakes. Her findings highlight the interplay between microbial activity, nutrient cycles, and ecosystem health.

Magdalena has no listed scientific awards but has published extensively on microbial communities and methane cycling. She collaborates with interdisciplinary teams to address global challenges in climate science and environmental restoration.
