Kathleen Johnson

Physics Sciences, Earth System Science
Develops high-resolution records of past climate (paleoclimate) using speleothems (cave calcite formations) and other archives from China, Laos, California and other regions.
Studies modern cave systems to assess the environmental controls on speleothem geochemistry and improve interpretation of paleoclimate records based on stable isotopes, trace elements and radiocarbon.
Utilizes instrumental climate data, paleoclimate data and isotope-enabled climate models to investigate the spatial and temporal patterns of natural climate variability, calibrate paleoclimate proxy data and investigate mechanisms of past climate variability.

Expert in caves, climate change, past climate variability and geochemistry.
