PALEO² LAB

Paleoceanography & Paleoclimatology at the University of Arizona
We study atmospheric and oceanic variability under past and future climate change

Dr. Kaustubh Thirumalai

Welcome—my research group at the Department of Geosciences at the University of Arizona studies climate variability across Earth’s history and future. We are interested in the causes and mechanisms of oceanic and atmospheric variations and how such information can help anticipate future impacts of global change. To do so, we use a combination of modern observations, (bio)geochemical measurements, and climate simulations. We are motivated to use the geological record as a laboratory to fully understand the machinery of Earth’s climate system and explore its response to perturbations.

Ongoing research projects include assessing past and future El Niño variability, reconstructing past monsoon rainfall intensity and its impacts on ocean biogeochemistry, and exploring the role of ocean circulation anomalies under global change.
