Matthew Lachniet

Professor of Geology
Expertise: Climate Change, Quaternary Geology, Paleoclimatology

Biography

Matthew Lachniet, a professor in the department of geoscience, focuses on understanding the controls on Earth’s climate on time scales ranging from seasonal to hundreds of thousands of years, with a particular focus on tropical, desert southwest, and arctic past climates. These data inform understanding of modern and anthropogenic climate change.

Lachniet uses light stable and radiogenic isotope geochemistry, hydrology, speleology, glacial geology, geomorphology, and the sedimentary record to answer questions of paleoenvironmental and paleoclimatic change. His primary research areas are Costa Rica, Panama, Mexico, Alaska, and the Great Basin. His research goal is to constrain past climate changes in these regions using proxy records. He is particularly interested in generating rainfall histories for Central America and to evaluate the climate forcings of climate change and variability in the neotropics.

Scientists are studying mineral deposits in the caves of the Grand Canyon to understand the impacts of climate change.
The Week
They chose an ancient calcium projection, called stalagmite, from the floor of an undisturbed Grand Canyon cave and studied its geochemistry. The research team was led by the University of Nevada, Las Vegas, and included the University of New Mexico.
