Carlie Pietsch

Carlie Pietsch in the field My research focuses on paleontology and deep time marine biology. The 菠菜网lol正规平台 Paleontology lab group combines geologic observations with marine ecology and evolution to interpret the history of life on Earth with a focus on mollusks (clams and snails) and extreme climate change events. I am particularly interested in the disconnect between recovery pace and progress at local and global scales following mass extinction events. My research on extreme climate events serves as both an approximation of what we might expect as a result of modern climate change and as a window into the role of climate on evolutionary trajectories. My students and I conduct fieldwork to document environmental changes and collect fossil samples. We also delve into museum collections and fossil databases. We reconstruct paleoenvironmental changes using microscopic changes in sediments and fossils, stable isotope geochemistry, as well as physical and chemical variations in mollusk shell growth.

Education

  • Ph.D. 2015, University of Southern California

Research Interests

  • As a paleontologist, I study changes in fossil assemblages, sediments, and geochemistry to determine how extreme climate intervals in Earth's history effect the paleoecology and evolution of marine communities.

Recent Classes

  • Paleontology (GEOL/BIOL 142)
