Julien Emile-Geay

Julien Emile-Geay is a Professor of Earth Sciences at the University of Southern California (USC), affiliated with the Dornsife College of Letters, Arts and Sciences. His research focuses on understanding climate variability on human-relevant timescales, blending data and models to explore natural and anthropogenic climate drivers. He leads initiatives such as the Last Millennium Reanalysis and the LinkedEarth project, emphasizing co-equal integration of data and models in paleoclimate studies.

Education:

• Ph.D. Climate Dynamics, Columbia University, 2006
• M.S. Dynamics of Atmospheres and Oceans, École Normale Supérieure, 2001
• B.S. Earth Sciences, École Normale Supérieure, 1999

Research Interests: Climate Science, Paleoclimatology, Data Analysis, and Data Science. Specific areas include ENSO dynamics, solar-climate interactions, and low-frequency climate variability. He develops computational tools for climate reconstruction and advocates for reliable data inference in the face of misinformation.

Affiliations: Fellow at the Center for Applied Mathematical Sciences and Affiliated Faculty at the Information Sciences Institute.

Contributions: Pioneered frameworks like cfr and Pyleoclim for paleoclimate analysis, and co-edited global databases such as CoralHydro2k. His work bridges climate science with interdisciplinary collaboration and open-source software.
