Joern Callies

Joern Callies is a Professor of Oceanography and Environmental Science at the California Institute of Technology (Caltech), affiliated with the Division of Geological and Planetary Sciences and the Department of Environmental Science and Engineering. He holds an M.S. from the University of Hamburg (Germany, 2011) and a Ph.D. from MIT (2015). His research focuses on ocean circulation dynamics, using in situ and satellite observations, dynamical models, and numerical simulations to understand climate regulation mechanisms.

Education:

• M.S., University of Hamburg, Germany, 2011
• Ph.D., Massachusetts Institute of Technology, 2015

Research Interests: Dr. Callies investigates submesoscale and mesoscale ocean processes, including turbulence, eddy dynamics, and abyssal circulation. His work emphasizes the interplay between observational data and theoretical models to uncover governing principles of oceanic fluid dynamics.

Key Research Themes (2023–2025):

• Seismic oceanography for temperature monitoring
• Submesoscale eddy impacts on heat flux and turbulence
• Abyssal T-waves and deep-ocean dynamics
• Advances in airborne and fiber-optic observational techniques

Lab/Team: His research group collaborates with international institutions, deploying cutting-edge observational platforms like autonomous floats and satellite altimeters to study oceanic processes at high resolution.
