Jonathan is a professor at OSU who studies turbulence and small-scale fluid dynamical processes and how these transport heat, momentum and energy through the global oceans. Small-scale turbulence is what directly controls the heat that flows across boundaries (like the air-sea and ocean-ice interfaces), and thus affects both local dynamics (the rate at which a glacier melts) and the global climate system, which evolves through the cumulative effect of processes on all scales.
To study these types of physics, new types of specialized instruments are often required. For Jonathan, one of the best parts of his career is that he gets to work with a diverse team of students, engineers and scientists to do fieldwork in exciting places, on important topics, and using new technologies that get developed in his lab.
