Dr. Sepúlveda Steiner is an engineer and a scientist with a great passion for the environment and its preservation. He did his PhD at École Polytechnique Fédérale de Lausanne (EPFL), Switzerland, where he worked with A. Wüest and D. Bouffard on turbulence in stratified flows. His main research interest is physical limnology. He strives to understand aquatic physical processes entailing ecological responses (and vice versa), combining novel field measurement techniques like microstructure turbulence, underwater robotic platforms, and acoustics with modeling. Before joining UC Davis and TERC, he did a postdoc at Eawag (Swiss Federal Institute of Aquatic Science and Technology), where he worked on several multidisciplinary research linking aquatic physics and biogeochemistry. Currently, he is working on a project to unravel the effects of basin-scale gyres on lake water heterogeneity at Lake Tahoe using underwater gliders in collaboration with Alex Forrest, under a Swiss-NSF postdoc Mobility Fellowship. He also supports TERC research in the Arctic and Antarctica.
