Research Interests

The oceans are a key element of the global climate system. Ocean currents redistribute vast amounts of energy, freshwater and tracers like carbon dioxide, thereby strongly affecting the global climate. The abyssal oceans, although mostly separated from upper ocean and atmosphere by strong density gradients, play an important role in this system. Deep-water formation at high latitudes, and mixing in the ocean interior, connect abyss and upper-ocean to form the so-called Meridional Overturning Circulation (MOC). My research is dedicated to assessing the current state of the MOC and to advance the understanding of physical processes that drive and modify it, especially in the abyss. Here, density driven overflows can lead to turbulent mixing, an important process for the closure of the overturning circulation. I focus my scientific work on the collection of in-situ observations, a challenging task at great oceanic depths, and the processing and interpretation of these data. The latter often incorporates theory, numerical simulations and observations that are developed, carried out and collected by other researchers.
