About

My name is Svetlana Dubinkina, and I am a mathematician

Earth sciences provide with an endless source of fascinating problems related to weather, climate, subsurface structure of the Earth, to name a few. A question that could be posed is, “Are the changes predictable?” Because then we could stop (reverse) the climate change, predict how much wind energy we are going to produce next 10 years, how much oil or gas is still below the surface and where it is located. To answer these questions requires an interdisciplinary collaboration between scientists from mathematics, physics, climatology, geology, and engineering.

Research

I am a Senior Researcher at the Dutch National Center for Mathematics and Computer Science. My research interests include numerical methods, statistical mechanics, data assimilation, paleoclimate, subsurface flow, wind energy, pipe flow.

    Ultimate goals of running projects are
  • ― to develop a novel data assimilation method that could tackle the problem of predicting climatological evens such as Little Ice Age that happened roughly 1400–1700 AD and a switch between two paths of Kuroshio current that happens abruptly and has a significant influence on local economics;
  • ― to predict the evolution of subsurface flows given a few local observations from wells and as a consequence to predict production rates of gas;
  • ― to predict formation of slugs in the pipes and their propagation, since those can cause unstable, intermittent production which can even kill a producing well;
  • ― to predict severe magnetic storms a few hours in advance in order to put a satellite in a sleeping mode such that the satellite would not be destroyed.
