Current Research

My current effort is devoted to reproducing the Earth's magnetic field in a computer. The geomagnetic field is generated by a dynamo process inside the Earth's core where flow of liquid iron causes electromagnetic induction. My current research is to analyze the flow and the electromagnetic field inside the core by means of massively parallel computing. To predict the behavior of the geomagnetic field is an important key to understand the Earth's evolution in the past and the surficial environment in the future.
