Dr. Claus Goetz
Since November 2016 I am a Post-Doc in Prof. Dr. A. Iske's working group. I am part of the collaborative research center TRR 181 "Energy Transfers in Atmosphere and Ocean". Within project M5: "Reducing spurious diapycnal mixing in ocean models" I am working on the development and analysis of high-order advection methods relying on high-order flux evaluation.
I am the organizer of the
Lothar Collatz Seminar.
Previously, until October 2016, I was a Post-Doc at the University of
Trento (Italy).
