Zu Gast bei CliSAP: Ivan Sudakov


Ivan Sudakov von der Universität Utah will neue Methoden der Mathematik und Physik für die Geowissenschaften entwickeln. Dazu forscht er als Gastwissenschaftler bei Prof. Valerio Lucarini in Mathematischer Modellierung, Statistischer Mechanik und Dynamischen Systemen.

Appreciates the support from the Federal Ministry of Education and Research: Ivan Sudakov.

You have participated in the Green Talents Competition. Since when are you interested in climate research? And why does it fascinate you?
The "Green Talents - International Forum for High Potentials in Sustainable Development" attracts every year 25 outstanding young scientists who research in the field of sustainability of our planet. I guess that interdisciplinary interaction between mathematics and climate science can make contribution to Sustainable Development. Indeed, mathematicians and theoretical physicists try to learn more about the challenges faced by our planet and the underlying mathematical problems. Currently, we should increase the research effort on these issues.
Why do you visit Hamburg and the Cluster of Excellence CliSAP?
It is very strong place for multidisciplinary collaboration that is quite important for solving of climate issues. The University has a long history of climate research.
Could you explain in easy words what you want to work on while you are at CliSAP?
Statistical physics offers an approach to climate change modeling that could dramatically reduce the time and brute-force computing that current simulation techniques require. The new approach focuses on description of energetic states (through Hamiltonian of a system) of typical patterns in the climate system (e.g., melt ponds on sea ice surface, tropical convection patterns etc.). Changing of energetic states of such patterns can lead to the changing of the state of the climate system. That looks like a phase transition. Moreover, applications of this approach can help to associate statistical physics with other mathematical methods for studying the critical phenomena in the climate system.

With whom do you work together?
I am working with Prof. Valerio Lucarini and his team. He is a world renowned expert in statistical physics for climate. We fist met in 2011, when he gave a short course in physics of climate. His course was very interesting. He can combine climate and modern physics and math. I am happy to get a chance to work with him.
What can your expertise in the field of mathematical models add to the Cluster?
CliSAP is a famous place for numerical models of climate. I guess here, my experience in applied dynamical systems will be useful for developing the climate tipping point theory which is based on very rigorous theoretical tools. This theory with combination of numerical climate simulations can give more information for policy-makers.

What can you take with you when you are going back home?
I guess this visit can help me to top up my jar of the knowledge in statistical physics.
Do you already have an image of future activities that may arise from your trip to Hamburg? Which scientific goals do you have?

First of all, we should complete at least a draft of the joint paper. In the future we will try to prepare a grant  proposal for the joint project in statistical physics of climate.
