Postdoctoral position starting september 2017

We have a postdoctoral position available in arithmetic and algebraic geometry available, funded by the ERC project AlgTateGro. We are looking for a postdoctoral researcher working in any of the following fields: moduli spaces of sheaves on algebraic varieties, birational geometry, algebraic cycles, both in Hodge theory and arithmetic geometry, motives, Arakelov geometry, diophantine approximation in relation to algebraic geometry, aspects of transcendental number theory. The position has no teaching duty and can be held for up to three years. Send a CV and a research statements to my email address by january 15th. Recommendation letters are encouraged and should be sent by the end of january. More details are available on the euraxess website.
