Introduction of Two Extended Post-Doctoral Positions in Mathematics, a Premiere for INSMI


This year, for the first time, the National Institute for Mathematical Sciences and their Interactions (INSMI) has initiated a call for applications, offering two extended post-doctoral positions, each lasting three years. The recipients, Maëva Ostermann and Oğuz Şavk, will join the Paul Painlevé Laboratory (University of Lille) and the Jean Leray Mathematics Laboratory (University of Nantes), respectively, at the end of the summer.

In 2023, INSMI launched two calls for extended post-doctoral positions in mathematics.

While post-doctoral positions are a common practice worldwide, France typically offers very few extended post-docs, especially in mathematics, meaning positions that last for three years. This reluctance to open up extended post-doctoral opportunities, largely due to their financial cost, has limited the attractiveness of French research on the global stage.

For the first time this year, INSMI took a significant step to address this issue. On February 23, 2023, they launched a call for applications for two post-doctoral positions, each spanning three years, to be conducted within one of its affiliated laboratories. This call was communicated to all unit directors at INSMI, with a deadline for applications set on April 3. In total, 74 applications were received, including 13 from female candidates.

The successful candidates for the 2023 campaign, Maëva Ostermann and Oğuz Şavk, are set to contribute to their respective laboratories, bringing fresh perspectives and expertise to the Paul Painlevé Laboratory at the University of Lille and the Jean Leray Mathematics Laboratory at the University of Nantes.

Maëva Ostermann completed her PhD at Laval University in Quebec, Canada, under the supervision of Thomas Ransford. Her thesis, conducted in functional analysis and operator theory, is titled "Estimation of Operator Function Norms." Since defending her dissertation, she has been working as a lecturer in the Department of Mathematics and Statistics, where she teaches mathematics courses to engineering students as well as to students at the School of Actuarial Science at Laval University.

In terms of her research interests: Maëva Ostermann specializes in functional analysis, operator theory, and complex analysis. More specifically, she is engaged in problems related to digital imaging, K-spectral sets, Crouzeix's conjecture, dilation theory, Banach algebras, C*-algebras, von Neumann algebras, Kreiss's theorem, pseudospectra, and Faber operators.

Oğuz Şavk earned his Ph.D. from Boğaziçi University in Turkey in the spring of 2023, with Çağrı Karakurt as his advisor. He served as a teaching assistant from the fall of 2019 until the summer of 2022. He was a visiting research student at the Max Planck Institute for Mathematics in Bonn from January to June 2022. Following this, he received a Fulbright grant from the Turkish Commission to visit Stanford University as a visiting research student from September 2022 to May 2023.

Oğuz Şavk specializes in low-dimensional topology and classical algebraic geometry. In particular, his research focuses on 3- and 4-manifolds, as well as complex surfaces, utilizing techniques from Floer theory, cobordism homology group invariants, Kirby calculus, and singularity theory.
