I am Michael Grünewald, the author of the texts on this site. I am also DevOps officer at quintly, tomorrow’s leading social media analytics solution. I previously worked as a math researcher (algebraic geometry and representation theory of reductive groups), as a financial mathematician and software developer.
Development and Operations
Cloud technologies shifted the frontier between hardware and software, allowing us to program tasks like “setup a computer in this computer center” or “change disks of that computer” instead of performing them physically. Together with the ongoing research in software development methodologies, which evolved to replace pharaonic projects carried out by a state by iterative developments attainable by an enthusiastic programmer, these two changes opened a world of opportunities to be taken.
As a financial mathematician at much-net AG I endorsed the roles of a quantitative analyst, supervising the pricing (including VaR, sensitivies and other more advanced metrics) of a large (more than 150) exotic derivatives, and of a programmer, optimizing PMS internal models for time and speed (LMM) and implementing new ones (quantum LMM).
I wrote my PhD thesis “Varieties of reductions for reductive algebraic groups” under the co-direction of Laurent Manivel and Nicolas Ressayre. This work contributes to the classification of Fano varieties, a crucial problem in birational geometry and contemporary physics, by investigating the varieties of reductions for a reductive algebraic group first defines by Atanas Iliev and Laurent Manivel.
After defending my PhD, I spent one year as a guest scientist at the MPIM and one year at the Hausdorff Center for Mathematics, where I constructed a universal family for the subgroups of an algebraic group (as an ind-variety).
