PhD

 I am currently a PhD student in Felix Finster's group in the Faculty of Mathematics at the University of Regensburg.

In my PhD, I work with the Theory of Causal Fermion Systems, further information about which can be found in this Wikipedia article or in this introductory article. Also, I recommend this talk or the recording of a spring school which I have co-organized recently.

In a nutshell, the goal of my PhD is to show that in a limit of the CFS Theory, the dynamics of the wave-functions correspond essentially to Continuous Spontaneous Collapse models of Quantum Theory.

I gratefully acknowledge the support of the Studienstiftung des Deutschen Volkes.

Also, I am very grateful for having the chance to visit Prof. Carlo Rovelli and his group in the CPT, Marseille (May 2016) and Prof. Shing-Tung Yau at the CMSA in Harvard (September-November 2016).
