    CV

    Currently, I am a postdoc at the Institute of Algebra and Number Theory at the Department of Mathematics - University of Stuttgart.

    From November 2022 to September 2023, I was a postdoc at the Max Planck Institute for Mathematics in Bonn.

    Until October 2022 I was a research assistant in the field of representation theory at the Institute of Algebra and Number Theory at the Department of Mathematics - University of Stuttgart.

    In October 2021, I defended my PhD dissertation in the field of representation theory in Stuttgart.

    The title of my doctoral thesis is Algebraic analogues of resolution of singularities, quasi-hereditary covers and Schur algebras, supervised by Prof. Dr. Steffen Koenig.

    From September 2018 to August 2021 my research was funded by Studienstiftung des deutschen Volkes.

    In July 2017, I obtained my master's degree in pure mathematics at University of Coimbra.

    The topic of my master's thesis was Schur-Weyl duality (available online: here), supervised by Prof. Dr. Ana Paula Santana and Prof. Dr. Ivan Yudin.

    Here is my ORCID profile. Here is a list of conferences I have attended.
