I am a PhD student supervised by Anastasios Stefanou in the Mathematical Foundations of Data Analysis (MGDA) group, which is part of the Institute for Algebra, Geometry, Topology and their Applications at the University of Bremen.
My interests cover combinatorial commutative algebra and methods of relative homological algebra for understanding multigraded modules and associated invariants, in particular those with applications in generalized persistence theory and topological data analysis.
In the area of relative homological algebra I work with exact structures that arise from combinatorial changes of rings to construct new homological invariants for persistence modules.
You can find more information about my work and background in my Curriculum Vitae.
