I am a postdoctoral reseacher in the Department of Algebra at Charles University, Prague. My research is currently funded by the Primus grant “Categorical Knörrer periodicity, cluster categories and tensor triangulated geometry”, which also funds the research of Sebastian Opper (PI) and Jordan Williamson.
Between 08/2020 and 12/2022, I was a researcher on Liran Shaul's grant 'Cohen-Macaulay rings and their applications in higher algebra and topology'.
I completed a PhD in Pure Mathematics at the University of Manchester under the supervision of Prof. Mike Prest in 09/2019.
