Miroslav Rapcak
CERN
Bio:
I am currently a senior research fellow at the Department of Theoretical Physics in CERN. Previously, I was a postdoctoral fellow at The Berkeley Center for Theoretical Physics. I received my PhD in 2019 from the University of Waterloo working at Perimeter Institute for Theoretical Physics under the supervision of Davide Gaiotto.
I am interested in mathematical aspects of string theory and quantum field theory. My current research focuses mostly on discovering new applications of supersymmetric gauge theories and string theory leading to novel insights in geometric representation theory. I am also interested in applications of representation theory of algebras in holography, knot theory, geometric Langlands program and other areas. In the past, I worked on integrability of defects in conformal field theories and construction of classical solutions in bosonic string field theory.
