Dr Costis Papageorgakis

Profile

I am a Royal Society University Research Fellow at the Centre for Research in String Theory, School of Physics and Astronomy. My work has focussed on various aspects of supersymmetric gauge theories and their relation to String/M-theory.

I hold an undergraduate diploma from the University of Patras (Greece), an MSc from Durham University and a PhD from Queen Mary University of London. I have previously held postdoctoral positions at the Tata Institute of Fundamental Research (India), King's College London and Rutgers University (USA). 

Teaching

I teach the MSc/MSci course "Differential Geometry in Theoretical Physics" (DGTP) over the first semester of the 2020-2021 academic year.

I am a Fellow of Advance HE.

Research

Research Interests:

I am broadly interested in the study of D-brane and M-brane dynamics, in string and M-theory respectively, as well as the structure of their associated supersymmetric/superconformal gauge theories. In the past I have worked towards understanding multiple M2-branes in terms of superconformal Chern-Simons-matter theory in three dimensions, and multiple M5-branes through the superconformal (2,0) theory in six dimensions.

My current research focusses on various aspects of superconformal field theories in diverse dimensions. A broad toolkit of approaches and techniques can be used to that effect, including the study of anomalies, superconformal indices and exact methods such as supersymmetric localisation. I am also interested in the dynamics of solitons undergoing acceleration.
