Volker Schomerus holds a joint position as a Senior Researcher in the DESY Theory Group, and a Professor of Mathematical Physics at Universität Hamburg. His work focuses on string theory at the interface to high energy physics, mathematics and statistical physics, for which he has received several distinctions, including the Guy-Lussac–Humboldt award in 2010. He is also co-author of the monograph Boundary Conformal Field Theory and the World-Sheet Approach to D-Branes (Cambridge, 2013).

'This book successfully captures the essence of string theory every theoretical physicist should know. I would like to use it in my next course on string theory at Caltech!' Hirosi Ooguri, California Institute of Technology
