Professor Kurt Langfeld

Visiting Professor

School of Computing, Electronics and Mathematics (NC) (Faculty of Science & Engineering (NC))

Role

I am Professor in Theoretical Physics at the School of Computing and Mathematics. I am the academic lead of the High-Performance -Computing Facility of the Faculty of Science & Environment. Since two years, I am the Director of the Doctoral Training Centre for Computing & Mathematics, and since May 2013, I am also the director of the research Centre for Mathematical Sciences (CMS). I am coordinating the research for our school and as such I contribute as a member of the School Executive Committee. 

Qualifications

I got my PhD in Physics from the Technical University of Munich
in 1991. My first years as a postdoc brought me to the Institue for
Theoretical Phyiscs at the University of Tuebingen, where I spent most
of my time as a researcher in Particle and High Energy Physics and as a
lecturer. I have benefited form (shorter) stays at international research
intitutions the CEA, Saclay, Paris to be mentioned in first place. I had
the opportunity to visit an Asian country being twice a visiting Professor at
KIAS, Seoul, South Korea. In 2003, I hold a chair of Theoretical Physics at
the University of Karlsruhe for half a year.

In 1999, I passed the "Habilitation" which is a German
certificate for excellent teaching skills. In 2005, I became Professor for
Theoretical Physics at the University of Tuebingen. In 2006, I joined 

Plymouth University. In April 2012, I was promoted to Professor in Theoretical 
Physics.
