I was born in Würzburg, Germany, in 1968. I received my Diploma in physics from the University of Kaiserslautern in 1992, and my PhD in physics from the University of Karlsruhe in 1995. From 1995 to 1998, I was assistant research professor at the Mikroelektronik Centret, Denmark. From 1998 to 2004, I was with the University of Dortmund, where I received my Habilitation in 2003. In 2004 I was appointed Senior Lecturer in the School of Physics, Cardiff University, promoted to Reader in 2006 and to Personal Chair in 2007.

I hold first- and second-year tutorials, and supervise 3rd and 4th year project students.

I'm presently (co-)supervising four post-doctoral fellows and four post-graduate students.

My current research interests are

  1. characterisation and ultrafast spectroscopy of semiconductor nanostructures, microcavities, and quantum-dot optical amplifiers.
  2. application of optical spectroscopy to life-science, focussing on the techniques of coherent anti-stokes Raman scattering (CARS) microscopy, fluorescent resonant transfer, label-free optical biosensors using microcavities, and statistical analysis of individual quantum emitters such as colloidal quantum dots.
