School of Physics and Astronomy, Professor

Biography

Peter Wahl is a Professor of Physics in the School of Physics and Astronomy. He graduated with a diploma in Physics in 2001 after studying at the Universities of Bonn and Lausanne. Peter went on to pursue a PhD degree in Physics at the Max Planck Institute of Solid State Research in Stuttgart, and graduated in 2005. After stays in Aarhus in Denmark and, with a Feodor-Lynen fellowship, at Cornell University in the US, he returned to Germany, where he was awarded and led an independent research group at the Max Planck Institute for Solid State Research, developing advanced low temperature microscopes to study quantum materials. In 2012, he was appointed as a Reader in Experimental Condensed Matter Physics at the University of St Andrews. Since 2018, he is a Professor and Director of Research of the School of Physics and Astronomy. His research aims to identify new materials for future information technologies, by using atomic-scale imaging and spectroscopy to understand their properties and enable controlling them. The group has developed and now operates a suite of bespoke instrumentation that provides microscopic insights into the electronic states in these materials, with the aim to make them amenable for new, more energy-efficient, technologies.
