My research focuses on tuning correlations in metals, insulators, and semiconductors with hydrostatic pressure. Using transport, thermodynamic, and magnetic measurements I aim to enhance our understanding of electronic behavior.

One focus of my research is to map the evolution of the Fermi surface whilst tuning materials from one ground state into another, e.g. from an antiferromagnet into a paramagnet. Strong correlations have been observed in such cases to lead to novel states like unconventional superconductivity. Here, I utilize quantum oscillation measurements to unravel the underlying electronic structure changes which can provide important input to theories of unconventional superconductivity.


I conducted my PhD research project at the Max-Planck Institute for Chemical Physics of Solids and obtained a Dr. rer. nat. from the Technical University Dresden, Germany with distinction in 2009. There, I performed high-resolution Hall effect measurements in crossed magnetic fields and established a Fermi surface reconstrution in the prototypical quantum critical material YbRh2Si2

From 2010 to 2013 I worked as a research fellow at the University of Cambridge first on a Feodor-Lynen fellowship of the Alexander von Humboldt foundation and later on a Marie Curie fellowship of the European Research Council. My research here focused on electronic structure studies using quantum oscillation measurements in combination with band structure calculations. In addition, I pioneered new pressure techniques which I utilized to perform Fermi surface studies under pressure.

In 2013 I joined the University of Bristol as a lecturer.
