Biography

Following undergraduate studies at the University of Bonn, I obtained an MSc in Chemistry from the University of Hamburg. During this period, I spent time at the University of Bangor as an ERASMUS student, working with Dr Ian Butler on ferrocene chemistry. I then completed a D.Phil. at the University of Oxford under the supervision of Prof. John E. McGrady in Computational Inorganic Chemistry. Subsequently, I worked as a postdoctoral researcher in Frank Neese"s group at the Max Planck Institute for Chemical Energy Conversion. I later returned to the UK to take up a postdoctoral position with Prof. Stuart Macgregor at Heriot-Watt University, during which time I also visited the Universities of Zurich and Ghent. After serving as a Lecturer in Inorganic Chemistry at Maynooth University for several years, I was appointed Schuler Assistant Professor of Computational Chemistry and Artificial Intelligence at Trinity College Dublin in 2025.

Research Expertise

My group's research interest centre around transition metal, organometallic, main group and bioinorganic chemistry. Computational quantum chemistry and theoretical spectroscopy are central in solving chemical problems related to these thematic areas. Our aim is to model chemical structure and reactivity and relate to the electronic structures of systems with relevance to homogenous and heterogeneous catalysis. Methods that we specialise in include density functional theory, ab initio wavefunction theory and hybrid QM/MM approaches. A definitely feature of our work is the close interaction with experimentalists.
