I was born in Bratislava, then Czechoslovakia and moved to Germany at the age of four, where I grew up. I read Chemistry at St Hugh’s College Oxford until 2002 and did a PhD at the University of California, Berkeley with Rich Mathies in ultrafast spectroscopy before moving to ETH Zurich to work with Vahid Sandoghdar on nano-optics. After returning to Oxford in 2010, I was elected to a tutorial fellowship at Exeter College in 2011 and promoted to Full Professor in 2016. Recent awards include those by the Royal Society of Chemistry (Harrison-Meldola 2011 and Marlow 2015), the European Biophysical Society Association (Young Investigator Medal 2017), a Royal Society Wolfson Research Merit Award (2018), the Klung-Wilhelmy Award (2018) selection as a UK Blavatnik Awardee (2019), and the Medal for Light Microscopy by the Royal Microscopical Society (2021). I have been supported by ERC Starting, Proof of Concept and Consolidator Grants, as well as Career Acceleration and Leadership Fellowships by the EPSRC. In 2018, I founded Refeyn Ltd, where I am a non-executive director.


We develop new optical methods with applications in biophysical chemistry, molecular biophysics and across the broader life sciences. Currently, we focus on mass photometry, light-scattering-based detection, imaging and mass measurement of single biomolecules in solution. Our goal is to transform our ability to monitor and quantify biomolecular processes – ultimately delivering technologies that enable us to directly observe biomolecules in action. We foster a strongly collaborative approach to research, and are based in the Kavli centre for nanoscale discovery, a highly interdisciplinary environment across departments, disciplines and divisions. Work in our group falls in two major categories: 1. Development of novel optical hardware and analysis approaches to enable new measurement modalities. 2. Application of our methodologies with a focus on mechanistic investigations of biomolecular interactions and assembly.


At Exeter I teach all aspects of Physical Chemistry throughout the entire undergraduate degree.
