Research Interests

Materials Characterisation and Molecular Processes

The core of my work is in the characterisation of condensed matter in relation to the pharmaceutical manufacturing. I am in particular interested in characterisation of supercooled liquids and glasses and molecular processes responsible for their crystallisation. In this context, the terahertz spectroscopy is a lucrative technique sensitive mainly to the inter-molecular dynamics. The research spans both understanding fundamental molecular excitations, such as molecular relaxations and librations, as well as the usability of the terahertz spectroscopy in industry, for example, for controlling crystallisation kinetics.

Development of Terahertz Technology

I have also a keen interest in developing the terahertz technology further. Together in a collaboration with the Semiconductor Physics Group at the University of Cambridge and the Terahertz Laboratories at the University of Southampton I am working on characterisation of novel terahertz sources based on the quantum cascade laser structures.

In collaboration with Laboratory of Terahertz Spectroscopy in Prague, Czech Republic, we have developed also new devices based on the semiconductor metamaterials, such as wave plates operating at terahertz frequencies or a photonic crystal that may be used for terahertz sensing of sub-microlitre amount of liquids.

Other Activities


I actively contribute to the teaching at the University of Cambridge. I was elected to a teaching Bye-Fellowship at Fitzwilliam College where I supervise undergraduates in Physics. Further to that I mentor Chemical Engineering research projects in our laboratory.


Whenever I have an opportunity I like to join new entrepreneurship activities, in particular those where I can employ my technical expertise in a broader context. This my interest developed mainly after joining CUTEC and CUFIS during my studies and gaining a sense for enterprise. A nice example is my participation in i-Teams project where our team helped to commercialise a novel micro-cantilevers technology able to measure the viscosity of blood and other fluids.
