Biography
Currently I am a Marie Curie fellow at the TOMCAT beamline at the Swiss Light Source. I hold a PhD degree in Chemical Engineering from University of Chemistry and Technology in Prague. Topic of my thesis was development of mathematical models to understand behaviour of hierarchical pore structures for application in heterogeneous catalysis. During my PhD, I carried out internships at Imperial College London, TU Berlin and Johnson Matthey. After finishing my degree I worked as a scientist for 5 years in the technology centre of Johnson Matthey developing novel catalytic systems to tackle automotive emissions. I joined TOMCAT group in 2018.
Research Interests
I am interested to study evolution of multiphase systems in 4D (space and time) to understand interactions between solid, liquid and gas. I have been developing experimental cells to perform such experiments under controlled temperature, pressure and gas environment. I have been also exploring the possibilities of automatic image processing and segmentation due to large amount of data collected during a time-resolved experiment. The applications I am currently working on include:
- catalyst manufacturing process: coating deposition & drying
- pharmaceutical applications: liquid/melt tablet impregnation & tablet disintegration
- gas flow through porous structures
I help users at the TOMCAT beamline to carry out their experiments, which are often in-situ & time-resolved.
