About
Gerda’s BEng and MEng projects analysed development of Diamond Like Carbon (DLC) coatings for engine components. In her MEng project, a correlation was established between the deposition process chemistry, coating friction performance and resistance to impact. In 2018 Gerda joined the Institute of Functional Surfaces at the University of Leeds (UK) to work on a PhD supervised by Prof. Ardian Morina, Prof. Anne Neville and industrial advisor Benoit Thiebaut from TotalEnergies (France). During her PhD, Gerda was involved in studying the performance of engine tribological components. In collaboration with industry, the PhD investigated the underlying reactions of lubricant additives with the aim to improve lubricant formulation for passenger cars. Gerda has always been involved in outreach and teaching at the various academic institutions that she has attended. At Leeds she taught courses on fundamentals of Raman Spectroscopy and tribometer testing methodology while supervising and managing laboratory responsibilities. Currently Gerda works in collaborative DFG funded project with Institute of Fluid Mechanics (ISTM). The project aims to improve the understanding of macrogemetry and surface texturing influence on the tribological performance. To achieve this, Gerda is contributing towards development of the digital twin of the experimental tribosystem by providing an experimental characterisation of the tribological response.
She has also been recognised widely for her excellence in approach, receiving multiple awards and scholarships for her academic achievements and research potential. Gerda’s contribution in the fields of tribology, lubrication and wear has been awarded Institute of Mechanical Engineers (United Kingdom, London) Tribology Bronze Medal.
