Educational background

The main research interest is in applying advanced numerical methods tailored to the problem at hand. The research subjects are complex phenomena with bottom-up simulation techniques and analysing the phenomena (up-bottom). Subjects where I worked include simulation of pollutant dispersion in atmosphere, thermophoretic effects for aerosols, quantum particles (electrons and positrons) in materials, behaviour of liquids under agitation, thermal response of human skin or magnetic levitation, among others. As a consequence, developing data analysis methods is a common task for me.
