I have studied molecular and evolutionary biology at Charles University in Prague (2005-2013). My research topic were bacterial colonies. I started with study of inter-colony signaling [1], followed by interactions of different bacterial species [2], heredity and variation in colony shape [3], volatile antibiotic inactivation system [4] and volatile compound based identification of different strains [5].

After joining KGFLD (2014 -), I continue with bacterial colony model only in-silico in the form of population simulations [6,7]. I have collaborated on simulation studies of forest tree breeding strategies [8,9] and I am currently working on simulation studies of the variation of the quantitative trait after the colonization of the new territory and the changes of adaptability to climate change. I also participate in the evaluation of genetic data for population genetics/evolutionary biology studies [10].

Another area of my interest is the evaluation of rich physiological data, such as gene expression [11], volatile metabolites [12], spectral reflectance [13] or photosynthesis parameters viewed through chlorophyll fluorescence [14,15]. For the latter two, my goal is to capture genetic variability in certain sections of the reflectance and fluorescence curves, which will lead to a deeper understanding of the significance of such phenotypes.
