I am interested in deciphering the genetic basis of adaptation and phenotypic plasticity of flowering time of plants, especially in response to changing environmental conditions. I use natural variation as a resource of genetic diversity to identify new alleles of known genes to better understand gene function, regulation, and interaction. Employing CRISPR/Cas9 technology, I investigate GxG interaction by testing a deleterious genetic deletion in a large set of natural Arabidopsis genetic backgrounds. I also work on herbicide resistance of Alopecurus myosuroides (black-grass), a plant species classified as a weed. Several next generation sequencing technologies and methods are applied to study the dynamics of resistance dispersion and the population structure of local and nationwide samples.
