Research interests: Evolutionary biology, ecology and molecular genetics

Current topics:

  • Sex-Asex: Mendelian inheritance of obligate parthenogenesis and phenotypic effects of the underlying allele (Brachionus calyciflorus)

  • Genome size evolution (Brachionus plicatilis)

Former topics:

  • (MPF1- and) MPF2-like MADS-box genes, their cis-regulatory regions and the evolution of the Inflated Calyx Syndrome (Solanaceae)

  • Host-parasite interactions (Caenorhabditis elegans, Bacillus thuringiensis)

Methods: Animal experiments, barcoding, genotyping (AFLP, microsatellites), 5’ and 3’RACE, RAGE (genome walking), semiquantitative RT-PCR, Southern Blot, transformation of bacteria and plants, phylogenies
