I joined the Thompson lab in early 2012 and am currently working on a comparative genomics study using 40 different D. discoideum strains, which exhibit markedly different ‘traits’ during growth and development. The comparison of the genomic sequence of all genes will elucidate how many and which genes are connected to these traits.
Apart from this, I am also working on various transcriptome studies, which entail comparisons of knock-out mutants to wild type as well as differences between stages in development and cell types also focussing on potential antisense regulation of specific genes.
From 2010 to 2012 I worked in Professor Peter Lockhart’s lab in Palmerston North, New Zealand. There I was involved in the assembly and analysis of EST libraries of two species from the allopolyploid plant genus Pachycladon, which is endemic to New Zealand and parts of Australia. Using different sequencing methods, these EST libraries then enabled us to find differential expression of genes important for adaptation to e.g. growth in different altitudes. Part of this work resulted in the important observation that hybridisation increases the adaptive potential of species and can therefore be crucial to their adaptation to climate change.
Between 2006 and 2010 I was a PhD student in Professor William Martin‘s lab in Duesseldorf, Germany. My thesis was entitled ‘Clusteranalysis and phylogenomics of eukaryotic genes of prokaryotic origin‘ and focussed on determining the most likely ancestor of primary and secondary plastids using all protein sequences of 710 fully sequenced eukaryotes and bacteria.
