consequences of asexual reproduction in the genomic era

Monty Phyton's Sex Education Sketch

My interest is to combine the fields of evolution, ecology and genetics to understand genomic consequences of asexual reproduction.
My current work focuses on signatures of ancient asexuality in oribatid mite genomes and transcriptomes. Especially, I am looking into the fate of transposable elements (TEs) in sexual and putatively long-term asexual lineages. Further, I am interested in how TEs may play a role in speciation events. Also, investigations of spermatogenesis, deleterious mutation accumulations and comparative studies of mitochondrial genomes of mites are in progress. These projects incorporate next generation sequencing technologies and bioinformatic analyses into evolutionary investigations.
