Welcome to the Kaessmann lab



The molecular and cellular origins and evolution of vertebrate organs

Our lab has been interested in a range of topics related to the origins and evolution of organs in mammals and other vertebrates as well as the various underlying genomic/molecular changes. In the framework of our research, we have generated and analyzed comprehensive genomics (e.g., RNA-seq) datasets based on samples from our large organ collections. We have thus illuminated the origins and functional evolution of protein-coding genes, alternative splicing, long noncoding RNAs, microRNAs, and sex chromosomes across organs and species, as well as associated phenotypic implications. More recently, we have begun to bring the work of our lab to the level of individual cells using state-of-the-art single-cell genomics technologies and bioinformatics procedures. In a major set of new projects, we seek to scrutinize the origins and evolution of the vertebrate brain and its constituent tissues and cell types based on samples from representatives of all major vertebrate lineages, ranging from jawless vertebrates (e.g., the sea lamprey) to mammals (e.g., platypus and human). In other current projects, we investigate the evolution and development of gonads, liver and intestine (dietary adaptations), and the placenta across representative mammals.
