Building a robust PVC species phylogeny
This project aims to decipher the evolutionary histories of PVC bacteria and investigate the evolution of their genome content underlying their unique... -
Tracking down the bacterial ancestor of mitochondria
Mitochondria are a key feature of eukaryotic cells. The bacteria-derived organelles likely played an important role in early eukaryotic evolution. In... -
An automated workflow for ortholog informed generation of gene trees
We develop an open-source, automated workflow to generate high-quality gene trees to enable non-experts to study the evolution of genes of interest... -
Wanted: Asgard archaea – Isolated and Alive
We aim to isolate live archaea using (among others) anaerobic cell sorting. -
Tracing the ins & outs of horizontal gene transfer in eukaryotic microbes
Using evolutionary analyses to investigate how horizontal gene transfer affects the biology and lifestyles of microbial eukaryotes -
Cell biology and ultrastructure of novel archaea
The microbial diversity on our planet is vast. Yet, while a considerable fraction of this diversity has been uncovered in recent years using... -
Exploration, expansion and reshaping of the tree of life
Driven by the development of powerful sequencing technologies, the existing microbial diversity on our planet is currently being genomically explored... -
Next-generation cultivation and ecophysiology of novel prokaryotes
The microbial diversity on our planet is vast. Yet, while a considerable fraction of this diversity has been uncovered in recent years using... -
Cultivating Asgards, eukaryotes’ closest relatives
Using targeted cultivation methods to cultivate novel members of the Asgard archaea.
