Archaea are ubiquitous microorganisms that are the ancestors of all eukaryotic life and inhabit diverse environments ranging from the most extreme to the human body. Archaea that are part of the human microbiome are increasingly recognised as key health factors in metabolic conditions such as obesity. Moreover, protein complexes derived from extremophilic archaea are ultra-stable and highly resilient to extreme conditions such as heat, pH and salt and are thus of great interest for bio- and nanotechnology. My lab employs state-of-the-art single particle electron cryo-microscopy and cryo-tomography to investigate the structure and function of archaeal surface proteins. These include S-layers, which form highly stable cage-like proteinaceous cell walls and the archaellum, a filamentous molecular machine used for rotary propulsion, surface adherence, biofilm formation and cell-cell communication. Our work will provide detailed information about how archaea move through and interact with their (microbiomal) environment and inform new approaches to exploit s-layers and the archaellum machinery in nanotechnology and drug delivery.

In the news:



Our brand-new lab is home to cultivation equipment for thermophiles, a cryoEM sample preparation facility, a cryo-capable 120 kV FEI T12 electron microscope for sample screening and a cutting-edge GPU computer cluster for image processing. For high resolution imaging, we share a 200 kV Talos Arctica electron microscope with the University of Bristol.
