Hi, I am David Scheidweiler, SNSF postdoctoral fellow at the University of Cambridge, UK. With a background in chemistry, I moved towards questions in microbial ecology, specifically how physical constraints impact microbial life in spatially complex environments.
During my PhD at EPFL, I explored how biophysical mechanisms control bacterial dispersal [J. R. Soc. Interface] and biofilm morphogenesis in complex systems [The ISME Journal] . I then moved to the EFMlab at the University of Lausanne, where we explored how the spatial complexity, typical of biological tissues, controls heterogeneous flow [Nat. Commun.] and sustains bacterial interactions [Nat. Commun.]. During a visiting period at Institut Pasteur, in the Biofilm Genetics Unit, I focused on the interactions of gut commensal in presence of food derived polysaccharides. Currently, at the University of Cambridge, in the lab of Kiran Patil, I use microfluidics to unravel how flow and resource heterogeneity modulate interactions of a complex community of gut bacteria. |
