Structural cell biology of bacterial biofilm formation
The majority of bacteria on earth do not exist as single isolated cells but rather form macroscopic, surface-attached, multi-cellular communities known as biofilms. Bacterial biofilms play a role in many diseases and infectious processes like cystic fibrosis and urinary tract infections. Biofilms may also form on abiotic surfaces provided by clinical devices including implants and catheters. Furthermore, bacterial cells in a biofilm community are highly tolerant to antibiotic treatment. Understanding this fundamental bacterial developmental process is therefore critical to understand the colonization process of pathogenic bacteria.
The goal of the lab is to use structural biology techniques, coupled with high-resolution imaging to study general principles governing bacterial biofilm formation. We will use electron cryomicroscopy (cryo-EM) and tomography (cryo-ET) to resolve structures of molecules that mediate biofilm formation. Correlated light and electron microscopy (CLEM) coupled with mass spectrometry (MS) will be used to support our investigations. We will combine in vitro reconstitution of key molecules with in vivo imaging to understand how bacteria form biofilms.
