Tiago Costa obtained his PhD in Molecular Biology from University of Umeå, Sweden in 2012 where he studied, the molecular and biochemical details of Yersinia Type III Secretion System (T3SS) translocators in the lab of Prof. Matthew Francis.
As a postdoctoral researcher in the laboratory of Prof. Gabriel Waksman (ISMB, London, UK) he studied the structural and molecular details of the E.coli conjugative Type IV Secretion System (T4SS) by cryo-electron microscopy (Cryo-EM) (Costa et al, Nat Rev Micro, 2015). He recently solved the structure of the bacterial F-pilus at near-atomic resolution by Cryo-EM, which provides the first atomic view of a bacterial extracellular appendage made of a protein-lipid complex. This study set the stage for understanding how DNA is transported from one bacterial cell (donor) to another (recipient), a process that leads to the spread of antibiotics resistance genes (Costa et al, Cell, 2016).
Tiago Costa joined the Department of Life Sciences at Imperial College, London, UK in 2017 as a Lecturer in Bacterial Pathogenesis to study by Cryo-EM, the role of T4SSs in the pathogenicity of intracellular pathogens. To fully understand how these macromolecular machines work, he uses a multi-disciplinary approach that includes: bacterial genetics (gene disruption and site-specific mutagenesis), membrane proteins biochemistry, cutting-edge single particle Cryo-EM, X-ray crystallography and protein cross-linking coupled with mass spectrometry (XL-MS).
