Electron cryomicroscopy (cryo-EM) and tomography of bacterial biofilms

Our laboratory uses electron cryomicroscopy (cryo-EM), tomography (cryo-ET) along with associated image processing techniques to study biofilm formation of pathogenic bacteria like Pseudomonas aeruginosa and Escherichia coli. Correlated light and electron microscopy (CLEM) coupled with mass spectrometry (MS) are used to support our investigations. We combine in vitro reconstitution of key molecules with in vivo imaging to understand how bacteria form biofilms. Please contact Tanmay Bharat if you are interested in our work or visit our page on the Dunn School website for more details.
