Dr. Seviour helped build SCELSE’s biofilm biophysics program on addressing fundamental questions in biofilm biology through the molecular basis of EPS. His discoveries of G-quadruplexes and eRNA as structural features of Pseudomonas biofilms drew attention to higher order extracellular nucleic acid structures in biofilm viscoelasticity and emergent properties. He subsequently joined Aarhus University and established the Biofilm Engineering and Sustainable Technologies Lab for delivering sustainable technologies to valorize and improve control of biofilms through an understanding of the matrix. Dr. Seviour firmly believes that the matrix is a key biological frontier, and that tackling it will create many biotechnological opportunities.
