Research

We use multiscale simulations to probe the mechanisms and driving forces behind biomolecular processes such as electrochemical charge transport, protein-membrane targeting, lasso peptide folding and bacterial methane oxidation. We are motivated to enable climate, medical, and societal solutions by advancing fundamental knowledge and insight.
