We conduct research at the cutting edge of the intersection of nanomechanics, mesoscale physics, and chemistry in close collaboration between theory and experiments. We are interested in simulating solid-state-biomolecular hybrid devices employing strain and field effects in atomically thin membranes to achieve new-generation high-accuracy biomolecule sensors. The potential applications include DNA and protein sequencing. As part of a separate research direction, we are also interested in simulating friction at the nanoscale, including structural and thermodynamic properties of friction in atomically thin layers and lamellar materials.
We utilize a set of rigorous top-down methods, ranging from analytical theory calculations to large-scale atomistic (large-scale molecular dynamics) and density functional theory calculations. Our special focus is on charge transport and interfacial phenomena.
