Description

Nanoscience and Quantum Engineering

Experimental and theoretical approaches to complex problems at the interface of non-equilibrium quantum statistical mechanics with dynamical systems, estimation and control: real-time quantum feedback control, quantum information science, nanophotonic circuit theory, quantum nonlinear dynamics in single-atom cavity QED; quantum probability; control-theoretic methods in non-equilibrium quantum statistical mechanics.

Biophysics

Experimental and theoretical approaches to complex problems at the interface of non-equilibrium statistical mechanics with dynamical systems, estimation and control: chromatin mechanics and DNA/RNA folding studied by single-molecule fluorescence diffusometry, tracking-FCS and tracking-FRET; applications of modern statistical methods and signal processing techniques in learning from single-molecule data.

Lasers and Accelerators
