My research interests are in developing computational methods and tools for applications in molecular simulations nonlinear dynamics and signal processing.
Molecular simulation: Structural and dynamic properties of solid-liquid interfaces; calculating free energy of solid-liquid interfaces; estimating thermodynamic errors of numerical integrators for molecular dynamics. Nonlinear dynamics: Methods for locating unstable periodic orbits in chaotic dynamical systems; symbolic dynamics generating partitions and homoclinic tangencies in non-hyperbolic chaotic systems; transition to chaos with multiple positive Lyapunov exponents (sometimes called ""hyper-chaos""); chaotic transitions in semiconductor lasers subject to delayed optical feedback.
Measurements and data processing: Analog representation of a measurement process;
Implementation of nonlinear filters for continuous measurement processes.
