I employ both analytical theory and computer simulation methods to study the structural and dynamical properties of soft matter, including single-polymer chain systems, liquid crystals, Langmuir monolayers, and biomembranes.
Structural and dynamic properties of polymeric systems, such as Langmuir
monolayers, liquid crystals, and polypeptides - simulation techniques used,
include parallel-tempering, discontinuous molecular dynamics (DMD) and
transition path sampling
