Thermodynamic properties of molecules and clusters
The prediction of thermodynamic properties of molecules and molecular clusters is an active research area in our group (also see "Aerosolized environmental nanoparticles" above). This line of endeavor arose from postdoctoral research under Donald Truhlar (U. Minnesota) and David Freeman (U. Rhode Island). Current work includes collaboration with Mark Tuckerman (New York U), focused on the application of machine learning techniques to molecular dynamics simulations of free energy surfaces.
