frances a. houle
Deputy Director for Science and Research Integration and Principal Investigator
Dr. Houle’s research interests include: chemical modification of nanoparticle, semiconductor, metal and polymer interfaces, surfaces and films; oxidative ageing of atmospheric aerosols; nanoscale pattern formation; development of novel experimental methods for characterization of nanoparticle, thin-film, surface and interface physics and chemistry, including nanoscale composition, reaction mechanisms, and nanomechanical properties; stochastic simulation methods for complex chemical reactions including transport, with special interest in the condensed phase; and scenario development for prospective lifecycle assessments for new energy technologies.
Within JCAP, Dr. Houle uses stochastic chemical kinetics simulation methods to characterize mesoscale transport processes studied in novel membrane architectures that can transport ions but block gases and organic CO2-reduction processes. The simulations are used to interpret time-dependent measurements of membrane properties, with spatial and temporal resolution spanning nanometers and nanoseconds to real film thicknesses and relaxation on the timescale of minutes to hours. By capturing uptake, swelling and deswelling, release, and non-Fickian effects, the models provide a detailed and realistic means of connecting membrane properties to the movement of neutral and charged species through them.
