I study and design a variety of amorphous materials, including ultrastable glasses, organic photovoltaics, and auxetic metamaterials.
Ultrastable glasses formed by a process of physical vapor deposition display kinetic stability equivalent to glasses which have been aged for many years. I use model systems to understand how the process of vapor deposition affects the underlying structure of the glass, and how this structure can be controlled
Solution-processed organic photovoltaics are a potentially low-cost alternative to traditional silicon-based solar cells. The micro-scale morphology of organic photovoltaics is one of the main factors which controls device efficiently. To achieve ideal morphologies, an improved understanding of solubility in organic photovoltaic materials is essential. I work to identify the key aspects of these structurally complex materials which control solubility in order to provide necessary insight to experimentalists.
When one compresses a material in one dimension, intuition predicts that the material’s sides will bow outwards. In most cases, this intuition is correct. I design materials where the opposite happens. When the material is compressed, the sides bow inwards. If the effect is pronounced enough, the materials becomes locally very hard where compressed. I work closely with experimentalists to validate the models I develop in simulation.
I am also the lead developer of our group’s GPU-accelerated molecular dynamics software, DASH.
