My research interests are broadly in the area of polymers and soft materials for energy, water, and sustainability. In particular, I aim to develop new insights into molecular interactions and molecular assembly to bridge connections between chemical structure and performance. I use a range of synchrotron techniques, for example, energy-resolved resonant X-ray scattering and spectroscopy coupled with simulations, complementary characterization, and device-relevant measurements.
