Our research focuses on the optical and electronic properties of emerging semiconductors for low-cost, transformative electronic applications, including photovoltaics for energy, LEDs for lighting and X-ray detectors for medical imaging.

We use optical spectroscopy to understand material and device photophysics across a range of length and time scales, linking these characteristics directly to chemical, structural and morphological properties through multimodal measurements.

This approach enables us to discover new semiconducting materials, uncover power loss mechanisms in devices, guide innovative device design and push performance towards practical limits. Our devices and operando imaging methods are applicable across fields including energy materials, medical imaging and biological systems.
