Profile

I am a PhD candidate in the Robinson Research Institute at Te Herenga Waka—Victoria University of Wellington. My research focuses on understanding the ultrafast photophysics of organic light-emitting materials using advanced spectroscopic techniques.

In my work, I investigate excited-state processes in thermally activated delayed fluorescence (TADF) materials and related organic systems. By using ultrafast transient absorption and transient grating photoluminescence spectroscopy, I aim to uncover the fundamental mechanisms governing energy transfer and charge transfer on femtosecond to nanosecond timescales. These insights contribute to the development of more efficient next-generation optoelectronic devices such as organic light-emitting diodes (OLEDs).

I enjoy combining experimental techniques with physical insight to answer fundamental questions about light–matter interactions, and I value being part of a collaborative research environment.
