This research examines whether emotional sensitivity in women varies across the menstrual cycle by studying the interaction of sleep, hormones, and time. By tracking emotional memory at multiple cycle stages, the work aims to replace stereotypes with evidence and address long-standing gaps in women’s health and cognitive research.

This research explores how gut bacteria communicate with the brain to regulate appetite. Using zebrafish, it shows that dietary fiber supports microbiome diversity, producing signals that suppress hunger. Disrupted gut–brain communication from low-fiber diets may drive overeating, highlighting new targets for obesity prevention.

Feathers and blood preserve detailed biological records of Tītī stress, diet, and environment across both New Zealand and the North Pacific. By analysing hormones and stable isotopes in modern and historical samples, this research reveals how climate change affects Tītī populations and identifies which groups are most vulnerable, guiding future conservation efforts.
