Nicholas completed his Advanced Science degree in climate dynamics and physics in the University of New South Wales. In his honours year in the Climate Change Research Centre, he focused on paleoceanography and ran transient climate simulations with prognostic oxygen isotopes (UVic ESCM) to constrain the spatial origin of Meltwater Pulse-1A (14.5 ka) -- an episode during which sea levels rose by 15 metres in less than 400 years. In 2019 he began his PhD, running an Australian coupled model, ACCESS-ESM, to better understand past carbon cycles and hydroclimate in the Last Interglacial (LIG, 127 ka).
