About
Engineering with an environmental focus
I recently completed MSc study in Sustainable Chemical Engineering at Newcastle University, achieving a 76% Distinction-level average across taught modules, with my dissertation result pending. I previously completed a BEng (Hons) in Chemical Engineering.
I’m particularly interested in water and environmental engineering, process engineering, sustainability and the wider energy transition.
While applying for graduate roles, I’m developing independent research articles and preparing fundraising challenges for Cancer Research UK. Alongside this, I continue to work in hospitality with supervisory responsibilities, supporting colleagues and helping coordinate service.
