"I guess it is a bit like a dream come true, it's just all happened so quickly."
Mr Trewin, a former John Paul College student, said while he was excited about the journey ahead he couldn't help but be a bit nervous about his trip. "There's a lot of expectation and it's going to be a bit of a change, moving from little old New Zealand."
As for the future, Mr Trewin hoped the scholarship would help him land his dream job doing strength and conditioning work with players in the English Premier League or, better yet, with his favourite team, Arsenal.
Mr Trewin, who described himself as "football mad", said undertaking a PhD in sport made sense. "I guess it'll help me get that little bit further and it looks good on my CV, and I just love sport."
He'll be writing a blog, My PhD Journey, at www.jtsphdjourney.
