As an undergraduate he worked in research groups at Oxford, Cambridge and Harvard, co-authoring papers in the Journal of Organic Chemistry and Nature. Educated first at a local state comprehensive, he won an Ogden Trust Physical Sciences Scholarship to Portsmouth Grammar School, where he achieved five A*s at A-level, placing him in the top 0.1% nationally.
William worked as a Consultant at the World Health Organization on the Global Polio Eradication Initiative and as a Management Consultant at Dalberg Global Development Advisors, before beginning a PhD at Imperial College London in mathematical modelling of infectious diseases. He has tutored maths and the sciences for many years, given talks at more than ten comprehensive schools on applying to Russell Group universities and Oxbridge, and run practice interviews for Natural Sciences and Chemistry applicants.
William first focuses on the areas a student finds most difficult, prioritising topics coming up soon in exams. Past papers play a central role, giving the most relevant practice and a clear record of progress, and he sets and marks work between sessions.
