It was during my time at secondary school that I abandoned religion.

Ever since Sir Isaac Newton's times, scientists have worked in the same sort of way: They show a great respect for experiment and observation, They don't cherry pick data, They take a skeptical approach to what they do. And then scientists work together to get a consensus as to what should be believed And that generates very reliable knowledge and that reliable knowledge drives innovation

At age 11 in 1960, I moved to an academic state secondary school, Harrow County Grammar School for Boys.

My main efforts focussed on trying to identify the rate controlling steps during the cell cycle. Crucial for this analysis were wee mutants that were advanced prematurely through the cell cycle and so divided at a reduced cell size.

After an extensive interview he arranged for my weaknesses in foreign languages to be over-looked and so I started a Biology degree at Birmingham in 1967.

This time at Birmingham turned me into a general biologist, and ever since then I have always tried to take a biological approach to any research project that I have undertaken.
