University Professor in the UK teaching stats to undergraduates and postgraduates for 15 years.

Lewis is an astute quantitative biologist with a deeper understanding of statistics than most bioscientists, having made seminal contributions to the field. I teach on the same programmes as Lewis and have found listening in on his statistics lectures to undergraduates a joy; they are lucid, elegant, and use real-world examples for invaluable practice. I've learnt a thing or two from him myself and enjoy his sometimes irreverent, contrarian sense of humour.

As a long-time colleague of Lewis, I know he is excellent at distilling the tricky world of statistics into concepts that every student can understand. He’s been lecturing and tutoring stats, at university and online, for many years, and it shows! He’ll work with you at your pace, and is more than happy to go over ideas lots of times if that’s what you need. A session of more with Lewis will seriously boost your stats abilities.
