Barney Lewis’s Viva celebration was a lively and cheerful gathering, complete with cakes, tea, and a few beers and glasses of champagne to mark the occasion. Professor Ivan Scheblykin, the external examiner, joined the group in person and enjoyed mingling with everyone. After a short online speech from Professor Sam Stranks, gifts were presented and warm congratulations were shared all around. Later in the day, the celebrations continued as the group met at the Cambridge Blue, where more colleagues joined in — including Barney’s daily supervisor, Simon Kahmann — to toast his success well into the evening.
