Ian’s talks have been described as ‘highly engaging and informative’ ‘One of the best speakers we’ve ever had’. Ian is the retired Headmaster of a large comprehensive school and now gives highly illustrated talks which have been extremely well received . He has degrees from several universities. He has developed a number of highly illustrated talks with a biological/medical theme. Titles include: The discovery of Insulin and the conquest of diabetes The man who caught a million criminals - Alec Jefferys and the invention of DNA fingerprinting. How cells work - the amazing molecular machines inside our body. The history of vaccines - Edward Jenner to the Covid mRNA vaccines. The rise of the superbugs- antibiotic resistance. The history of genetics - the race to the double helix’. I have given 50 of these talks to Rotary Clubs, Probus Clubs, U3A groups and other societies with uniformly excellent feedback. Talks can be anything between 30 and 60 minutes, according to your preference.
