General interest and educational (suitable for the general public and secondary schools):

  • Herding Hemingway’s Cats – With the help of cats with thumbs, fish with hips and wobbly worms, Kat unpacks the mysteries in our DNA and explains the latest thinking about how our genes work.
  • Who do your genes think you are? – Genetic tests are cheap and widely available, enabling anyone to delve into their health and ancestry, from discovering hereditary cancer risks to unearthing Viking heritage. There are even genetic tests for fitness programmes, skin care and wine recommendations. This talk explores the science behind genetic testing, and separates the facts from the hype.
  • Nature, nurture and the wobble: why everything you know about genetics is wrong – The history of genetics starts with Mendel and his pea plants. His work led to the idea that one gene is linked to one trait, and one gene fault causes one disease. But the recent revolution in DNA sequencing is revealing that it’s much more complicated. From strange patterns of inheritance to real life genetic superheroes living amongst us, whose DNA provides them with resilience against serious illnesses, Kat explains what we do and don’t know about how our genes work. [Alternative title: How to be a superhero]
  • Did the Victorians Ruin the World? – Based on the critically acclaimed Radio 4 series, this one-woman version is a romp through the best – and worst – of Victorian inventions, from flushing toilets to luxurious beards.
  • Pimp My Genome – Epigenetics is the latest biology buzzword, but what exactly does it mean? And can you really alter your genes with diet, stress or even positive thinking?
  • Cut, Paste, Clone – In the past few years we’ve seen exciting headlines about new genetic engineering techniques such as CRISPR, allowing scientists to alter genes with pinpoint precision. This talk explores how these technologies work, how they might be applied, and whether we really will see designer babies any time soon.
