The engineering industry, like many other STEM sectors, has a problem with diversity: one that Dawn Bonfield believes we can and must fix, if we're to get a handle on much more pressing planetary problems...Dawn is a materials engineer by background, who held roles at Citroën in France and British Aerospace in the UK. But, after having her third child, she made the difficult decision to leave the industry - as she thought at the time, for good. However a short spell working in post-natal services and childcare gave her new skills and a fresh perspective. This led to Dawn rehabilitating the struggling Women in Engineering Society and creating ‘International Women In Engineering Day’, which has just celebrated its 10th anniversary.Today, she’s Professor of Practice in Engineering for Sustainable Development at King’s College London, and the founder of Magnificent Women: a social enterprise celebrating the story of female engineers over the past century. She’s also President of the Commonwealth Engineers’ Council and has had her work supporting diversity and inclusion recognised with an MBE.Dawn talks to Professor Jim Al-Khalili about why 'inclusive engineering' should not be dismissed as tokenism, and why she's optimistic about the engineering sector's power to change the world.

In recent decades, we have taken huge steps forward in treating formerly fatal viruses - with pharmacological breakthroughs revolutionising treatment for conditions such as HIV, hepatitis and herpes. Raymond Schinazi has played a big role in that revolution.Ray was born in Egypt, where his mother’s brush with a potentially deadly illness during his childhood inspired a fascination with medicine. His childhood was scattered; after his family were forced to leave their homeland and travelled to Italy as refugees, Ray ended up on a scholarship to a British boarding school - and subsequently went on to study and flourish in the world of chemistry and biology.Today, Ray is the director of the Laboratory of Biochemical Pharmacology at Emory University in Atlanta, where he also set up the renowned Center for AIDS Research. His work in the early days of HIV studies led to drugs that many with the virus still take today; while his contribution to developing a cure for Hepatitis C has saved millions of lives around the world.Speaking to Jim al-Khalili, Ray reflects on his route to success and explains why he is confident that more big breakthroughs are on the horizon.

From anorexia nervosa to binge-eating, eating disorders are potentially fatal conditions that are traditionally very difficult to diagnose and treat - not least because those affected often don’t recognise that there’s anything wrong. But also because of the diverse factors that can influence and encourage them.Janet Treasure is a Professor of Psychiatry at King’s College, London - where she's focused on understanding the drivers behind these disorders, to help develop more effective treatments. Her study of twins in the 1980s offered one of the earliest arguments of a genetic link to anorexia, rather than the purely psychological motivations accepted at the time; while her most recent work explores holistic ways to better treat these conditions.Speaking to Jim Al-Khalili, Janet explains the work that's revealed anorexia's roots in both body and mind - as well as how attitudes towards eating disorders are slowly changing.

Marfan syndrome is a genetic disorder that makes renders the body’s connective tissues incredibly fragile; this can weaken the heart, leading to potentially fatal aneurysms. What’s more, anyone with the condition has a 50/50 chance of passing it on to their children.Dr Anne Child is a clinical geneticist who’s dedicated her professional life to finding answers and solutions for people affected by Marfan’s.Born in Canada, she met her British future-husband while working in Montreal in a case she describes as "love at first sight" - and in the 1970s she relocated her life to the UK.There, an encounter with a Marfan patient she was unable to help set Anne on a career path for life. She subsequently established the team that discovered the gene responsible for Marfan's, and founded the Marfan Trust to drive further research. Since then, life expectancy for those with the condition has jumped from 32 years old, to over 70.Speaking to Professor Jim Al-Khalili, Anne shares how she and her team achieved this remarkable turnaround.
