This week, a closer look at the role journals both prestigious and predatory play in science and academia. Dr David Moher, Director of the Centre for Journalology at Canada’s Ottawa Hospital Research Institute, joins Ray to explore the way publication practices and the 'publish or perish' mentality shape researchers’ careers and the research agenda more broadly.

Professor Fran Baum is a Matthew Flinders Distinguished Professor of Public Health and the Director of the Southgate Institute of Health, Society and Equity at Flinders University in South Australia. This week, she joins Ray to shine a light on the role of the social determinants of health, and explain some of the ways we could improve the daily lives and life expectancy of people around the globe.

This week, Dr Arnav Agarwal joins Ray to share the perspective and experiences of a young, recently graduated doctor working in a busy, metropolitan hospital. Despite the long shifts and demanding environment, Arnav makes time and space to reflect on work, life and mortality through his thought-provoking poetry and volunteer work.

This week, Ray ventures into the notoriously complex field of nutrition with special guest, Professor Marion Nestle. Named by Forbes as one of the world's most powerful foodies, Marion’s stellar career spans five decades of research, teaching, advocacy work and the publication of countless prize-winning books.

After ten years at the helm of the Cochrane Library, Dr David Tovey recently stepped down as Editor-in-Chief. This week he joins Ray to reflect on Cochrane’s past, present and future and share some of the challenges and rewards of leading one of the world’s largest and most trusted health research networks.

Our latest series kicks off with Australia’s multi-award-winning health and science reporter, Liam Mannix. He joins Ray to share his insights into the role and impact of evidence, advocacy and investigative reporting in today’s ever-changing media landscape.

Not sure what The Recommended Dose is all about? These quick highlights from a few of Ray's many special guests will give you the idea...

Catch all the full-length, wide-ranging interviews on series 1 and 2 of The Recommended Dose with Ray Moynihan wherever you listen to your favourite podcasts.

Named by Reuters as one of the most influential scientific minds of our time, this week’s guest wears many hats and pursues all kinds of surprising interests. Jeremy Grimshaw has earned a global reputation for translating evidence into genuine changes that improve human health. He’s a Professor of Medicine at the University of Ottawa, President of the global Campbell Collaboration and a long-time Cochrane luminary. And as Ray discovers, he can make complex behavioural science, obscure music festivals and Formula 1 racing the most comfortable of companions in the course of just one lively conversation. Here, Jeremy closes out series 2 of the Recommended Dose with his original insights into health and social sciences research, and throws in some top musical tips for good measure.

This week a very different kind of conversation on the Recommended Dose – one that considers the art of medicine more than the science. Iona Heath is a long-time family doctor who has worked in a London GP clinic for over 30 years, and at one time became President of the Royal College of General Practitioners. With an international profile, gained in part through her much-loved writing in the BMJ, Iona is unlike many of our previous guests. For a start, she loves words more than numbers, and literature more than clinical guidelines. Host Ray Moynihan caught up with Iona at a recent conference in Helsinki – where she'd just presented little data but much food for thought from the likes of novelists EM Forster and James Baldwin. Here, she shares more of her love of literature and thoughtful commitment to the best kind of patient care.

This week Ray sits down with the man best known as the godfather of Evidence Based Medicine (or EBM), Professor Gordon Guyatt. Together they explore the past, present and future of EBM, and look at how an approach encouraging doctors to look more rigorously at the evidence grew into a global reform movement to better inform all our healthcare decisions.

Like most global movements, EBM is not without its critics. Acknowledging this, Gordon shares his thoughts on prominent critiques that argue EBM has been 'hijacked' by commercial interests. And on a more personal note, he reflects on his early dreams of being a novelist, his four tilts at election to Canada's Parliament, and the many ways his two very different parents have shaped his world view.
