Pint of A Pint of Science mini-series. Episode 1: Coding cells with Dr Mark Kotter

April 7, 2021

Welcome to the first episode of a very exciting three-part mini series of the Pint of Science podcast, in collaboration with, the cell coding company.

The series kicks off with Dr Mark Kotter, founder and CEO of Mark is an academic neurosurgeon and scientist at the University of Cambridge, or more accurately these days, a bio engineer. His research specialises in quite literally reprogramming cells and coding them to perform certain activities, by activating certain combinations of genes to switch them from one identity to another.

Mark and the team are working to harness the power of stem cells and turn them into medicines by looking at biology in a different way – treating cells like a piece of software. They have developed a unique control system called opti-ox™, that allows them to jumpstart the potential 'programs' within a cell which tell it how to behave (and what kind of cell to be) very effectively.

Traditionally this has been a slow and small-scale process, but's technology allows the production of these cells in quantities large enough that it could revolutionise medical treatments for everything from cancer to spinal and brain injuries.

The Pint of Science podcast is a part of the Pint of Science Festival, the world's largest science communication festival. Thousands of guests and speakers descend on pubs in hundreds of cities worldwide to introduce science in a fun, engaging, and usually pint-fuelled way.

This year, Pint of Science is going live online! We will be going digital from the 17th-20th May in the UK with a great selection and variety of online Pint of Science events.

If you're listening from elsewhere in the world, go to for more information on what's happening in your country.

You can donate and help Pint of Science through these incredibly challenging times. For obvious public health reasons, we are recording remotely at the moment - but we hope to be back in the pub very soon (and very safely).
