My name is Dr Rohin Francis and I am a cardiologist in the UK. I trained in London and Cambridge and I am currently undertaking a PhD at University College London.

I make YouTube videos concentrating on topics that don't get covered elsewhere like offbeat science, understanding why modern medicine doesn't always work, or forgotten chapters of history. Then I ruin it all by crowbarring in as many bad jokes as I can. Studies have shown that watching is associated with a 400% relative risk increase of becoming a more fragrant human being (actual risk increase 0.002%).

​

Please don't ask for medical advice as I cannot give any online. Nothing I say is medical advice. How do you even know I'm a doctor? I'm just an early IBM Watson prototype that went horribly wrong.
