UCL Health of the Public


Meet our hosts!

Dr Xand Van Tulleken

Xand Van Tulliken
Dr Xand van Tulleken’s main interests and expertise lie in Public Health, Medicine, Humanitarian Aid and Anthropology and is one of the BBC’s leading science presenters having worked on many flagship Health & Science programmes.

Alongside his twin brother Chris, Xand presents CBBC’s Operation Ouch! The series has been a huge global success, involving self-experimentation and lab work to find weird and wonderful ways of showing kids what goes on in hospitals, and inside our bodies. During 2020, Xand hosted Morning Live and Healthcheck UK Live on BBC One, as well as exploring the very personal side of COVID-19 alongside Chris, in the BBC One documentary Surviving the Virus: My Brother & Me.

Last year saw Xand publish three new books – How to Lose Weight Well, to accompany the hit Channel 4 series; Operation Ouch! The HuManual - a book all about human biology for children; and Secrets of the Human Body which tied in with his and Chris’ ground-breaking BBC2 Science series.
