Dr Xand van Tulleken

Dr Xand van Tulleken is an expert 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. It has numerous nominations and two children's BAFTA awards plus a Broadcast Award for Best Children's programme. Their Operation Ouch tours of Australia in January 2018, 2020 and 2022 were massive hits, selling out all venues including the Sydney Opera House. The Operation Ouch UK residency at The Apollo Theatre in London's West End also received rave reviews.

In 2021, the van Tullekens launched the award-winning podcast A Thorough Examination with Drs Chris and Xand. The podcast quickly reached the top of multiple charts, with the first series exploring Xand’s relationship with ultra-processed food. In the second series, released in 2022, the brothers examined whether and how people can change ingrained habits. The podcast remains a key part of their ongoing work in public health advocacy.

Since 2020, Xand has been a resident doctor on BBC One's flagship daytime show Morning Live, providing trusted medical advice to millions of viewers. He previously hosted Healthcheck UK Live, a BBC daytime show that aimed to guide the public through health challenges during the COVID-19 pandemic. His work on the pandemic was deeply personal - he and Chris explored their own experiences with the virus in the critically acclaimed BBC One documentary Surviving the Virus: My Brother & Me. He also fronted a series of Channel 4 documentaries, including Coronavirus: How to Isolate Yourself, When Will Lockdown End?, and How to Avoid a Second Wave.

Xand and Chris have continued to blend science, entertainment, and public engagement through their television work. In 2019, they hosted Twinstitute for BBC Two, testing competing health theories using pairs of identical twins.

Xand has also tackled major public health topics in solo projects. His BBC One documentary The Truth About Carbs (2018) explored the science of nutrition. He also investigated the dangers of urban pollution in the BBC One current affairs film Fighting For Air, which sparked national discussion about air quality in British cities.

In addition to his work in medicine and broadcasting, Xand has a strong background in global health. He has reported for CNN in the US, covering major health crises such as the Ebola outbreak, and has appeared on networks including Al Jazeera, MSNBC, and the BBC World Service.  He has also hosted historical documentaries for Channel 5/Paramount, covering topics such as The Smog, The Vikings, and The Plague, combining his medical expertise with a passion for history.
