About
Greg is an award-winning TV & Radio Science Presenter & Producer,
popular Keynote Speaker, experienced Events Host, long-time YouTuber,
and... hybrid athlete?!
If you're looking for him he'll likely be investigating the bold marketing claims
of a trending 'wonder product' for his popular BBC Radio 4 show & podcast
"Sliced Bread", or sharing consumer tips about those on BBC Morning Live.
If not, then he may be off on another science expedition to join researchers somewhere exciting in the world (he recently returned the Amazon Rainforest), or - most likely - he'll be competing in a hybrid fitness race (he's got the HYROX World Championships in the next few weeks!)
Greg has been making science content on TV, Radio, YouTube, Podcast,
& Stage for close to 20 years (gulp!):
> from investigative documentaries on TV, Radio & Podcasts,
> to ambitious interactive live shows for families on YouTube,
> to eye-catching experiments on live TV,
> and engaging keynotes & spectacular science shows
A scientist by training (first class degree in Natural Sciences from
Cambridge University), Greg regularly provides Science Communication
training and hosts multiple awards & STEM conferences. He is also
the Creative Director of digital-first production studio sciencemedia.studio
and an Emeritus Public Engagement Fellow for The Wellcome Trust.

It's what he spends most of his weekends doing! [Photo is from the Conquer Level 7 event that Greg & Big Ed won last year] |  Half Marathons - PB 1:25A lot of Greg's childhood was spent running all over the fells of the Lake District and beyond orienteering.
