How wonderful to see so many familiar faces and names cropping up on this platform. 😃 Welcome to new followers too. 👋

If you don't know me yet, hello! I'm about #SciComm #Events #Fireworks #HealthAndSafety #LGBTQ+ and #PPIE (lived-experience and patient advocacy) and a few other bits.
Matthew is facing the camera, showing a mouth-open exicted expression and wearing safety glasses. He is pointing at his left hand which is inside a bright white firework fountain as it burns. Sparks are bouncing off his hand. This is a controlled stunt and should not be attempted without training and appropriate control measures in place.

I have just missed my face and poured water all down myself whilst trying to take a tablet.

People put me in charge of explosives, you know.

🔥 What a weekend at the Festival of Fireworks, Catton Hall! Thousands gathered under the night sky for a spectacle of colour, sound and shared awe — and I had the privilege of being host. 🎤 Nights like these remind me why live events matter.

A dark sky filled with spectacular golden brocade (glitter) shell bursts, over the top of 11 pink and gold mines erupting from the ground, with 22 45-degree gold-glitter comet punctuations. A photo of my announcer's script, showing the start of my 4pm announcement. The control point, with four individual firing systems (all FireOne in this photo). They are set up on trestle tables, with laptop screens visible and the lids of the hard-plastic cases of the control panels open. Some of the crews can be seen in the background chatting in small groups.

The absolute winner of the day: Seeing lab-grown human heart cells beating together in a dish...absolutely mind-blowing! I saw the very cells that drive every heartbeat, all contracting in unison. 🫀 Even with my science background, this felt magical and deeply moving. #CureHeart #research

Earlier this week, I was fortunate to be part of a #Cardiomyopathy UK visit to #CureHeart Labs @ox.ac.uk . We went behind the scenes to see cutting-edge work on inherited heart conditions. Lots of uplifting conversations between researchers and patients giving real hope for progress.👇

I've been having a break from social media lately to preserve my mental wellbeing, but today I really need to say this:

However you identify; M, F, MTF, FTM, non-binary, gender-fluid or neutral, YOU ARE VALID. 🏳️‍⚧️

#Trans friends enrich my world. I can't imagine it without you. xx

This morning's partial #SolarEclipse, evidenced by my solar panels. 😎 Cool, eh?

For the first time ever, I'm actually able to attend an @equitybwm.bsky.social meeting. We've had some amazing speakers today and now we are onto serious union business. Very glad to be part of this. Together we are Stronger.

Bring extra sparkle to your festival with a science and maths infused fire and art mashup.
Drop me a line if you are interested. I adapt the size and scale of the shows for each venue.

Matthew is on stage in a large Victorian City Hall venue, with a high arched ceiling and theatrical lighting overhead. In the foreground is the audience who are watching the show. A six-metre high wall of pyrotechnic gold and silver sparks is erupting at the front of the stage with dramatic effect.

A stonking finish to British Science Week at the weekend, with headline shows at #ColliderFest.

I left a little decorative post-show souvenir at City Hall. 😄 #Hull #BSW25

Lovely to join the friendly @benendenbells.bsky.social ringers this evening, although it did require a lot of knots in my rope. Me and my high heels... 😆 #bellringing

Mid #BSW25 school shows. I was very tempted to shave my head, paint myself blue and hit the table with fluorescent sticks.
A very blue, darkly-lit stage containing a table and some black wooden boxes. The photo is so blue that it is almost not worth posting.

Tosh downtime this afternoon is taking me back to my degree year abroad, when I first discovered Moroccan cuisine.

I suddenly have an urge to fire something in celebration, however my shows aren't until next week.

MUST RESIST.

18 months on, and this still feels surreal, even for a clued-up #scicomm pro!

A clinic in another part of the country can access the implant INSIDE my body to check that I am safe. 🤯

Flippin' marvellous! 🫀😀

This time of year = Site visits and consultancy. Bit soggy under foot, but lovely sunny spells are a bonus. 🙂

It's actually a great comfort knowing that it is there, keeping an eye on me. It's saved my life once already. 🫀👌😃 #heart #cardiomyopathy #ARVC #AVC

I have a little drummer tapping away under my ribs at a perfect 50 bpm. 🥁

Typical investigative physicist... I keep tweaking my posture to see which positions allow me to feel it.

I should probably get out more. #cardiomyopathy #AVC #ARVC

Site visit today = Site boots dilemma.

Clean footwear makes a good first impression.

Dirty boots look like I've actually done site work before.

I think I'll just dust off the sheep poo and leave the mud in situ.

When I am big and grown up, I want to go to conferences and communicate through the medium of purple modelling clay, rainbow lollipop sticks and sparkly pipe cleaners. 🙏😀✨🌈🦄 #SciComm

Routine #HIV testing in emergency departments has led to more than 1000 new diagnoses
and it's helping to stop new transmissions in #England.

Opt-out testing saves money, removes stigma, and finds people who would otherwise not receive a test.

Back from a much-needed holiday. This is my favourite photo from the week.

Any guesses as to where this was taken? 🤔
No peeking here for clues! You are looking at the underside of a civil engineering structure. It features triangulated girders and a cantilever deck running along the left and right sides. The blue sky has a few white clouds visible.
