I am available as a media contact on topics including satellite constellations and their impact on astronomy; Wikipedia; and radio astronomy and cosmic microwave background observations. I am a postdoctoral researcher at Imperial College London; co-lead of SatHub at the IAU Centre for the Protection of the Dark and Quiet Sky (IAU CPS); and I’ve been editing Wikipedia since 2005. Below are examples of my past media engagements. I welcome media enquiries – please contact me.
Satellite constellations and astronomy
I research the impact of satellite constellations on optical, radio, and submm astronomy.
- BBC Radio Lancashire – chat about space debris and satellite constellations (around 16:30h), 24 April 2026
- Expert reaction to reports that debris from a Chinese rocket is coming to Earth (30 January 2026) – I provided an expert comment to the Science Media Centre, which was subsequently picked up by:
- Sun, SPLASH LANDING Out-of-control Chinese rocket crashes into ocean after Britain prepped ‘emergency alert’ over falling debris
- Manchester Evening News, UK in path of ‘uncontrolled re-entry’ of Chinese rocket debris falling to Earth
- Kursiv Uzbekistan, Chinese Rocket Splashes Down in South Pacific after UK Emergency Preparations
- LadBible, Out-of-control Chinese rocket smashes into Earth after UK was put on red-alert
- GB News, Britain prepares emergency alert before out-of-control Chinese rocket smashes down to Earth

- Quoted in Swarms of satellites are harming astronomy. Here’s how researchers are fighting back, Nature, 18 March 2025, on IAU CPS work to understand satellite constellations, their positions and brightness, to mitigate their impact on astronomy. Also published as In a Sky Full of Satellites, Astronomers Find Creative Ways to Observe the Stars, Scientific American, 28 March 2025, and in Light Pollution Threatens World’s Most Powerful Telescopes, Geeks Ultd, 19 March 2025.

- I co-authored a Nature paper on the optical brightness of BlueWalker 3 in October 2023. IAU CPS put out an announcement that was accompanied by various press releases, including one from my employer, Imperial College London, that quoted me. The story was covered in various publications, including:
- Wired – “Amazon Is Going to Fill the Sky With Satellites. Astronomers Aren’t Happy”
- Telegraph – “Satellites brighter than stars ‘could change our night skies forever’”
- Hot Hardware – “Astronomers Slam Massive BlueWalker 3 Satellite For Being Obnoxiously Bright”

Wikipedia
I have been quoted and have written about Wikipedia in the context of science, AI, and governance, drawing on my experience as a long-term Wikimedia contributor.

Radio astronomy
I am a radio astronomer with a specialism in Cosmic Microwave Background experiments, including Simons Observatory, GroundBIRD, and the Planck satellite. Some media coverage on this topic includes:
