The hardest performance environment there is. Tess prepares the people who leave the planet — and studies what happens to them when they do.
A PhD from the Centre of Human & Aerospace Physiological Sciences at King's College London, investigating hyper-buoyancy flotation — a ground-based analogue of spaceflight — and its effects on sleep and cognitive function. As a visiting scientist at NASA Ames Research Center she worked with GeneLab, exploring what spaceflight does to the human body at the molecular level.
Founder of Astro Perform, the human spaceflight experts: preparation platforms, simulated applications and 1:1 coaching for astronaut candidates, and consultancy for space agencies designing and running selection campaigns. Because astronaut selection is more than an application — it's a journey.
Named an Emerging Space Leader in 2019 by an international panel, with scholarships from the UK and European space agencies and research awards from the International Astronautical Federation, the Aerospace Medical Association and NASA's Human Research Program.

A regular voice on human spaceflight in broadcast and at conferences — from BBC Breakfast to industry keynotes — and a guest on podcasts including Supporting Champions and The Convex Conversation.
A master scuba diver — because the closest thing on Earth to weightlessness is the deep. Neutral buoyancy is how astronauts rehearse spacewalks, and it rewards the same qualities as spaceflight: preparation, buddy trust and total presence.
