The epidemiology of space with Sabine Bellstedt

Release Date: 22 April, 2025

A lot about what it is to be human is understanding who we are and where we came from, whether that's genetically, geographically, or otherwise. But what if we zoomed out and approached it at a galaxy level? What could we learn about who we are, what we understand about the universe, and what humans are capable of achieving?

Sabine Bellstedt is an astronomer working on the epidemiology of space and on large scale projects with international teams not only to understand the universe, but how we understand the universe. Join us as we speak with Sabine about her journey to astrophysics, space epidemiology, and the impact of astronomical innovation.

About Sabine Bellstedt

Sabine Bellstedt is an astronomer who works with enormous galaxy surveys. These are large international projects that collect data for millions of galaxies, with the goal of piecing together the evolution of galaxies and the Universe more broadly across almost 14 billion years of cosmic time. Sabine likes to work with intricate new software and tools to interpret and understand these data, to extract new information about galaxies and the stars within them.

Specifically, a continence and urogynaecology clinical nurse consultant. Join us as we speak about Sheena's journey to urology and continence nursing, why we should care more about our plumbing, and the personal, economic, and environmental impact of incontinence..
