Eloy de Lera Acedo: Tiny signals, big ambitions

Have you ever looked at the sky at night and wondered about the mysteries of the universe? When most of us are just looking at those bright stars in awe, our guest today would be searching for tiny, minuscule signals that would help unlock the mysteries of the so-called Cosmic Dawn, when the universe went from dark to bright.

Eloy de Lera Acedo is an Associate Professor of Radio Cosmology and the head of the Radio Astronomy and Cosmology research group. His background in engineering and thirst of learning about the big science questions have led him to the Cavendish where he is involved in multiple international projects for new radio telescopes exploring a very, very infant universe.

So, with Eloy, we talk about the universe of course and how it went from darkness to radiant, but also about childhood curiosity, choosing between technical and theoretical knowledge, and about convincing people.

About the Podcast

People doing Physics
The podcast exploring the personal side of physics
As fascinating as physics can be, it can also seem very abstract, but behind each experiment and discovery stands a real person trying to understand the universe. Join us at the Cavendish Laboratory on the first Thursday of every month as we get up close and personal with the researchers, technicians, students, teachers, and people that are the beating heart of Cambridge University’s Physics department. Each episode also covers the most exciting and up-to-date physics news coming out of our labs. If you want to know what goes on behind the doors of a Physics department, are curious to know how people get into physics, or simply wonder what physicists think and dream about, listen in!
