Our Coronavirus Guidance

So that we can ensure that all Members of the Churchill College community stay healthy and safe, things will look a little different when you next come to College. But you can find everything you need to know on our new Coronavirus Guidance page  From the latest research from the University to what you should do if you have symptoms, and from the provision of College services to minimising the risk of transmission, you'll find all the answers to your questions here.

Dr Sergio Martin Alvarez

Subject Astrophysics & Cosmology
Fellow type Postdoctoral By-Fellows
Year started 2019


Sergio Martin Alvarez obtained his Physics undergraduate and master’s degrees at the University of Valencia. He was awarded a PhD in Astrophysics by the University of Oxford, investigating in his thesis the origin of galactic magnetic fields and the role these play in the formation and evolution of galaxies.

As a postdoc at the Institute of Astronomy and the Kavli Institute for Cosmology, his research employs massive cosmological magnetohydrodynamical numerical simulations to tackle complex open questions about the non-linear processes of structure formation in our Universe. His research aims to improve our understanding of the origin of the ubiquitous magnetic fields of the Cosmos and how these and other physics frequently unexplored in simulations, such as cosmic rays or radiation, contribute in turn to shape the formation of galaxies and solve the small scale challenges faced by the standard cosmological model ΛCDM (i.e. a Universe with cold dark matter and dark energy).
