Biography

I am a Professor of Astrophysics. I got a PhD in Astrophysics at the University of Bologna (Italy), after which I have been post-doctoral fellow at the Ludwig-Maximillian University of Munich (Germany) and the Max-Planck Institute for extra-terrestrial physics (MPE) in Garching (Germany). In 2005 I was awarded a Marie-Curie fellowship which I spent at the University of Oxford (UK). In 2007 I was awarded a Marie-Curie Excellence Team Grant with which I joined the University of Portsmouth (UK), as senior lecturer in 2007 and Reader since 2009.

My expertise is the modelling of the spectro-photometric and mass properties of galaxies. These so-called Stellar Population Models find ubiquitous applications in astrophysics and cosmology. In particular, they are the tool to study galaxy formation and evolution both theoretically and by interpreting data. The models I calculate are publicly available at: www.maraston.eu.

Research interests

Stellar Population modelling, galaxy evolution modelling, high-redshift galaxies, globular clusters.
