Curriculum Vitae:

Agnes Ferte

My main interest is cosmology, the study of the universe as a whole. I have been working on two phases of acceleration of the expansion of the universe: cosmic inflation shortly after the Big Bang and the current acceleration that started around 5 billions years ago.

I have started by studying the polarized anisotropies of the cosmic microwave background as a probe of inflation and more generally of the physics during the primordial universe.

My main current research is now focused on the recent universe, trying to understand what causes the current acceleration of the universe: a dark energy? Or is it a hint of different laws of gravity on very large scales?

I am mainly using the weak gravitational lensing as a cosmological observable and joined the Dark Energy Survey in 2014 to tackle these questions. I participated to the cosmological results from the first year of observation where we confirmed weak lensing is a very promising probe of the recent universe.

I am now co-leading the Dark Energy Survey analysis team dedicated to test the different alternatives of the standard model of cosmology, specially to explain cosmic acceleration. I am also working on some challenges we will have to face in future weak lensing experiments (WFIRST, EUCLID, LSST).

I am also involved in public outreach and spread a bit of cosmology on twitter (@cosmologirl)
