Research interests
My main research interest is about how elements are made in stars, from small stars like our Sun, to the biggest stars that will explode as supernovae.
I am a member of several international collaborations focused on nuclear astrophysics, galactic archaeology and cosmochemistry, including NuGrid, the UK network BRIDGCE, JINA-CEE, the COST Action ChETEC, and the NSF Accelnet network IReNA.
Postgraduate supervision
Nuclear astrophysics, cosmochemistry, stellar evolution and nucleosynthesi
