Hannah Ross is a postdoctoral researcher in the Computational Cosmology Center (C3) working with Dr. Zarija Lukić. She graduated with an Msci in Natural Sciences (Physics and Computer Science) from Durham University in 2014 and received her PhD in astrophysics in September, 2018 from the University of Sussex working with Prof. Ilian Iliev.

Hannah's research focuses on large-scale cosmological simulations. Her main physics research interests include large-scale structure, dark matter, the the 21-cm signal from the epoch of re-ionization and cosmic dawn, the Lyman-α forest, and QSOs. She is a member of the SKA science team. Her computational interests focus on the improvement and development of fully-numerical codes to tackle astrophysical and cosmological problems.  Hannah is part of the EPC project ExaSky: Computing the Sky at Extreme Scales in which she is currently working on the development of the Nyx code and a comparison project with Hacc. She is also using the radiative transfer code C2-Ray to introduce more realistic re-ionization models into Nyx simulations.
