In short, I tackle hard problems with large computers.
Feel free to reach out for collaboration on any of these topics.
Awarded >50M CPUh on the UK's DiRAC facilities, MEGATRON is the first cosmological simulation to self-consistently model the non-equilibrium chemistry and heating/cooling processes in the interstellar medium for nearly 100 atoms, ions, and molecules coupled to on-the-fly radiation transfer. Complete with state-of-the-art modules for galaxy formation and stellar feedback, including the formation and enrichment from Population III stars, MEGATRON models the formation of a Milky Way-like galaxy from the earliest epochs until cosmic noon.
An ambitious project to completely forward-model the spectra and photometry from the largest full-box cosmological radiation hydrodynamcis simulation of reionization with a resolved ISM.
The next generation of exascale codes require us to rethink even our most basic algorithms. This project is in its infant stages and uses a purely-local method to solve gravity in a cosmological setting.
