About

I am a Royal Society Career Development Fellow in the Astrophysics Group of Imperial College London. I combine theoretical modelling and computer simulations to build a coherent picture of how gas and dust evolve and interact in planet-forming environments, ultimately giving rise to planets. By comparing model predictions with observations of planet-forming environments and extra-solar planets, I aim to develop a predictive theory of planet formation and help interpret what we observe with telescopes.

My expertise lies in modelling the complex interplay between dust microphysics, gas ionisation and magnetic processes, and how these processes shape the long-term evolution of planet-forming environments. I have developed a unique numerical framework for these environments that couples the long-term evolution of their gas and dust content, including dust growth and dynamics, with nonideal magnetohydrodynamic calculations. I use this framework to understand how, when and where the building blocks of planets form.
