Research Interests

My research interests focus on early Solar System processes. I aim to understand the evolution of the first solid bodies that formed around our Sun. These bodies, called planetesimals, were the building blocks of planets; those that remain in the Solar System today are known as asteroids. In my research, I use numerical models to quantify the collateral effects of hypervelocity collisions between planetesimals on their thermal and compaction histories. Projects that I am interested in include:

  • Simulations of collisions between self-gravitating porous planetesimals and the subsequent evolution of the thermal signatures left by impacts
  • Monte Carlo modelling to estimate the early impact histories of meteorite parent bodies
  • Mesoscale numerical modelling of compaction in primitive Solar System materials
  • Investigation of the effects of impact angle and target curvature upon cratering processes, including impact heating and crater morphology
  • Validation of the iSALE and iSALE3D hydrocodes against laboratory experiments
  • Numerical modelling of impacts into the oceans to determine the effect of the water depth on crater size and morphology
