The long-term objective of my research program is to understand how planetary surfaces evolve over time, and characterize the processes working to shape these landscapes. To achieve these goals, I will study the morphology and distribution of impact craters on the surface of planets and satellites in the solar system. Impact cratering is a ubiquitous process in the solar system, with most planets and moons retaining thousands of scars from past impacts. By comparing fresh craters on airless worlds to their more degraded counterparts on planets with atmospheres, we can quantify the amount of modification that has occurred and constrain the processes that affect the evolution of planetary surfaces.

我的研究计划的长期目标是了解行星表面如何随着时间的推移而演变，并描述塑造这些景观的过程。为了实现这些目标，我将研究太阳系行星和卫星表面撞击坑的形态和分布。撞击坑在太阳系中是一个普遍存在的过程，大多数行星和卫星都保留着过去撞击留下的数千个疤痕。通过将无空气世界上的新陨石坑与有大气层的行星上更退化的陨石坑进行比较，我们可以量化已经发生的修改量，并限制影响行星表面演变的过程。
