There are several key themes, spanning planetary science and planetary dynamics, that I propose to research during my PhD. These include,The dynamics of small bodies in different planetary system - how does the host star affect the scattering of comets and asteroids, through the scattering rate, accretion efficiency, and resulting impact velocities?How do these impacts affect the evolution of the Earth, and exoplanets more generally, such as through the impacts on prebiotic conditions. From this I will try and understand when, and how many volatiles are delivered to rocky planets.Studying planetary systems around white dwarfs, as this is a powerful way of understanding the composition of the exoplanetary debris in these planetary systems.

有几个关键主题，横跨行星科学和行星动力学，我打算在我的博士学位期间研究。这些问题包括，不同行星系统中小型天体的动力学--宿主恒星如何通过散射率、吸积效率和由此产生的撞击速度影响彗星和小行星的散射？这些影响如何影响地球和更广泛地说系外行星的演化，例如通过对生命前条件的影响。研究白矮星周围的行星系统，因为这是了解这些行星系统中系外行星碎片组成的有力途径。
