My primary research focus is on the connection between arithmetic dynamics and arithmetic geometry. Much of my work involves post-critically finite maps, which is a dynamical analogue of CM Abelian varieties. Additionally, I explore the use of dynamical Belyi maps in arithmetic dynamics to help us understand properties of PCF rational maps.
