These disks are\u003Cbr \/\u003E\r\nthe leftover remnants of planetary formation and can hold important clues in understanding the\u003Cbr \/\u003E\r\nevolution and history of planetary systems. Distinct features in a disk\u2019s morphology can\u003Cbr \/\u003E\r\nelucidate the architecture of an underlying planetary system or indicate the signatures of past\u003Cbr \/\u003E\r\nclose encounters with flyby stars. In this thesis I discuss both our Solar System debris disk, as\u003Cbr \/\u003E\r\nwell as that of an exoplanetary system: HD106906. Specifically, I use signs in the inclination\u003Cbr \/\u003E\r\ndistribution of the Kuiper Belt in our own Solar System to constrain the environment of our Solar\u003Cbr \/\u003E\r\nSystem\u2019s stellar birth cluster. I also use observations of unique features in the debris disk\u003Cbr \/\u003E\r\nsurrounding HD106906 to constrain its evolutionary history and propose a unique formation\u003Cbr \/\u003E\r\ntheory for this unusual system. My results provide a link between the present configuration of a\u003Cbr \/\u003E\r\nsystem\u2019s debris disk and the dynamical history of the system itself.\u003Cbr \/\u003E\r\nBeyond debris disks, I then explore the role of planetary orbital dynamics on habitability. I\u003Cbr \/\u003E\r\nconsidered an external perturber on young planetary systems through the dynamical mechanism\u003Cbr \/\u003E\r\nknown as evection resonance and discuss the implications that this mechanism may have in\u003Cbr \/\u003E\r\nincreasing the habitability of planets in such systems.\u003Cbr \/\u003E\r\nCommittee\u003Cbr \/\u003E\r\n\u2022 Dr. Gongjie Li \u2013 School of Physics\u003Cbr \/\u003E\r\n\u2022 Dr. John Wise \u2013 School of Physics\u003Cbr \/\u003E\r\n\u2022 Dr. Surabhi Sachdev \u2013 School of Physics\u003Cbr \/\u003E\r\n\u2022 Dr. James Wray \u2013 School of Earth \u0026amp; Atmospheric Sciences\u003Cbr \/\u003E\r\n\u2022 Dr. Fred C.
