Abstract: One of the most fulfilling aspects of studying resonant dynamics in galaxies is that it is central to a wide variety of astrophysical problems. It connects across scales, from star clusters to the cosmological context, and plays an essential role in a galaxy’s kinematic, chemical and morphological evolution. Galactic dynamics is therefore a multi-faceted problem that can benefit from pushing forward on many fronts. At Dartmouth, I expect to build a vibrant group working on multiple projects suited for scholars at all levels, from undergraduate to postdoctoral. In general, my approach is to start from first principles and systematically include a combination of innovative and well-established methods. I have successfully used this approach to make headway on a diverse array of topics, ranging from the efficiency of stellar radial migration to building a model that explains how super-escape velocity cluster stars can be in stable orbits that do not escape. My vision for the future is similarly broad and ambitious and has three major thrusts. These are to (1) gain insight into the nature of spiral structure, (2) use chrono-chemodynamic signatures to reveal the dynamical history of the Milky Way, and (3) decipher the formation mechanism for Boxy/Peanut shaped bulges in galaxies. In this seminar, I will detail these programs, and the physics that connects them. The results will provide a foundation for the interpretation of the current flood of data from precision surveys and high-resolution simulations. Long term, I envision (GD)^2 as providing a synergy between the existing strengths at Dartmouth and opening new avenues for innovative science.
