I then validated my work using simulations and predicted its signi鍖cance via modeling. The results will likely be included in the next generation of textbooks on galactic dynamics. Extensively used the following applied mathematics techniques: perturbation theory, chaos, non-linear dynamics, and hyper-geometric functions Constructed statistical models based on distribution functions using object oriented program- ming in C++ and Python. The results will be used in future semi-analytic galaxy models and to interpret the results of galaxy simulations Built, debugged and implemented a numerical integrator to simulate gravity in a complex potential using C++ to numerically test and con鍖rm the robustness of my analytic theories Mined, analyzed and visualized spectral data from the 25 TB Sloan Digital Sky Survey database and Gemini Deep Deep Survey using SQL and IDL Received over $162,500 in fellowships and other awards to support my independent studies, plus over $13,000 toward travel expenses International Summer Institute for Modeling in Astrophysics Gravitational Dynamics, CITA, University of Toronto, Toronto, Canada Summer 2014 Was one of two US citizens chosen to be a student participant in this highly selective workshop, with 30 student participants from around the world. I formulated a method to solve the most ambitious problem presented at the workshop. My proposal was accepted and I collaborated in a small group on this project. Constructed an analytic distribution function that can be numerically integrated to derive multiple statistical properties of certain stellar systems Built an object oriented numerical integrator in Python to quantify the stability of the distri- bution function Awarded travel and tuition fellowships from both CITA and JHU as an incentive to attend Also Kathryne J.

International Gaia Schools Galactic Dynamics in the Times of Gaia & other Great Surveys, Mexico City, Mexico November 2013 GREAT ITN School: Galaxy Modeling, Besan存con, France October 2012 Gaia is a space telescope mission launched in December 2013 and manufactured by the European Space Agency. It will measure the positions, motions and spectra of over a billion stars with unprecedented accuracy, each more than 70 times over 5 years resulting in over a PB of data. International Gaia Schools are exclusive and typically for European students only, but I was accepted as an exceptional case. We were trained to mine, interpret and analyze Gaia data and then collaborated in small groups to perform original science experiments to determine the power and limitations of the mission. Produced simulated Gaia data from analytic models and large scale simulations of galaxies and analyzed how observational uncertainties could a鍖ect the science results The 2010 Summer School for Astro-Computing: Galaxy Simulations UC High Performance Astro-Computing Center, Santa Cruz, CA, USA Summer 2010 Gained intimate knowledge of the underlying mathematics and structure, and therefore the strengths and weaknesses, of various galaxy simulation packages in order to correctly analyze the simulated data and to critically scrutinize published results.
