Education

The College of Wooster, Wooster, OH Graduation May 2017 Degree: Bachelor of Arts in Physics and Philosophy GPA: 3.587 Honors: Dean’s List of Academic Excellence, International Scholarship, Departmental honor, Phi Sigma Tau Honor Society Senior Independent Study Thesis (Phil & Phys combined): 1-yr research and writing project that resulted in an 80-page paper, two oral presentations, one poster presentation, and one 2-hr oral defense; examined the concept of mental causation by analyzing physical systems such as Ammonia molecules, Fluid convection cell, ideal gas and logistic growth toy model. Research Experience

SoREP (Sophomore Research Program), College of Wooster Aug. 2015 – Dec. 2015 Research Assistant

This New Horizon Flyby inspired project aimed to simulate the chaotic dynamic of Pluto-Charon planetary system through numerical integration of the equations of motion

Applied exact solutions from for the special scenarios; obtained time-space plots, 72-hr Poincare, parametric plots and the animation of the system

Physics REU (Research for Undergraduate), College of Wooster May 2014 – July 2014 Research Assistant

A full-time research project over the course of 10 weeks to study the gravitational Interaction of three massive rods through numerical integration; Obtained the information of nonlinear dynamics between multiple asteroids in space

Obtained the exact solutions for the extended versions of Newton’s two body problem, Lagrange’s three body problem, Euler’s three-body problem as well as Moore’s “figure 8” orbit

Analyzed the data under different NDSolve command options to maximize the accuracy and speed of numerical integration; Performed concurrent computing on 13 computers over 12 days for the largest data collection; Generated the sonification, the space-time plots and the animations of the dynamical systems

Co-authored - Dynamics of Three Gravitating Rods” that will be published in 2018; gave the poster and oral presentations on campus and in 2015 APS March conference

Computational, Analysis and Laboratory Experience

Created various models such as 3D motion of restricted 3-body problem projectile using variable time step for reduced integration steps near central force of Kepler structures under different force laws, with various components stored in structures

Created various interactive simulations such as quantum scattering, 2D Ising ferromagnetism model, Duffing oscillators, rotating rigid body, and 3D projection of hypercube that allow the users to control a great range of initial & boundary conditions, distinct integration algorithms, drawing style, animation speed et cetara

Experiments such as Coulomb charge balance, Cavendish torsion balance, Feynman single photon double slits, and Kamerlingh Onnes superconductivity experiments, that require careful handlings of the lenses and lasers, fine tunings of the tension band or balance arm, attention to details, independent thinking, and analysis of large collection of data;

Each experiment was documented in lab notebook and resulted in a formal lab based on the data analysis; the self-designed project included a 10 pages formal lab report, the web article, the project proposal, the grant proposal and an oral presentation Leadership
