Exploring Interdisciplinary Research at Duke via Ph.D. Committees
1st Place - 2018 Scholars@Duke Visualization Challenge
2018 Scholars@Duke Visualization Challenge
Duke Scholars Bridge Disciplines to Tackle Big Questions
Description: By combining Duke Ph.D. committee membership data with the faculty appointments directory, connections between academic organizations were found and used to construct an undirected, weighted network (or graph). From this network communities of closely linked organizations were created via the Louvain method. Additionally, the level of interdisciplinary activity in each organization was measured by comparing the relative weights of their external and self connections. Analysis won 1st place in the competition.
Methods: Network analysis, Louvain method
Software: networkx, pandas, jupyter
ATLAS TRT Particle ID Machine Learning R&D StudiesSlides
Description: R&D studies of particle identification in the ATLAS Transition Radiation Tracker (TRT) where conducted utilizing machine learning techniques, with the goal of separating electron tracks from muons. Developed with fellow Duke graduate students Doug Davis and Sourav Sen, and continued by Davis and others within the TRT group. Support Vector Machines (SVM) and Boosted Decision Trees (BDT) from the scikit-learn library were tested, as well as Neural Networks (NN) in constructed in Keras+TensorFlow.
Methods: SVM, BDT, NN, k-fold Cross-Validation
Software: scikit-learn, keras, tensorflow
Numerical Methods and the Dampened, Driven PendulumPaper
Description: A computational study of the dampened, driven pendulum using the Euler-Cromer and Rung-Kutta numerical methods to investigate resonance, nonlinear behavior, and chaos. Numerical simulations compared to theory where possible.
Methods: Euler-Cromer, Rung-Kutta, Ordinary Differential Equations, Chaos and Lyapunov Exponents
Software: numpy, matplotlib
My research interest is experimental particle physics at the LHC, specifically the ATLAS experiment. Based at Duke University I analyze data and write code, focusing on jet physics with my advisor Prof. Ayana Arce.
Multi-b Jet Search:
Currently I am researching new physics beyond the standard model with the multi-b search. We are looking for supersymmetric (SUSY) particles, gluinos in this case, that decay to multiple b-quark jets plus missing energy. This research will form my PhD thesis.
- Search for supersymmetry in final states with missing transverse momentum and multiple b-jets in proton-proton collisions at sqrt(s) = 13 TeV with the ATLAS detector - 2018
Large-Radius Jet Calibration:
For my qualification task to earn ATLAS authorship I developed a data driven jet energy scale (in-situ JES) calibration for large-radius jets. I am responsible for the photon-jet direct balance portion of the combined calibration, which uses momentum conservation to calibrate the large-radius jet by balancing it with a well-measured photon.
