Nonlocal Modeling

Corrosion adversely affects the performance of metal alloys that are widely used as structural materials in the automobile, naval, and aircraft industries. Currently I am working on building a multiphase nonlocal model to better capture the process of corrosion. This work was initially funded by Naval Air Systems Command (NAVAIR) through a Small Business Technology Transfer (STTR) program, Contract No. N68335-15C-0032, awarded to Advanced Cooling Technologies, Inc. (ACT) in collaboration with Florida State University (FSU).

Quantum Optics

One of the interesting phenomena of quantum mechanics is the concept of a quantum jump, where a system will switch between two discrete states. This behavior is most commonly seen with respect to the electron transition between energy levels of an atom. I was involved in studying the collective quantum jumps of Rydberg atoms. The large dipole moment of the highly excited Rydberg atom causes a shift in the energy levels of surrounding atoms. My area of research pertained to collections of Rydberg atoms that exhibit quantum jumps when driven off resonance ( paper/ talk/ poster ).

Organic Solar Cells

I developed a solar cell characterization station to source voltage and measure current on organic solar cells (OSC) that were fabricated in the laboratory. Before the fabrication process could begin, the design of the testing station needed completion as well as a run of efficiency tests on a commercial solar cells to calibrate the whole characterization apparatus. After the OSC’s were spin coated, optical images were taken as well as atomic force microscopy (AFM) on the samples to characterize the topology of the thin films ( paper/ talk/ poster ).

Vega-Lite

Vega-Lite is a high-level grammar of interactive graphics. It provides a concise JSON syntax for rapidly generating visualizations to support analysis. I have also submitted documentation and examples to the Vega-Lite project. I was made a contributing member to the vega-datasets repository which acts as a common source for example datasets used by Vega-related projects

Crnpy

The corrosion research I have been working on involves modeling a variable chemical reaction network (crn). As networks grow larger the computational cost of running dynamic simulations increases significantly. I have contributed code to the crnpy python library to speed up simulation time utilizing vectorized routines.

Florida State University

Through my study of physics I developed an interest in programming and computers. I am now at Florida State University pursuing a PhD in the emerging field of Scientific Computing. My background in physics and mathematics has allowed me to take on many of the challenging scientific problems.

Appalachian State University

I have a bachelors degree in physics from Appalachian State University, where I studied the fabrication and characterization of organic solar cells ( paper/ talk/ poster ). I also was involved in the modeling of voting trends in North Carolina using decision trees and random forests (poster).
