Research involving graphics simulation techniques, specifically those involving Eulerian-on-Lagrangian dynamics. My first project dealt with utilizing Eulerian-on-Lagrangian simulation in order to overcome problems with cloth collisions with sharp geometric object features. My second project introduces an efficient and flexible approach to articulated dynamics, and my specific contribution introduced an extension to Staggered Projections [Kaufman et al.] called Bilateral Staggered Projections.My third project deals with applying Eulerian-on-Lagrangian techniques in the muslce simulation domain.

Teaching assistant for the spring 2018 and spring 2019 computer graphics courses. Primary tasks involved grading homework assignments by compiling, running, and assessing code, holding office hours to help students with said assignments, and occasionally guest lecturing for the class on different graphics related topics.

Virtual

Developed the first stages of a prototype for hair grooming and simulating. Worked directly with the hair and cloth team to steer the development direction as the prototype progressed. Also worked closely to a number of artists and technical directors that would hopefully use the tool down the road to get gradual feedback and development direction. Worked entirely virtual and succeeded on developing a working prototype that the artists were able to play with near the end of the summer.

Improved production software by increasing spatial stability of hair curves.Increased the robustness of the solver by introducing temporal stability to hair curve edits.

Columbia, South Carolina Area

Head lab teaching assistant for two consecutive semesters of Algorithmic Design. This position involved running a a 2 hour lab session twice a week and assisting around 30 students with weekly lab programming assignments. Grading was also done for all of the students labs, lab reports, homework, and tests.

Worked on a continuation of undergraduate work to complete Masters ThesisThe project generated 3-Dimensional reconstructions of underwater cave tunnels using stereo video cameras. The project involved detecting and tracking features in a low light environment using motion tracking of a head lamp.This project also involved the reconstruction of 3-dimensional geometry based on limited point cloud and visual odometry data.ICRA 2017 - Underwater cave mapping using stereo vision

Columbia Sc

Research project awarded from Magellan Scholar undergraduate research grant. The project aims to generate 3-Dimensional reconstructions of underwater cave tunnels using stereo video cameras. The project involves detecting and tracking features in a low light environment using motion tracking of a head lamp.

Livermore, Ca

Created interactive web pages for displaying data visualizations with HTML5, javascript, jquery, and D3.js in order to improve workflow management. The final developed product was a standalone web page that could read simulation data and generate and interactive 2-Dimensional mesh, as well as an interactive parallel coordinate plot and stream graph for displaying mesh data.

Argonne, Il

Developed a visualization model for the output of water flow models. Created a python script to configure data visualized in Paraview.
