Lecturer: Engineering MechanicsMississippi State University Aug 2020 - PresentMississippi State, Ms, Us• Reformed a PhD level course in advanced dynamics to include computational component. Traditional course focused on derivations of equations of motion only. Reformulated course taught students symbolic programming, numerical solution, and mechanism animation of advanced problems using MATLAB.• Taught Dynamics undergraduate course. Taught PhD level courses in Advanced Dynamics.• Highly successful delivery of online, PhD level coursework to support the university during a pandemic environment. -

Research Mechanical EngineerU.S. Army Engineer Research And Development Center (Erdc) Jul 2019 - Jun 2022Vicksburg, Ms, Us• Used ABAQUS to perform probabilistic (load resistance factor design) finite element modeling on spillway gates. Used MATLAB to perform statistical analysis on load and resistance data, including generation of numerical probability density functions from field data.• Technical reviewer for reliability/ load resistance factor design (LRFD). • Used proprietary C++ discrete element method codes to solve a coupled set of thousands of ordinary differential equations and integrate them forward in time in support of a sea ice mechanics project. Characterized sea ice fracture in the Beaufort Sea region.• Used FORTRAN to investigate high order methods in finite element elastodynamics research.• Formulated novel techniques to mitigate Runge’s phenomenon for high-order discretizations in support of a boundary element research project.• Wrote and submitted multiple DoD proposals in integral equations, generating high interest. -
Advanced Studies In Integral Equations ProjectMississippi State University Aug 2017 - Jul 2019Mississippi State, Ms, Us• Published peer-reviewed manuscripts in the area of Integral Equations.• Formulated novel high-order algorithms in integral equations from scratch and applied them to modern problems. Wrote supporting computer codes from scratch in FORTRAN, MATLAB. Increased accuracy over the state of the art by over four orders of magnitude.• Developed advanced numerical integration techniques for singular integrals. Substantially increased accuracy over conventional methods. -
