Mechanical Engineering Division - Structural Engineering DepartmentI write proposals, manage technical efforts, complete reports, and occasionally support fellow engineers with their projects.The majority of my work revolves around destructive and non-destructive testing and test automation. Types of tests I have conducted include: hydrostatic, pressure cycling, burst, fatigue, static load, and corrosion testing. These tests typically include measurement of pressure, force, temperature, and/or strain. I have worked with a variety of test and measurement hardware and software. I'm familiar with PID controllers and PLCs. I'm fluent with programming using NI Labview and Matlab. When planning for hazardous tests, I perform routine safety assessments that includes a job safety analyses (JSA). Some projects require design and fabrication of test fixtures. For these projects I utilize solid modeling software packages to generate CAD drawings used by machine shops. I also attend conferences and expos to promote future endeavors for the company.I've managed programs for accelerated corrosion testing on pipes in corrosion under insulation (CUI) environments and testing on hydrogen and compressed natural gas fuel tanks for the automotive industry. For corrosion projects, measurements have included electrochemical impedance spectroscopy (EIS), linear polarization resistance (LPR), and open circuit potential (OCP). For fuel tank testing, I have developed capabilities that include pressure cycling in extreme temperature environments and led multi-division programs that include bonfire testing, gunfire testing, pendulum impact, and drop testing. All of these test efforts have revolved around automotive regulatory test standards.Recently I've worked on programs involving vacuum and pressure testing for aircraft transparencies.

Chemistry and Chemical Engineering Division - Fire Technology Department - Fire Resistance SectionMy work here consisted of managing test programs to determine the material flamability or fire resistance of consumer products and materials for the construction, marine, and oil & gas industries. I gained valuable experience writing proposals and reports, conducting experiments, and presenting technical papers at conferences. I worked closely with chemists and fire protection engineers and learned a great deal in each respective field.Specific accomplishments include:Generating transient heat transfer models using off the shelf software and using MatLAB codingDeveloping the group's capaibility related to computer modeling by selecting appropriate software packages and overseeing the selection & acquisition of a 16-core expandable workstation for computer simulationsCompleting several internally funded research & development programsRunning Genetic Algorithm optimization code within MatLAB to determine thermal properties of insulation materialsOverseeing the selection & acquisition of a high temperature Netzsch TGA/DSC thermal analyzerDeveloping Lithium Ion Battery and Ultra capacitor test capabilitiesGaining an in-depth understanding of oxygen consumption calorimetry as it relates to heat release rate and general fire testingFamiliarity with NFPA, ASTM, ISO and other standards organizations' test procedures.

I worked on a venture opportunity using ultrasonic transducers to break down micro-particles of various sizes and compositions. Analysis of tested samples was conducted on a Scanning Electron Microscope (SEM).

I assisted the Computational Engineering Team by performing custom testing and modeling of a thick-film heater in order to validate a new software package, COMSOL Multiphysics. I worked with 2-D & 3-D heat transfer models, created Solid Works macros that interfaced with Microsoft Excel for custom drawings, and worked with Matlab and Excel to process test data.
