• Continually worked with Speech and Neurodevelopment Lab to write Python script to enable efficient processing of large sums of data files. Properties of the script include:
• Updates master file with demographic data and measures of interest from new data files
• Graphs specific variables to find outliers and general data characteristics
• Saves lab countless hours processing testing data of new subjects
• Set up for future additional features if needed

• Derived equations of motion for six degree of freedom vibrational system
• Placed purchase orders and machine shop orders for designed parts
• Designed and built scaled down lateral control system model to test equations of motion
• Performed SolidWorks FEA on key design parts like rotary shaft and base plate
• Programmed code to measure displacements and motor frequency with Arduino
• Designed electrical circuit to supply correct PWM signals to micro-displacement sensors

Southborough, MA

• Set up tests and wrote procedures for peristaltic pump, brazing, ultrasonic bath, and tensile testing
• Set up temperature controllers and timer relay with shell heaters to corrosion test metals
• Tensile tested corrosion tested metals with Testometric Tensile Tester
• Wrote MATLAB and Python code to analyze and graph cyclic fuel cell data
• Designed and proposed coil heat exchanger to condense steam and performed energy calculations and CFD
• Created wiring diagrams and piping and instrumentation diagrams

Milford, MA

• Designed fixtures with SolidWorks and 3D printed them for testing
• Performed Instron stress testing and signal voltage output tests with SignalExpress
• Analyzed and processed Instron and SignalExpress data using Python code
• Performed FEA analysis using ANSYS software on varied pressure transducer designs
• Wrote engineering test reports and procedures
• Analyzed material cross-sections of pump heads under digital microscope and performed leak testing

Ipswich, MA

• Configured part, assembly, and dimensioned drawings in SolidWorks for valves. 400+ hours.
• Created and altered bill of materials using supply-chain management systems
• Conducted valve operational tests to track torque, current, and opening and closing times
• Reviewed and created design reports in MathCad
• Issued ECOs and ECNs and designed test fixtures
