- Design changes to wingbox primary structure through CATIA V5, ENOVIA LCA, Siemens PDM, and more.- Coordinate with process teams and factory floor to ensure seamless change- Resolved electromagnetic effects non-compliance of 14 CFR 25.981 in the nacelle fitting installation through root cause analysis, allowing for a 10% hole oversize coverage to facilitate assembly.- Developed an annual Boeing Commercial Airplanes Structures-wide training on EME threats and protection design features to reduce non-compliances as a Corrective Action for the previous non-compliance.- Wrote Python scripts to automatically search for engineering documents, download them, and sort through them based on inclusion of key terms, reducing large data survey timelines.BCA Opportunities for New Experiences (ONE): Plasma Engine- Lead COMSOL analyst, parametrizing electric and magnetic fields to optimize physical plasma thruster tests.- Modeled and 3D-printed tooling and test fixtures for speedy assembly and modular testing.

Boston, Massachusetts, United States

• Oversaw multiple groups of engineering projects impacting people with disabilities and mediated client and student interactions.

Boston, Massachusetts, United States

• Designed and prototyped a mechanical, FDM-built PLA device for blind and deaf people to use while pouring drinks to tactilely indicate the optimal liquid level in the cup.

Boston, Massachusetts, United States

• Developed a method of converting 2D images of pre-braille text into 3D-printable models using computer software.• Edited and 3D-printed scans of pre-braille text that were displayed at Blind Culture Artifact exhibits at the Perkins School of the Blind in Cambridge, MA, Harvard University, Northeastern University, and the Boston Public Library.

• Analyzed DEM data of potential fault-case landings of the Earth Entry System (EES) for Mars Sample Return (MSR) using ArcGIS and MATLAB to determine optimal helicopter recovery landing sites which drove EDL-phase decisions.• Initiated mechanical designs of a containment system for the EES returning Martian samples to Earth, using decision matrices for recommendations in categories such as materials, shock absorption, recovery operations, and thermal controls.

Malibu, California

• Conducted and analyzed a heat treatment study of Selective Laser Melted (SLM) functionalized aluminum -6000 and -7000 series to maximize hardness by determining the optimal precipitation hardening processes for T6 and T7 tempers.• Performed metallurgical processes by setting up and breaking down SLM printer, mounting and polishing the printed samples, and analyzing their densities, hardness, and tensile strengths as well as their compositions through SEM.

Boston, Massachusetts, United States

• Led design reviews of 3D-models of the plane to detail critical model alterations needed, presented flight mechanics courses, and taught students best design intent practices when modeling with SolidWorks.• Assigned design or research tasks to 12 members and assessed their progress each meeting, ensuring they understood what they were doing and why they were doing it.

Boston, Massachusetts, United States

• Designed components for an all-electric, controllable plane to compete in the SAE Aero Design Micro-Class competition.• Foam-cut wings and assembled the plane for test flights to then assess areas of improvement, such as weight distribution.

Boston, Massachusetts, United States

• Constructed fiberglass and wood body of a rocket using rotary tools, laser cutters, and other machinery.• Assembled rocket for tests to compete in the NASA Student Launch competition, reaching a max height of 5481 feet.

Beverly, Massachusetts

• Designed mechanical fixtures using DFM and GD&T in SolidWorks, mechanically tested components by 3D-printing them with nylon and carbon fiber, and implemented them as aluminum and Teflon parts in automated liquid handling and storage machines, mechanically solving issues clients had with the machines.• Led design reviews of mechanical fixtures, assessing materials, costs, deadlines, and test procedures.

Boston, Massachusetts, United States

• Constructed “soft robotic” curling actuators by inserting highly compliant, silicone tubes into flexible exoskeletons to lift fruits, hourglasses, and other soft, fragile objects when filled with air.• Co-wrote Hybrid Fabrication of a Soft Bending Actuator with Casting and Additive Manufacturing, a paper explaining the hybrid fabrication of soft robotics that was published for the 2019 ASME Mechanisms and Robotics Conference.
