  GE Healthcare

  Jun 2010 - Sept 2010

  Engineering Intern

  Performed MR patient table docking and undocking force testing and developed analysis models based on table drawings, solid models, and prototypes. Proposed design changes to maximize table’s mechanical efficiency. Supported the effort to update patient table assemblies to RoHS compliance standards by updating component specifications, interacting with suppliers, and sourcing new components where required.
