PDE at Meta Reality Labs

Member and Treasurer of Northeastern University's Pi Tau Sigma chapter. Pi Tau Sigma is an international honor society for mechanical engineers. Duties as Treasurer include collecting membership dues and handling finances for events.

Product Design Engineer on the iPad Input Devices team.

• Analyzed and root caused major issue in reliability testing for a ramping product. Built prototypes, performed reliability testing and led FEA efforts to down-select material and geometry for a part that resolved issue.

• Led FMEA effort to de-risk battery fixturing design in next-generation product using analytical and simulation analysis. Designed 3 functional concepts and evaluated fit and performance with prototypes.

• Designed and led DFM efforts for major components in future releasing product. Collaborated with quality engineers to review, deviate and approve process capability reports for parts.

Designed opto-mechanical assemblies for various projects, including but not limited to:

• Mounting fixture for a pinhole to be mounted in front of a microscope objective which allowed for sub 10 micron, repeatable adjustment in 3 axes and rotation about one axis to < 1 degree. Design incorporated multiple types of flexures to achieve this degree of adjustability given very tight size constraints (40 mm max diameter). Applied tolerance stack-up analysis and GD&T to drawings.

• Assembly to aid in the alignment of the straightness of rails on Lenscheck system, using an interferometer and a series of fold mirrors and prisms. Designed custom mounting hardware and utilized a variety of off-the-shelf opto-mechanical components. Project required many modes of fine adjustment in multiple axes to ensure that all mirrors were in line with the laser emitted by the interferometer.

• Multiple smaller support projects for a longer term stereoscopic, automated focus microscope assembly. Designed custom tooling, including spanner wrenches and vacuum chucks, and completed 10’s of part drawings incorporating strict tolerances and GD&T. Designed and built a series of kinematic mounting fixtures to aid in the assembly and testing of the two halves of the system as well as the combined system.
