Cepheid · Molecular Diagnostics

• –Led mechanical architecture definition for an electromechanical subsystem — evaluated three concepts, owned detailed design and integration from concept through production.
• –Designed a closed-loop servo actuation system with magnetic and optical position feedback for precise, repeatable motion under tolerance and environmental variation.
• –Developed a voice-coil actuation concept as a cost-focused alternative, achieving a 60% unit cost reduction while meeting all performance targets.
• –Built an automated XY positioning stage using piezoelectric drives and machine vision for high-accuracy reagent placement.
• –Engineered magnetic capture mechanisms for sub-micron bead manipulation, optimizing mechanical and fluidic coupling.

Mechanical Engineer

Silverside Detectors · Radiation Security

• –Led mechanical design and system integration for two DARPA-funded radiation detection platforms — fixed and portable — integrating gamma/neutron sensors, cameras, and communications.
• –Owned the portable platform end-to-end: VoC definition, concept generation, detailed design, prototyping, and customer training.
• –Designed ruggedized architectures for portable operation with MIL-STD-810 compliant shock isolation and sealing strategies.
• –Performed structural FEA on enclosure and mounting assemblies to validate stiffness, strength, and load paths.
