Projects

  • 2024.09 - Present
    StentorCam
    Co-developed a low-cost robotic imaging system integrating a Raspberry Pi, custom Python code, a coaxial lens system, and a 3D-printed dark-field mask paired with an IR light-plate. Led the mechanical design and fabrication of modular 3D-printed components while contributing to both software development and experimental validation. The platform enables automated, high-throughput assays of light and chemical stimulation at roughly 1/20th the cost of commercial instruments.

    Tensegrity Structures
    Contributed to exploratory research on the design and mechanical behavior of tensegrity structures. Developed both experimental prototypes and display-quality models, beginning with a modular tensegrity system constructed from wooden dowels, rubber bands, and 3D-printed joints. Transitioned to advanced prototypes using stainless steel tubing, Kevlar cord, and precision-drilled fasteners, producing high-tension architectural forms now exhibited on the SFSU campus.
