Projects

Selected engineering and automation projects across optics, mechatronics, and fabrication.

Automated Maskless Photoalignment

DMD projection, motorized polarizer, and confocal autofocus; ~2 μm features with repeatable focus and registration.

Optics LabVIEW Motion

Dynamic LC Cell Twist–Thickness–Temperature

Precision mechanism under a polarizing microscope with capacitance thickness sensing and LabVIEW automation.

Mechatronics Controls Thermal

Gas-Propelled Autoinjector Proprietary

R&D on a novel gas-propelled autoinjector: mechanism refinements, flow regulation, retraction timing, and end-to-end characterization in a hands-on team.

Mechatronics Test Thermo

Pancharatnam-Berry Lens Array

Six-element geometric-phase lens array patterned via multi-exposure azimuth fields; f ≈ 2.5 cm.

Optics Fabrication

3D Director Simulation Math→C Codegen

Mathematica-derived Euler–Lagrange, auto-generated C kernels, flexible 3D director relaxation.

Simulation Numerical Methods

Kite Aerial Photography Rig

Pre-drone RC pan/tilt, Picavet self-leveling, and a mechanical shutter actuator; 40+ custom parts.

Mechanisms RC Fabrication

Elastium SMA Casting Proprietary

Controls and integration on a continuous-casting furnace; responsibilities only, no media.

Controls Systems

Focus Areas

I design, build, and validate instruments that blend mechanics, optics, and electronics. My work spans applied R&D, hands-on pedagogy, and simulation—quick two-sentence snapshots here, with deeper dives available on request.

Teaching

I developed instrumentation-rich labs, capstone experiences, and design clinics that bridge theory with build skills. My classes emphasize iterative prototyping, documentation, and team execution.

Science

PhD work in liquid-crystal photonics delivered maskless alignment tools, tunable optics, and precision metrology. I translate research instruments into reliable lab systems ready for collaborators.

Computation

I pair Mathematica-derived models with compiled kernels and Python toolchains for fast iteration. From inverse design to controls, my workflows turn math into maintainable code and visualization.

Education

2015

Kent State University

Ph.D. Chemical Physics

Kent, Ohio

Advisor: Prof. Hiroshi Yokoyama

Dissertation: Artificial Microscopic Structures in Nematic Liquid Crystals Created by Patterned Photoalignment and Controlled Confinement: Instrumentation, Fabrication and Characterization

Developed custom optical instrumentation and automation software to study the structure and behavior of nematic liquid crystals. Work combined theoretical modeling, materials fabrication, and advanced microscopy techniques to enable novel experiments in surface anchoring, defect energetics, and optical phase control.

2008

Cal Poly

B.S. Physics

San Luis Obispo, California

Completed a rigorous, hands-on physics program at Cal Poly, with coursework in classical mechanics, electromagnetism, thermodynamics, quantum mechanics, and experimental design. The university’s “learn by doing” philosophy provided early exposure to electronics, instrumentation, and laboratory methods—laying the groundwork for both graduate research and technical problem-solving in industry.

2006

Sherburne Sculptures

Apprentice Machinist

Atascadero, California

Gained foundational experience in machining and fabrication while apprenticing under a precision machinist. Learned manual milling, lathe work, toolmaking, and the fundamentals of part tolerances and material behavior. This early hands-on training sparked a lifelong passion for designing and building physical systems.
