Our Team


Thomas Crawford – Founder & Chief Technical Officer. – Prof. Thomas Crawford is continuing his group’s basic research efforts to improve PTNM and adapt the platform to other applications. Dr. Crawford has over 16 years of experience with magnetic recording technology. As Associate Professor of Physics at the University of South Carolina, his group’s research has focused on advanced concepts in nano magnetism and magnetic materials particularly studying magnetic field directed self-assembly of magnetic nanoparticles using extreme field gradients found at the surface of magnetic media. Prior to joining the faculty at South Carolina, Crawford was a research staff member at Seagate Research where he helped invent and test advanced write head concepts. Crawford was a NRC postdoctoral associate at NIST-Boulder, and graduated with a Ph.D. in physics from the University of Colorado Boulder. Over his career, Crawford has co-authored 51 publications and holds 12 issued patents, including a patent on the use of recording media to assemble nanoparticles.

Tyler Tatum – Chief Customer Officer – Tyler has over 15 years of experience in technology focused startup ventures, including 10 years in a management / leadership role. Tyler’s core strength is his ability to turn customer needs into marketable products by facilitating communication between business leaders, current and prospective customers and technology developers. At Ripple Technology Tyler has increased small business revenue (e.g. SBIR/STTR grant activities), helped expand operations into Alabama, Florida and South Carolina, and optimized Ripple’s sales process. Prior to Ripple Technology, Tyler Tatum served as Brainlike’s Chief Executive Officer, where he built revenues from zero to $1 million dollars a year with no outside investment. During his tenure at Brainlike, he was able to acquire over $3 million in defense SBIR / STTR funding. (www. linkedin.com/in/tylertatum )


Our Work


Using Pattern Transfer NanoManufacturing (PTNM™) platform, MagAssemble manufactures nano-to-micro scale custom patterns with ~10 nanometer resolution and nanometer-to-centimeter areas to create optical coatings and diffractive optical elements.

The MagAssemble nanomanufacturing process creates templates which organize ferrous nanoparticles (~10 nm diameter) into nanopartice patterns. These nanoparticle patterns can then be used to create both simple and complex optical designs/functionalities for optical systems such as fiber optics, lenses, and optical sensors.

The nanopatterns can be directly built into not only flat surfaces of Si, glass, fused silica and optical fibers to create high quality, robust and miniaturized optical components, but also curve surfaces of lenses to reduce design complexity and component weight.

These functionalities can be realized without sacrificing PTNM’s low cost and simplicity, which commercial alternatives currently can’t provide.

MagAssemble has demonstrated prototype PTNM™ optical coatings, high efficiency reflection Si and transmission SiO2 diffraction gratings, and pump (980 nm)-signal (C band) combiners.
