Read/write cantilevers for nano-scale AFM data storage
Designed, fabricated and tested 1-micron-thick silicon cantilevers with integrated piezoresistive sensors (for bit sensing); or with integrated heaters (for bit writing on a plastic substrate) in Stanford/IBM collaboration. Invented dual-axis cantilevers for orthogonal sensing. Devices were precursors to "Millipede" probe-array-based mass storage project at IBM Zurich.
Micro-grating devices for fiber-optic networks
As employee #2 in Lightconnect, Inc., played major role in development of optical MEMS devices for fiber-optic networks. Performed design, layout and hands-on fabrication of prototype chips. Acted as liaison with commercial foundry. Helped company grow from 2 to 60 employees in three years. Company (now part of Neophotonics Inc.) is now a well-established provider of dynamic optical components such as MEMS-based variable optical attenuators and dynamic channel equalizers.

Custom thin cantilevers for MRFM
Produced POV-RAYTM-based scientific animation clip for IBM’s MRFM experiment (click here to download 25MB mpeg movie from IBM's website--may take a few minutes).
Piezoresistive levers for biotech applications
Led process-development and fabrication efforts on piezoresistive cantilevers for biological applications at Institute of Microtechnology, Neuchatel, Switzerland. Introduced process flow that successfully produced functional device prototypes on first run.
