I build instruments for the biotech industry. I have designed and constructed DNA chip synthesizers, DNA chip processing equipment, and other various instruments. I design mechanical, electronic, fluidics, optical, software, and in other disciplines. I have over 30 patents, many being multidisciplinary. I have used Solidworks, Pro Engineer, Autodesk products.
I wrote a program to convert DNA data sets to photomask writer files. This used an interpreter which I wrote to simplify photomask layout. I also wrote an equation parser to facilitate layout.
