I do have experience with precision control of fludics, perhaps not micro-fluidics per say.
My work experience is in developing controls based electronic systems for a variety of industries.
The examples you mentioned - MEMS, lab-on-a-chip would require specialized equipment to develop - which I obviously don't have access to.
What I could develop are systems _using_ MEMs if it is provided to me.
In the case of lab-on-a-chip, i could develop systems that operate to perform certain (electronic / controls based) actions on the chip. e.g. precision pumps, valve actuation, heating/cooling, pressure inducement, lazing, ultrasonic vibration or disruption.. etc. Perhaps developing a precision pump for instance, if there was a commercial need for it for instance.
Anyway, if you'd like to converse in email offline, do let me know.
Even if there's nothing promising we can work on in the immediate future, perhaps there might something further down the road where we could.
