• Principal Design Engineer

  • Mar 2009 - Present

  Acted as a technical lead for the electrical development of a patient monitor- Acted as part of an interface to an industrial design group.- Worked with a contract manufacturing group to review the design for manufacturability and coordinate prototype builds.- Worked with board fab houses to specify PCB stackups and layout rules to meet controlled impedance requirements.- Managed the work of a layout contractor.- Acted as an interface to a compliance lab.- Worked with the automated test group to support test fixture development.Mixed Signal IC Design - Designed the Stimulation Output stage for a next generation Neurostimulator- Transistor level design of the analog circuit including creating schematics and running simulations.- Reviewed the layout of the analog block and its connections to other analog blocks.- Acted as an interface to the foundry.- Designed a digital circuit to interface to the analog design and verified it on a FPGA.- Verified the behavior of the final chip on the bench.Formal Verification of Product Requirements- Created Verification Protocols, reviewed them with Quality, ran the protocols and filed results.Implant PCB and Custom IC packaging Interposer Layer- Worked with a layout engineer and mechanical engineer to review and revise the route in the neurostimulator PCB and the interposer layer in the custom IC packing to prevent unwanted signal coupling.- Performed risk analysis of possible single point failures.

• Sr. Design Engineer

  • Mar 2005 - Mar 2009

  - Program manager for an embedded system development. This included creating schedules, writing product requirements, creating risk documentation, participating in system level design discussions, creating verification plans, and working through compliance testing.- Designed a power management strategy for a next-generation neurostimulator.- Designed a data compression circuit to increase the data storage of the neurostimulator by up to 33%.- Created the schematics for and oversaw the layout of the system-level implant PCB in the current generation neurostimulator produced by Neuropace.

• Design Engineer

  • Mar 2000 - Mar 2005

  - Designed an FPGA based printed circuit board system which acted as an early model of the implantable neurostimulator. This system was used in early clinical trials to demonstrate safety of the system.- Designed a digital circuit block to reduce the workload of the micro controller in processing patient data.- Performed research to find the cause of a current leak / instability problem in a custom IC. Designed several FIB experiments to isolate the issue.



Indigo Systems (acquired by FLIR in 2003)

• Design Engineer

  • 1999 - 2000

  - Created fully custom layouts for the integrated circuits design group. This included running DRC and LVS checks to ensure foundry layout rules were met. - Performed an analysis of power distribution nets to ensure IR drop requirements were met. - Created fully custom layouts for the integrated circuits design group.
