Bruker Daltonics

Senior Electronics Design Engineer / Electronics Engineering Manager

May 2010 to December 2014 

Initially  worked as a Senior Electronics Design Engineer and then became manager  of a new Electronics and Firmware group (8 people) in the fall of 2012.

Was  Principal Electronics Designer for 2 scientific instruments.  Each  instrument had 8-10 modules and several dozen PC boards.  Designs  included 3KV RF voltage amplifiers with large air core resonant  inductors and ultra-stable feedback control, +/- 350V DC amplifiers, DSP  based module controllers, Temperature, Pressure and Vacuum Control,  Filament Emission Current Regulator, Data Acquisition Module and System  Power and Interconnect Design. 

More recently was  the main hardware architect for the design of a new digital platform for  communicating between electronic modules inside an instrument and  between the instrument and a PC.  This involved the design of an ARM  processor based controller with a Cyclone V FPGA and a daughter board  that allowed scan and acquisition control and inter-module  communications to be tested.

Varian, Inc.

Senior Electronics Design Engineer

March 2001 to May 2010

Was the Principal Electronics Design Engineer for several analytical instrumentation product designs.  Designed +/- 6 KV voltage switching electronics, a data acquisition board that ran 5 KV away from ground potential, a new DSP based controller board with USB interface, PID controlled heater circuits, an ion gauge controller circuit, pressure regulation circuits, and a full set of diagnostic circuitry and self-test programs.  Supported EMI and safety certification of final instruments.

Bear Instruments, Inc.  

Principal Electronics Engineer

March 1994 to March 2001

Was one of the 3 founders of Bear Instruments and the Principal  Electronics Engineer.  Bear Instruments designed and manufactured a  small Bench Top Mass Spectrometer.  The product design was the first of  its kind and it dramatically decreasing the size of a Triple Quadrupole  Mass Spectrometer.  Was responsible for all the electronics in the  product and for assisting with day to day business activities as an  officer of the company.

Finnigan MAT (Now Thermo Fisher Scientific)  

Electronics Design Engineer 

Was the main Electronics Engineer on a project designing a new  Scientific  Instrument.  Designed over 2 dozen PC boards, wrote software  in C, evaluated the final system for analytical instrument performance,  noise performance, temperature drift, and EMC making improvements as  needed.
