Senior Verification Engineer in QA Group. ISC developed "Star-P", a software application allowing scientists and engineers to write applications in high-level languages for deployment on parallel computers. I expanded into my role as a generalist concerned with maintaining product quality. This included:
Monitoring and maintain the existing automated test systems. File bug reports as necessary.
Wrote a new subsystem for Python testing.
Wrote new tests in both Python and MATLAB to verify mathematical functionality of the Star-P product.
Acted as user advocate within the engineering organization. Wrote specs and use-cases as necessary to define user experience with Star-P.
Managed "test blitzes" and other large-scale test group activities.
Debug existing features and implement new features in the Star-P product itself when required.
Lead Electrical Engineer in On-Line Products Group. Sole electrical engineer responsible for board design in support of range of FTIR spectrometers. Selected projects include:
Designed and implemented "NG MiniMCB" control card for FTIR systems. NG MiniMCB is a mixed-signal card which controls the motion of the FTIR's mirror (constant velocity scan) and generates all timing signals used for data acquisition. Project included writing Verilog for Altera CPLD implementing a P+I control loop, design of analog circuitry supporting the P+I controller, and integration of Microchip dsPIC software for communication.
Designed and implemented "Dithermatic" optical preamp card for 2030 series MultiGas. Dithermatic incorporates a high-purity sine wave oscillator alongside optical preamp to reduce effects of A/D non-linearities and increase effective SNR when signal is digitized. Patent granted in 2006.
Designed, layed out, and implemented sensor board for auxiliary oxygen sensor sold as an add-on feature to the MultiGas FTIR, targeted to customers in the automotive engine industry.
Designed and implemented miniature bi-directional TEC control daughterboard to replace existing, commercial uni-directional TEC controller used in InDuct system.
Designed and implemented computer-controlled power distribution/sensor card for 2030D "Purity" FTIR gas analysis system.
Consultant. Created Electroniscript, a personal consulting vehicle for projects requiring interdisciplinary technical skills including systems, electronics, optics, and software design experience. Selected projects include:
Wrote field serivce manuals for MultiGas spectrometer under contract to MKS Instruments, (Methuen, MA). Work commissioned by the Director of Field Service. Over 500 pages of detailed service procedures (including text and photos) spread over 7 documents were produced. The materials are now part of the standard training program given to field service technicians.
Development of tutorials, applications notes, and training materials about parallel computing using MATLAB/StarP for Interactive Supercomputing, inc., (Waltham, MA). Work commissioned by the applications group for customer education and support. The materials have been used in classwork at MIT and Berkeley, amongst other places.
Various software and business consulting projects for Inveratech Corporation (Billerica, MA), including grant proposal preparation for DARPA and HSARPA.
Development of SDH/SONET system verification test suite in TCL/Expect for Axiowave Networks (Marlborough, MA).
Developed DC – 500 Mhz optical receiver for laboratory use. Designed and simulated the receiver using gEDA and ngSPICE. Then built and tested unit, and delivered prototypes to contacts at a couple of universities. The receiver was conceived as a potential stand-alone product.
Software developer for gEDA project. gEDA is a professional-level, GPLed CAD environment for electronic design on Linux. Specific contributions include enhanced SPICE netlister, gattrib (attibute management spreadsheet), documentation, and several smaller utilities. I also administered the Google Summer of Code program for the gEDA Project in 2008.
Consulting Engineer. Technical lead responsible for several aspects of the Axiowave product, including:
Systems engineering for large-scale MEMS-based optical cross-connect (OXC). Researched, developed, and documented OXC requirements and design specifications. The switch performance was governed by requirements culled from GR-253-CORE, GR-3009, and OIF-VSR4-05, amongst others. I tracked the progress of various evolving standards relevant to OXCs including GMPLS.
Design of multi-port OC-48 PHY daughter card. The card served as the front end to an upper-layer switch, and was compliant to GR-253-CORE SR-1.
Created portfolio of system testing scripts in TCL/Expect. The scripts were used to test system configuration and connection setup/teardown as well as QoS performance per RFC-2544.
Lead Engineer.
Technical lead in charge of developing a short-reach OC-192 (SR-2 per GR-1377-CORE) optical line card used in a carrier-class terabit router/switch.
Technical Staff Member. While at IBM Research, I was responsible for development of novel lasers optimized for WDM transmission systems. After sale of group from IBM to Tellabs (Jan. 1997) I became involved in the following engineering activities:
Designed, constructed, documented, and ran the WDM transmission testbed. The testbed was used for both component and transmission link performance testing. The Tellabs WDM system supported both opaque add/drops, as well as transparent pass-through notes.
Involved (as an alpha customer) in development of an early Nortel DM laser with on-board wavelength locker. I designed a test card to support the on-board locker and simultaneously transmit 2.5 Gbps data. I performed physical and system-level transmission characterization (e.g. wavelength stability, optical spectrum, eye diagrams, system Q [BER]). My results were documented and shared with scientists at Tellabs and Nortel.
Contributing team member working on architecture, design, and bring-up of OC-48 OEO card.
Performed optical component evaluation and specification. Wrote component specifications and documentation based upon experimental results.
The system designed by my group eventually became the Tellabs 7100 Optical Transport System.
Senior Scientist, Optical Communications Department.
