Experience
Joule Unlimited (biofuels startup) Bedford and Cambridge, MA
Principal Engineer 2011-2015
 Recruited by the Engineering Senior VP, a former colleague from a previous employer
 Safely led project on simulated flue gas with SO2, NO2, and CO, proving our cells can use impure CO2
 Modeled increased productivity with light management; model was verified experimentally in the field
 Company resource for light measurement, thermal imaging, and ultrasonic flow measurement
 Covered Bedford-based photobioreactors on weekend rotation; modified circuitry for power outages
 Traveled to Pilot (TX) and Demo (NM) plants for my experiments and in support of others' testing
 Earned Joule awards for contributions to an ethanol production proof point in the field and for working
on and improving processes and data analysis for screening and enrichment in Biology
TEL Epion, Inc. (a division of Tokyo Electron, Ltd.) Billerica, MA
Principal Scientist and Engineer 2007-2011
 Recruited by former supervisor at previous employer
 Only full-time, practicing physicist on the team; reported to the TEI VP of Engineering
 Consulted with management, marketing, and engineering provide actionable information for design and
for presentations to existing and potential customers
˔ Measured and reduced contamination for proof-of-concept, prototype, and demo-ready systems
˔ Developed Matlab simulations to answer questions about deep trench formation from TEL’s US
technology group at the Albany Nanotechnology Center
˔ Analyzed and modeled data to determine cluster size distributions, resulting in the first relevant
information for marketing and executive presentations in years
Axcelis Technologies (formerly part of Eaton Corporation) Beverly, MA
Senior Systems Engineer and Principal Scientist 2000-2007
 Elected 2006 Distinguished Technologist for improvements to high current implantation equipment and
process, many of which were implemented on production equipment worldwide
˔ Led successful technical effort to improve yield and parametrics by measuring and controlling ion
beam angle; designed and tested prototype hardware and software, and introduced it to the field

2. ˔ Developed and verified mass analysis models to predict beam tuning; increased throughput and
reduced species cross-contamination at European and Asian customer sites
˔ Pioneered arsenic dimers (As2
+
) for higher throughput and equivalent process performance to
increase competitiveness of Eaton and Axcelis product specifications
 Characterized the GSDIII/LED, GSD/Ultra upgrade, and Optima HD implanters
˔ Technology lead on Core Team that transferred GSDIII/LED from our Japanese joint venture (SEN)
˔ GSD/Ultra series won multiple sales of more than USD 20MM vs. the market leader
˔ Specifically requested by a US customer to qualify first Ultra tools (sales at this site, USD 10MM)
Eaton Corporation Beverly, MA
Equipment Test Engineer and Senior Systems Engineer (Demo lab) 1994-2000
 Performed and reported on process and equipment demos of GSD200 series high current implanters
˔ Resulted in dozens of USD ~1.5MM sales to customers in Asia, Europe, and North America
 Resolved urgent dosimetry, charging, and equipment issues in-house and at customer sites worldwide
˔ Visited 12 customer sites, usually when interaction with the customer had become critical and
required handling of potentially volatile situations
˔ Major contributor to new charge control technology; traveled to prove its efficacy to customers in
Taiwan and Singapore, securing an estimated USD 30MM in equipment sales
˔ Solved dosimetry, charging, and operational issues with the first GSD-200E2
160kV equipment at a
new customer. The customer accepted and later advocated this model, rather than returning it.
AT&T Bell Laboratories Murray Hill, NJ
Member of Technical Staff-I in a silicon molecular beam epitaxy research lab 1989-1993
 Technical contributor to research of SiGe multilayers, ultra-smooth Si surfaces, and Si/SiO2 interfaces
 Designed and implemented unique PID temperature controlled, electron beam heated dopant source
Virginia Commonwealth University, and Custom Synthesis, Inc. Richmond, VA
