About

Successfully leading cross-disciplinary cross-department teams on projects from inception through execution to completion. Extensive mentoring / tutoring experience. Complete project engineering: from formulating the requirements through design / review process and testing / upgrading cycles on to testing / verification ultimately ending in install, customer training and maintenance. Applications Engineering: work with external/internal customers to ensure optimal performance of the subsystem; formulate and follow up paths to performance improvement. Test Engineering: designing, leading and implementing testing campaigns from R&D on to prototyping and to manufacturing. Manufacturing Engineering: subsystems/components sourcing, integration and applications testing. Development of in-line testing through integration process.

  • Final test and Service Engineer at Lyncean Technologies, Inc.
    Apr 2021 - Jun 2022 · 1 yr 3 mos

  • Physicist at Sigray, inc.
    Jun 2015 - Mar 2021 · 5 yrs 10 mos

    Physicist, Sigray INC., Concord, CA, June 2015-March 2021 Sigray designs and builds novel high brightness / high resolution X-Ray imaging tools. The aim is to provide customers with synchrotron-based capabilities with laboratory systems. As a physicist in the X-Ray source division I design, build, test, install and maintain high brightness X-Ray sources: Full cycle engineering: follow the project from formulating system requirements through mechanical, electric and vacuum designs; through testing campaigns on to customer delivery and support. Work with customers to formulate and define system requirements and benchmarks Design systems with mechanical engineers to meet the requirements (high vacuum - low outgassing, micron scale mechanical stability, thermal stability, high voltage, etc.) Design, implement and utilize high predictive value test protocols. Lead performance validation companigns, provide feedback to the upgrade and redesign cycles. Subsystems / components: define requirements, in-house vs. sourcing decisions Perform following as needed: vacuum tight welding, soldering, vacuum clean assembly, low outgassing surface finishing and preparation, high voltage surface finishing, component material analysis (spectroscopy and SEM), fluorescence and X-Ray component validation Model electron propagation, heat transfer, estimate X-Ray production and transport as needed Integrate, install, maintain and support systems remotely and on-site.
