This year marks my 25th year working at Harvard University, working in an applied physics laboratory environment.  I spent 18 of those years at the School of Engineering and Applied Sciences (SEAS) as a manager and engineer and ran a 1.7 MV Tandem Ion Accelerator; became a local expert in the application of accelerator based elemental and materials analysis techniques, such as Rutherford Backscattering Spectroscopy (RBS), Ion Channeling, Forward Recoil Detection (FRD) and Particle Induced X-ray Emission (PIXE) spectroscopy. I also developed a working knowledge of SEM, and Focused Ion Beam (FIB) instruments.

After that. I spent 4 years working for the Harvard Nanopore Group and helped to develop an Ice Lithography instrument which utilized a state of the art FE-SEM (Field Emmission Scanning Electron Microscope), beam writing instrumentation and metal deposition technology.  After that I came to the Rowland Institute to help out with specific projects relating to the Junior Fellows program and to help out with the Freshman Seminar.

Along the way, I developed other skills including most aspects of vacuum technology; electronic troubleshooting to the component level: analog and digital; experience with high voltage; electrical wiring. Experienced in the use, handling and disposal of hazardous chemicals. mechanical design using CAD; complete machine shop skills including use of the lathe, milling machine, welding and silver soldering.
