Principal
Engineer,
Guilfoyle Inc., Belmont, MA, 1995 – 2004
Developed the
Bio-Ferrograph. An instrument an
instrument that captures cancer cells from blood
in an array for researchers. Cells
are captured on a glass substrate by processing a blood sample with magnetizing
solutions that preferentially bind to selected cell subpopulations and then
flowing the sample over a high gradient magnetic field.
The
Bio-Ferrograph captured cancer cells from volunteers’ blood at multiple sites,
and in proof of concept testing was capable of capturing 1 cell of the desired
type from a million background cells. Other areas where the Bio-Ferrograph excelled were tracking
bacterial movement through ground water, and the study of wear in artificial hip
joints.
Research & Development Engineer, Analyst Inc., Research Division, Belmont, MA 1991-1995
Developed a Light Extinction Measurement (LEM) for the amount of soot in a diesel engines lubricating oil. LEM was named the outstanding product for analysis and testing by Lubricant World in 1996. Soot in diesel lubricating oil in high concentrations is indicative of poor combustion, changes the Newtonian characteristics of the oil and contributes to excessive wear of the engine. LEM measures the amount of soot in diesel lubricating oil more accurately than any other method available, while only costing 7% of the next most accurate test.
Named as an inventor on US patent number 5,309,213
granted on the method used to measure soot in lubricating oil.
Supported the introduction of LEM to the marketplace by preparing and
presenting technical papers and training users.
Planned and conducted research projects.
Analyzed Ferrograms, made by passing a dilute oil sample over a high
gradient magnet field to precipitate particulate out of the oil onto a glass
substrate. Researched
methods of quantifying deposits on Ferrograms. Began research into methods of measuring soot in diesel
lubricating oil, a product line that was purchased in 1991 by Analysts Incorporated.
