PROFESSIONAL EXPERIENCE:
MEDICAL AND INDUSTRIAL ULTRASOUND DESIGNER/CONSULTANT
(2007 – Present)
Systems designer specializing in medical and industrial ultrasound including
therapeutic and diagnostic ultrasound, NDT/NDE, and ultrasound
measurement and control applications. Provide technical advice, analysis,
and design support to academic researchers and the ultrasound industry.
Experienced in physical acoustics, RF/analog circuit design,
digital hardware design, custom prototype construction, and embedded software
applications.
SPECTRASONICS IMAGING INC., Wayne, PA (November 1997
– June 2007)
Director of Research and Development, founding member
of a team which developed several high-powered therapeutic ultrasound
systems. Investigated the use of ultrasound therapy in cardiac applications.
Designed hardware to acquire digitized RF data from a commercial medical
imaging engine. Wrote and administered a phase II SBIR grant to develop
an ultrasonic prostate cancer detection/biopsy guidance system. Detection
algorithm runs on a SHARC processor network embedded
in a PC platform, DSP code was written in C++, and user
interface was created using Visual C++/MFC. System was
interfaced with a commercial ultrasonic imager and entered clinical trials
in October 2000. Applied for 2 patents related to this technology.
ULTRAFAST INC., Malvern, PA (March 1993 - November 1997)
Senior Staff Scientist in charge of ultrasonics research
and analog circuit development. Designed the thin film piezoelectric transducer
and HF analog front-end electronics used in an ultrasonic load-measurement
system. Wrote firmware and user interface software in Borland C++. Modeled
the ultrasonic transducer using PIEZOCAD and developed a model of acoustic
propagation within a fastener for use in house. Applied for 4 PATENTS
related to enhancement of the technology. The detection and excitation
electronics were designed to interface with automated tightening equipment
and were miniaturized and optimized for low power operation.
DREXEL UNIVERSITY, Philadelphia, PA (Oct. 1987 - Oct.
1992)
Research Assistant working in the field of Biomedical Ultrasound. Completed
a project to develop and test a model of ultrasonic wave propagation in
biological tissue-like media. Project was funded by a two year NSF award.
Ph.D. thesis focused on including the effects of nonlinear acoustic
phenomena into the propagation model.
