Expertise - Key Words: Expertise in electronic control and communication systems. Serving the legal forum with consulting and testimony.

Curriculum Vitae

Technical Background

My technical background includes study and hands-on experience in building and maintaining electrical and electronic systems such as: remote control devices, security and alarm systems, wireless microphones, signal distribution panels, carrier-current transmitters, sound and public address systems, computer and data processing equipment, radio and television equipment, automotive electronics, tape recorders, radar and lidar, cellular telephones, and video surveillance devices.

Forensic Experience

I have contributed to a variety of legal matters based on electrical and electronic technology including: electric shock, lightning damage, defective electrical wiring, surveillance monitoring, disputed recording tapes, acoustical audibility, radio broadcasting interference, traffic radar, voice recognition, police laser radar, pocket paging systems, electronic circuits, accident reconstruction, telephone communication, and automobile engine electronic control. (See list below.)

I provide site inspections, field measurements, laboratory analyses, test reports, and technical findings, with thorough documentation of results and opinions, for civil, criminal, and patent cases. I assemble crucial demonstrative evidence in the form of photographs, tape playbacks, and equipment presentations, and I am an experienced expert witness in the legal forum.

Communication Skills

The best technical and analytic skills are not serviceable without effective professional communications. As an experienced technical presenter in high-technology industry, I have also tried to develop the ability to articulate complex scientific constructs and convey their essence for lawyers, judges, and juries. Many cases have settled without the need for a trial, as a result of my analyses highlighting the technical nexus and critical characteristics of an incident.

Industry Qualifications

For cases that get to the courtroom I have invariably qualified as an expert in the physics or electronics applicable to the matter. This is due in part to thirty years of full-time experience in the defense and aerospace industry at these firms:

Bendix Radio Division, Baltimore MD

Sperry Gyroscope Company, Great Neck NY

Pennsylvania Research Associates, Philadelphia PA

RCA Corporation, Aerospace & Defense Group, Moorestown NJ

Computer Sciences Corporation, Integrated Systems Division, Moorestown NJ,

where I studied the capabilities and limitations of advanced systems for detection, tracking, communication, control, radar, sonar, and electronic countermeasures.

I have formulated and evaluated new concepts on acoustic and electronic warfare, for detection and tracking of moving vehicles, for defense against missiles and torpedoes, and on computer-generated imagery. I am credited with 20 publications in the open professional technical literature (See list below.), and I have written several hundred formal technical reports bearing government security or proprietary restrictions on their distribution.

Documentation of Credentials

Bachelor of Electrical Engineering, University of Florida, Gainesville FL

Master of Science in Applied Science, Adelphi University, Long Island NY

Master of Business Administration, Monmouth University, Long Branch NJ

Senior Member: Institute of Electrical and Electronics Engineers

Fellow: American College of Forensic Examiners

Diplomate: American Board of Forensic Engineering and Technology

Rate Structure

I charge a uniform hourly rate, which includes all overhead, for consultation, field examination, technical analysis, report preparation, deposition, or attendance at trial. This fee applies to all authorized work on a case. Billing begins only upon work authorization. Out-of-pocket expenses are billed at actual cost. (However, expert referral services may impose their own rate structures.) For out-of-town travel I customarily charge for only half the time actually spent in transit.

Operating Principles

As with any court expert, my duty is to render and to support my objective scientific opinion on the matter at hand. In particular I can serve as your technical consultant and scientific interface with other narrower specialists who speak only in academic jargon. I can help you debunk the unfounded or pseudoscientific claims of your adversary. I invite litigants and factfinders to contact me to discuss assistance in resolving your case dealing with physics or electronics.

Office Location

My office is just east of center city Philadelphia. I can easily travel as necessary to work at your location or at the site of an incident to be investigated.
