My involvement in the lighting industry started in 1995. In this time I have been immersed myself in different facets of the industry including indoor and outdoor lighting, safety and security, lighting and human health, and lighting standards. Since 1999 I have been involved with several standard writing committees within the Illuminating Engineering Society of North America producing over six standard documents. Teaching has been a part of my career since I began in the industry in 1995, teaching to diverse groups from high school students to seasoned lighting professionals. Having a diverse background has allowed me to produce lighting designs, verify compliance, calculations, and photometric and equipment verification in the office. However I have also had field experience with commissioning, field survey and verification, and troubleshooting of field designs and equipment issues. I am available nationwide for your witness needs.

Electronics, Engineering - Integrated Circuits (ICs), Patent Infringement, Mixed-Signal, Analog, Radio Frequency (RF), Signal-Processing, Analog-to-Digital (A/D), Digital-to-Analog (D/A), Control Systems, Semiconductor, System on Chip, SOC

My sub-specialty within the broad category of electrical engineering is with integrated circuits (or complete systems) used for signal-processing, which • Detect signals from a sensor (e.g. antenna, microphone etc. • Amplify, filter, then convert to digital • Process further in the digital domain • Convert the result back to the analog domain for further processing, and/or • Deliver the final output to an actuator (e.g. antenna, speaker, video display, heater control-switch etc.). Examples of these systems are • Mobile and cell phones • Recording and retrieving systems for disk drives or tape • Radio transmitters/receivers and their building blocks such as low noise amplifiers, filters, automatic gain control and frequency mixers (down-converters, up-converters) • Audio amplifiers • Audio recording/reproduction systems • Heat, ventilation and air conditioning controllers • Data transmitting/receiving systems such as serializer/de-serializers (SERDES)
