Contact Details


Independent inventor (14 issued US Patents) safety consultant/advisor.  Patent work concerns safety, sensors, LEDs and light guide technologies. A  peer-reviewed, globally published author with SPIE (The Society for Advancing Light Based Research).

• I am a US voting Delegate with The International Organization for Standardization (ISO). My stakeholder category is Industry and Commerce.

ISO/TC 58 - Gas cylinders
ISO/TC 58/SC 2 - Gas fittings
ISO/TC 58/SC 3 - Cylinder design
ISO/TC 58/SC 4 - Operational requirements for gas cylinders
ISO/TC 197 - Hydrogen technologies
ISO/TC 220 - Cryogenic vessels

The Hydrogen Technologies TAGs focus is on safety and performance for hydrogen vehicle pumps, stations, and the vehicle's receptacle. We develop and vote on the standards for all participating countries (P-Countries) which include China, India, Japan, Germany, Canada, France, Russia, and others.

• I am an ANSI-accredited U.S. expert with The International Organization for Standardization for hydrogen technologies.  My eight Working Groups (WGs) in the hydrogen technologies sector:

ISO/TC 197/WG 5 - Gaseous hydrogen land vehicle refueling connection devices
ISO/TC 197/WG 22 - Gaseous hydrogen fueling station hoses
ISO/TC 197/WG 23 - Gaseous hydrogen fueling station fittings
ISO/TC 197/WG 24 - Gaseous hydrogen fueling stations – general requirements
ISO/TC 197/WG 19 - Gaseous hydrogen fueling station dispensers – general requirements.
ISO/TC 58/ SC 3 /WG 17-Compressed natural gas cylinders  for road vehicles.
ISO/TC 58/ SC 3 /WG  27-Composite cylinders.
ISO/TC 58/ SC 3/WG  33- Refillable seamless stainless steel gas cylinders.

These WGs include hydrogen filling station components and their attachments to hydrogen powered vehicles, for all P-Countries.

• SAE Fuel Cell Interface Task Force
The Fuel Cell Standards Committee is responsible for establishing standards for vehicle fuel cell systems and their interfaces with the vehicle. Standards will cover the safety aspects of fuel cell systems in the vehicle, test procedures to establish the performance of the system/components, and interface requirements.

SAE J2600 applies to the design and testing of Compressed Hydrogen Surface Vehicle (CHSV) fueling connectors, nozzles, and receptacles. Connectors, nozzles, and receptacles must meet all SAE J2600 requirements and pass all SAE J2600 testing to be considered as SAE J2600 compliant. This document applies to devices which have Pressure Classes of H11, H25, H35, H50 or H70.

I am currently working to harmonize SAE J2600 with our ISO DIS 19880-1.

• SAE Technical Standards Task Force: Identifying Disabled User Issues for ADS-DVs. 

Level 4 and 5 Automated Driving System-Dedicated Vehicles (ADS-DVs that have no longitudinal/lateral controls) will eventually enable persons to travel at will who are otherwise unable to obtain a driver’s license for a conventional vehicle. Namely, persons with visual, physical, and/or cognitive impairments. The purpose of this task force is to gather and develop information on user specific issues to this non-driver population of ADS-DVs and their occupants. We will be looking at pick-up and drop-off issues for passengers in wheelchairs.  The task force will conduct a literature review, as well as consult with advocates for the blind, disabled, elderly and those with varying forms of ability. We will be producing an Information Report that summarizes potential user issues for this community. The task force will work closely with other SAE Committees (e.g., S&HF Steering Committee) on any work products created by this new task force. Inclusive design benefits all users not just those with varying degrees of ability.

For the stakeholder interviews, we are looking at four groups:

-People with disabilities, or varying forms of abilities.
-Advocates/occupational therapists and others in the space.
-Universal design, Inclusive design, and design for accessibility experts
-Government legislation or standards that are relevant or being introduced or discussed.

• I have twenty three years of safety, LED,  glass, fiber optics, and light guide technologies experience. My work concerns  illuminating surfaces and areas without bulbs, wires, or wired sensors in toxic, volatile or hostile environments. I have been on Working Groups for vented and non-vented gas equipment, and my work has many safety advances that can be applied to hydrogen technologies. In discussing safety with my TAG Chair, I identified vehicle lighting improvements that could make vehicles safer. I have also developed compact, premium LED daytime running lights with a global automotive lighting supplier. I hope to be on vehicle lighting TAGs administered by SAE because that would enhance my standards work with ISO. We need to make hydrogen stations and vehicles as safe and consumer friendly as possible, as they roll out.

• Member of the American Society of Mechanical Engineers (ASME).

• Member of the American Institute of Aeronautics and Astronautics (AIAA).

• I developed proprietary, high-power, compact LED automotive lighting with RipDark Ltd. in Shenzhen, China. RipDark is a cutting edge, engineer-based lighting company focused on advancing OEM, ODM and aftermarket LED automobile lighting. RipDark has filed fifty patent applications that focus on circuit performance, structure, and optical design.
