I have 35 years of experience, and specialize in the field of design research with specific knowledge in the areas of human factors, human-computer interaction and product design. I have published on such topics as product development, human-computer interaction and research methodology. I have testified on interactive television, user interface design and remote control devices. In my relatively short time as an expert witness, I have earned a reputation for unparalleled expertise in product design, particularly the user interface design aspects of screen-based user interfaces (computers, mobile devices and televisions) as well as physical devices, such as remote control and mobile devices. It has been said by my clients that I am personable, a hard worker and very focused and that I have actual industry, as well as academic experience, both of which combine to imbue my testimony with a high degree of credibility.
