My consulting activities provide me an opportunity to apply my research and interests in visual science and human factors to the legal community. I have been conducting research in university settings since 1988 and have over 20 publications and 55 conference presentations and invited addresses.
My expert opinions center on visual perception and human factors issues such as, but not limited to, conspicuity, lighting conditions, perception-reaction time, expectation and attention. My plaintiff-defense case distribution percentage is approximately 50%-50%, and includes both civil and criminal cases involving driving, traffic, pedestrian, residential, trip & fall, and boating/maritime matters. I have over 15 years of consulting experience and have worked on cases in Alabama, California, Delaware, Florida, Georgia, Indiana, Kansas, Louisiana, Nevada, New Jersey, North Carolina, Ohio, Oklahoma, Pennsylvania, South Carolina, Texas, and Virginia.
In all my cases, I endeavor to conduct my consulting activities with the utmost honesty and professional excellence.
