I am a partner with my wife Lyn, in a firm called HFC. We provide consulting and services to legal, business and governmental clients.  We offer legal expertise in the three areas of (a) evaluation of eyewitness testimony and Identification; (b) memory accuracy and recovery: and (c) human factors issues of safety, warnings, human error and accident evaluation, equipment design, and training adequacy.  Our services include consultation with the client, review of existing research collection of new research if required, and where needed, expert testimony in court.  I have offered expert testimony on factors that affect the accurate encoding of visual information (for example, how accurately can someone with normal vision perceive an event at a given distance under given light levels?  What is the likelihood of error in "recognizing" a person later if the event occurred within a specified time frame, with a weapon in evidence?).  I have also provided expert testimony on factors that affect the accuracy of retrieval of previously perceived events ( for example, what changes in memory may occur as a result of the passage of time, rehearsal of testimony.   Structure of questions, or introduction of photo or real lineups? ) I have taught seminars for lawyers and for trial judges to assist them in evaluating the criteria governing The challenging of memorial and perceptual testimony in the courtroom. We assist clients representing either defendant's or plaintiffs.
