Summary of Expertise:

Listed with other top experts in: 

Expert has studied how police collect eyewitness identification evidence for over 30 years. His work includes developing and testing alternative identification procedures that have been widely adopted by police (e.g., sequential lineups). More specifically, he has conducted and published research on the following topics: finding suspects using descriptions of criminals, facial composites, and mug shots; identification of suspects using mug shots, showups, and lineups; factors that bias identification procedures (increase error rates); "postdicting" identification accuracy (factors that suggest the witness is more versus less likely to be correct); and belief (credibility) of identification evidence in court. He has taught or trained police officers, prosecutors, defense attorneys, and judges. He has consulted about eyewitness identification issues on three continents.
