David received his Ph.D. in Psychology from Cambridge University and has been a part of the study since the beginning as a co-applicant to OJJDP in 1986. He has published 25 books, over 360 papers, and his research interests are in risk factors for offending, and development of offending at different ages. David is currently working on a third book on the study and has recently completed two papers: one comparing self-reported and official offending and the other comparing homicide offenders and victims.
