Forensic Examination of Signatures CoverI was pleased be a co-contributor for Dr. Linton A. Mohammed’s latest textbook, Forensic Examination of Signatures.  Other contributors, along with Dr. Mohammed, were Lloyd Cunningham, William Flynn, and Kathleen Nicolaides, with the Foreword by the esteemed Professor David Kaye.  The text was published June 6, 2019 by Elsevier’s Academic Press (ISBN:  978-0-12-813029-2,

The book focuses on the forensic examination and evaluation of signatures which is one of the most difficult areas of Forensic Document Examination.  My contribution was Chapter 11 entitled “Conclusions, Reporting and Testimony”, co-written with Dr. Mohammed.

The main topics include complexity, signature styles, the differentiation of genuine, disguised, and simulated (forged) signatures, as well as the effects of common limitations affecting such examinations such as non-original documents, the influence of age, illness or writing constraints on signature examination.   Related topics include cognitive biases, methods to reduce or mitigate those biases, and research on validity and reliability of signature examinations.  All in all, I am very happy to have been involved in this initiative.
