Dr Richard Rhodes (BA MSc PhD MCSFS) is a forensic consultant at J P French Associates. He has carried out research into the effects of aging on the voice in forensic contexts and assessing the strength of non-contemporaneous evidence statistically, and on cognitive bias in relation to forensic speech science. He is a member of the International Association for Forensic Phonetics and Acoustics (IAFPA) and sits on the executive committee as treasurer & membership secretary.
Dr Rhodes has worked on over five hundred and fifty forensic cases, including a range of high-profile and international proceedings. He works for both prosecution and defence and provides evidence as an expert witness in court in the areas of forensic speaker comparison, transcription and disputed utterance analysis, as well as other miscellaneous cases.
