Graham has extensive research interests, but his main research strand is Forensic RNA Analysis for body fluid identification and time-since-deposition of stains – managing a large team working in this field and has extensive publications and conference presentations in this field. He also has research interests in clothing damage analysis and bloodstain pattern analysis.
In his professional capacity, Graham also acts as a Consultant Forensic Biologist for a number of organisations; including a governmental organisation and an overseas company. He is also a reporting forensic scientist on an ad hoc basis for various organisations, providing reports for both the prosecution and the defence. He is extremely experienced in case work, having examined thousands of items for body fluids, DNA, BPA, and clothing damage. As a predominantly defence expert witness, he currently averages about 15-20 cases per year.
