I joined LSBU in 2019 after nearly 25 years in the scientific civil service, firstly at the Defence Evaluation and Research Agency where I worked on radar absorbing ‘stealth’ materials and smart composites for use in aircraft structures, and latterly at the Home Office Centre for Applied Science and Technology where I became Senior Technical Specialist, primarily working within the Fingerprint Research Group. I have a BSc and PhD in Materials Science, both from the University of Bath, and am a Fellow of the Chartered Society of Forensic Sciences and a Member of the Institute of Materials Minerals and Mining.
My main research interests are in the interactions that can occur between the environment, the surface and different types of trace evidence that may be deposited on it, bringing together my background in materials science and my more recent experience in forensic science. These interactions are critical in understanding whether trace evidence is likely to survive the conditions at a crime scene and subsequent environmental exposure, and better understanding the changes in chemical and physical properties that occur may lead to improved ways of recovering trace evidence exposed to extreme environments. I also have an interest in the use of advanced imaging techniques for the location and imaging of trace evidence.
I am an invited member of the International Fingerprint Research group and through collaborative networks formed from that membership have co-authored over 50 forensic science-related publications in peer-reviewed journals, am one of the principal authors of the world recognised Home Office Fingermark Visualisation Manual, and recently authored the text book ‘Fingerprint Development Techniques – Theory and Application’ published in 2018. I also act as a Forensic Advisor to the Defence Science & Technology Laboratory, and as a Technical Assessor for fingerprint laboratories for the UK Accreditation Service.

Prizes, awards, and accolades
Innovator of the Year (Jul 2017)
Defence Science & Technology Laboratory (Dstl)
This was an award made for collaborative work between the Home Office CAST (where I was employed at the time), Dstl and Loughborough University in taking a novel chemical technique from a laboratory concept towards a commercially available piece of equipment for development of fingermarks on high priority surfaces (fired cartridge cases, knives). This is now available as the Foster + Freeman RECOVER process
P W Allen Prize (Nov 2015)
Chartered Society for Forensic Science
The PW Allen award is presented to the most meritorious paper published in Science & Justice each year.
The PW Allen Award is given in memory of Phillip W Allen. Phillip W Allen was Vice President of the Society from 1976-1978. Phillip was instrumental in bringing to market the first micro cameras. These were first used by the Metropolitan Police in the Spaghetti House Seige in the late 70's. The company continues to manufacture and sell a range of anti-terrorism equipment. They include explosive ordnance disposal (EOD) bomb search and detection; bomb technician tools; and Electronic Counter Measures (ECM) equipment used to stop remote detonation of bombs.
Awarded for the co-authored paper: S Cadd, M Islam, P Manson, S Bleay: Fingerprint composition and aging: A literature review, Science & Justice, 2015
Evidence to public body
Nov 2009
Engaged to provide expert advice on fingermark enhancement to the Inquiry team and presentation of oral evidence on findings to the Fingerprint Inquiry, Scotland
The Fingerprint Inquiry was a public inquiry set up by Scottish Government ministers under the Inquiries Act 2005 to look at the steps which were taken to identify and verify the fingerprints associated with the case of HM Advocate v McKie in 1999. The Inquiry was to determine the consequences of steps taken, report on findings of fact and make recommendations
