Dr John Douse

John Douse is our exclusively recommended Forensic Science Services expert in England on the Advisory Excellence website. If you need assistance in this area, please contact John directly using the contact details above.

We are a unique niche provider of Forensic Services in the UK, undertaking a limited number of highly specialist cases each year (circa 25), devoting the time needed to fully investigate each case, and including as thorough as possible analysis, consideration, and integration of both the forensic and also the circumstantial evidence.

We take an intense pride, during such a time of uncertainty in the adequate provision of forensic services in the UK, in ensuring that all aspects of each case are fully investigated; even if this requires us to carry out additional pro bono investigations when private or public funds are unable to fully meet the demands of such a painstaking approach (not infrequently 100 hours of requested work having to be “written off” due to the LAA or private individuals simply not being able to provide finance).

Our ability to lead in the interpretation of forensic evidence (continuously innovating and introducing new and highly effective avenues of approach, analysis, and investigation) is especially appreciated by Defence Lawyers and Barristers, Insurance Companies, Prominent International Businesses, and also Private Individuals; who are otherwise faced with the alternative access to only the briefest consideration of their cases by the cheapest, poorly qualified, alternatives.

Our innovations in the interpretation of forensic evidence arise as a result of a varied and prolonged, often pioneering forensic experience (34 years as a Forensic Scientist and 41 years total scientific experience).

This experience includes a, perhaps, unusual combination of forensic casework experience augmented by having pioneered, researched and developed the basis of many of the major forensic trace analytical and quality control techniques in use today worldwide. Our experience also includes, critically, the pioneering first introduction of the techniques and protocols of clean room technology and quality control (1990 at the Forensic Explosives Laboratory) now the mainstay of Forensic Quality Control worldwide.

Even more unusually, in the field of explosives, practical training was gained (and also the ability to instruct others in) the techniques of Special Forces Demolitions, involving the trialling, testing and deploying of improvised and military, explosive and incendiary, mixtures and devices, often culled from official and unofficial instruction manuals.

As a result of this varied experience we operate highly effectively in the fields of explosives (all areas), toxicology (including Insulin, Ricin, thallium, and CW agents), drugs (chemistry, synthesis, purity), DNA, firearms residues, sexual offences, (significance of traces), and a wide range of other applications in forensic chemistry (laboratories, counterfeits etc).

Our approaches, not infrequently, result in even the most experienced, opposition experts having to concur with the defence opinion, due to the presentation of the most up to date research results, (some of which may just have been published only days before the completion of the defence report, as in a firearms residue case in 2018) (presence of tin in shotgun residue) and also the avoidance of the use of subjective opinion.

The sheer amount of time that we can devote to each case is often the game changer in many cases, and not infrequently allows us to prevail, due simply to our ability to detect and observe facets of evidence that have simply been overlooked (eg intensive inspection of training videos, augmented by our expertise in recognising the critical technical details, eg in a case involving preparation of ricin).

Multi-Disciplinary Forensic Experience is also one of the mainstays of our expertise, and arises as a result of having pioneered and introduced the basis of the analytical techniques and quality control methods still used worldwide in a variety of forensic areas.

The process of familiarisation and study of such areas has enabled us to provide new techniques, insights and approaches to the study of a variety of forensic expertise fields, the common thread being trace analysis combined with practical experience of the subjects being investigated.

The ability to carry out detailed and highly effective forensic investigations into a variety of the most complex cases, which may often initially appear to be outside of our core expertise, but which often turn out to have a basis in chemistry (the basic and most fundamental specialism required for forensic work); coupled with referring critical aspects to other experts in a range of specialisms, as necessary, for them to focus on individual aspects of the case that might otherwise have remained unrevealed, is yet another game changer.

This experience has resulted in our involvement in the investigations into (among other cases) the Cyprus Poison Gas Extortion Case (Sarin and VX), Lybian Embassy Seige shootings, Lockerbie (Pan Am 103), Liquid Explosive Bomb Plot, London Glasgow Bombings, Wood Green Ricin Factory, Shakespeare Ellis “Drive-By” Shootings, Leeds Insulin Serial Killings, Roxel Rocket Motors UK v HSE, Private International Thallium Poisoning Case, etc.
