Forensic Analysis

fire debris at crime scene

The Forensic Analysis research area explores the chemical and biological analytical aspects of forensic science including evidence recovery methods, extraction of analytes from difficult and unusual matrices and the development and improvement of analytical methods for forensic samples.

This includes chemical analysis research on drug analysis, analysis of New Psychoactive Substances (NPS), drug facilitated sexual assault, fire investigation, fire debris recovery and analysis of ignitable liquid residues, analysis of drugs and pharmaceuticals in the environment, analysis of pharmaceuticals in unusual matrices for wildlife conservation, analysis of drugs in unusual matrices in relation to forensic toxicology, work placed drug testing, analytical methods for diagnostic tools and biomarkers, forensic toxicology, method development and validation, detection and quantification of cocaine on new polymer banknotes, ageing of fingermarks and detection of body fluids under paint using vibrational spectroscopy techniques.

The biological analysis research includes body fluid identification using RNA analysis, body fluid identification using DNA methylation, DNA and RNA analysis from fingermarks treated with VMD and other fingermark enhancement methods, analysis of DNA and RNA from biological fluids and trace evidence.

The Forensic Analysis research area is part of the Forensic & Investigative Sciences Research Group.

We offer our Forensic & Investigative Sciences PhD. We've also identified a range of innovative research project opportunities for postgraduate researchers.

Research and outreach activities in Nepal

Dr Lata Gautam in Forensic and Investigative Sciences, School of Life Sciences has just returned from Nepal after a series of outreach events.

Following on from last year’s capacity building training in Nepal funded by the Royal Society of Chemistry, and a national workshop on Drug Facilitated Sexual Assault (DFSA) investigation funded by the Research and Innovation Development Office (RIDO), Dr Lata Gautam organised a series of outreach events in Nepal during the months of April, July and August in 2019.

The activities, funded by our Faculty of Science and Engineering and School of Life Science, mainly consisted of public awareness and outreach events as well as a multi-stakeholder consultation workshop on sexual assault and DFSA, organised at the national, sub-national and community levels in the country.

A number of in-country partners in Nepal supported these activities, including: UNESCO Schools’ Collaboration Council, The Biotechnology Society of Nepal, Neuro Nepal Foundation, Science Teachers’ Association in Nepal, Manohar Secondary School Resource Centre, National Forensic Science Laboratory, Central Police Forensic Science Laboratory and the National Examination Board of Nepal.

For school level activities, a number of awareness programmes were carried out in seventeen different schools over three provinces and six districts of Nepal. The multi-stakeholder engagement meeting in Kathmandu included many relevant stakeholders including the Honourable Minister of Education, Science and Technology, Secretary of Nepal Bar Association (legal body), Judge at the Kathmandu District Court, forensic scientists, crime scene officers, lawyers, medical students, medical professionals, researchers, and a number of civil society and non-state actors in Nepal.

The meetings were made up of presentations and innovative forms of public communications such as poetry, drama and mind-maps. These activities were followed up with a number of media coverages in Nepal, from newspaper stories and articles to TV coverage on Prime Time TV and a one-hour discussion on the Image Channel.

A community engagement and awareness event on DFSA was also organised in Kathmandu Metropolitan City, New Baneshwore, through the Community-Police Partnership programme and other non-governmental organisations. And a number of one-to-one meetings were held with key policy makers and stakeholders where key findings from Lata’s work on DFSA in Nepal was presented to the Minister of Education, Science and Technology, Nepal Police and forensic professionals in the country.

Dr Lorna Nisbet to be published in 'forensic toxicology bible'

Dr Lorna Nisbet has been asked to submit a paper to be included in the new edition of Disposition of Toxic Drugs and Chemicals in Man.

Lorna, from our School of Life Sciences, has been asked to submit her paper ‘Gas chromatography-mass spectrometry method for the quantitative identification of 23 new psychoactive substances in blood and urine’, that appeared this month in the Journal of Analytical Toxicology, to be included in the new edition of the Disposition of Toxic Drugs and Chemicals in Man.

This reference book is typically referred to as the ‘forensic toxicology bible’ and routinely relied upon when interpreting results and presenting information for court.

Funding awarded to Forensic Science

Dr Lorna Nisbet has been awarded £4K by the Royal Society of Chemistry to carry out in-vitro metabolism studies using the new psychoactive substance mexedrone.

Mexedrone is a synthetic cathinone with approximately 2/3rd the potency of mephedrone. Although this compound is currently banned by the New Psychoactive Substances Act seizures and presentations at emergency rooms are still occurring. Identification of the drug in biological materials is challenging as the degree to which it is metabolised within the body is currently unknown.

Lorna hopes this funding will allow her to collect data which can then be used when applying for larger grants. This funding will also allow Lorna to build upon the research she presented in Boca Raton.
