From Clues to Conclusions

Remember when getting a DNA fingerprint in the 1980s required a drop of blood the size of a 50p coin? Or when crime-scene training relied on tiny dioramas and doll’s houses back in the 1940s? Thankfully, forensic science has come a long way since then. Kat will take you on a journey through the latest breakthroughs in forensic DNA analysis. She will explain new methods for isolating and analysing single cells, allowing scientists to identify how many people contributed to a mixed sample right from the start, which appear in more than 60% of criminal cases including sexual offences. Kat will also demonstrate how we are using LEGO-based crime scenes and DNA-profiling activities to boost understanding and increase engagement with complex concepts. When the public—and the criminal justice system—better understand the possibilities of next-generation forensic science, we are better equipped to deliver justice for victims.

Kat is an Associate Professor of Forensic Science specialising in forensic genetics and entomology and has been teaching at the University of Portsmouth since 2008. Working with experts across the UK, her recent research is transforming how we obtain a DNA fingerprint from the smallest of samples, providing forensic intelligence and evidence. Kat encourages undergraduate students and postgraduate researchers to join her on these endeavours, as working at the forefront of impactful forensic science is challenging yet rewarding.

The ability to estimate the post-mortem interval (PMI), aka the time since death, can often be critically important in a death investigation, even in natural or non-suspicious cases. In addition, artificial intelligence (AI) and machine learning (ML) are rapidly evolving areas within computer science, and the fast development and efficiency of such technologies have led to their use being explored in a range of different disciplines.
However, there are many questions asked and conversations to be had about the use of AI/ML methodologies for both PMI estimation and within the broader forensic field. How do we balance innovation and accountability? How do we ensure that technology assists rather than replaces? Is there a place for these technologies in forensics and the wider criminal justice system?
Come and join me for a pint to explore some of these ideas further.

Money launderers don’t just move dodgy suitcases of cash – they hide inside perfectly normal trade. From Portsmouth’s port to global shipping lanes, this talk explores how criminals hide dirty money in ordinary trade – and why it matters to all of us. We’ll unpack trade-based money laundering in plain language: fake invoices, odd prices and phantom cargo. We’ll then look at how law enforcement, banks, shipping firms and other companies are expected to spot and stop suspicious activity but fail to do so effectively.
