Over the last two decades, I have been developing forensic ecology, botany, and palynology. These areas of study have proved to be invaluable for the provision of intelligence and probative evidence. I am an experienced expert witness and presented evidence, under cross examination, in Crown and High Courts, Magistrate Courts, and Coroners’ Inquests in England, Wales, Scotland, Northern Ireland, and Eire. I have worked with every police force in the UK and Ireland and am concerned with providing guidelines and protocols for best practice in various branches of forensic ecology for practitioners, as well as for the police at crime scenes, and pathologists in the mortuary. I feel it is important for every aspect of work to be of the highest standard, and aim to continue demonstrating the power of botany, zoology, and soil science in forensic science.

Research interests

(1) Environmental reconstruction of ancient environments through analysis of palynological sequences in sediments, buried soils, and riverine deposits (palaeoecology and archaeology).

(2) Taphonomic processes affecting palynological surface ground patterning

(3) Pollen taphonomy: factors affecting the distribution and frequency of palynomorphs on clothing, footwear, vehicles, and other items.

(4) Effects of palynological processing on the survival of fungal spores and other fungal structures that are useful in forensic examination

(5) Environmental reconstruction at the Happisburgh Early Palaeolithic site in Norfolk, using palynological analysis of submerged, marine peat deposits. This site has evidence of a human presence dating from 1,000,000 years before present. It is the earliest site of Homo brittanicus in Europe.

(6) Ecosystem approach to crime scene evaluation.

(7) Interdisciplinary contributions to trace evidence, estimation of post mortem interval, deposition times, and elimination of irrelevant locations.

(8) Evaluating testimony through physical evidence.

(9) Provision of intelligence from biological and physical particulates (trace evidence).
