Having recently submitted his doctoral thesis at Northumbria University, Mark retired from policing in September 2023 following a 30-year career, serving predominantly as a detective across all ranks through to Detective Chief Inspector.
A long-standing passion for investigation culminated in over ten years as a nationally accredited PIP3 Senior Investigating Officer (SIO), leading complex homicide investigations and overseeing the safe management and resolution of crimes in action, including kidnap and abduction offences.
Alongside this operational experience, Mark developed a growing interest in how academic research can inform and enhance real-world policing practice. This commitment to bridging theory and practice led to the award of a Master of Science (MSc) with Distinction in Criminal Investigation from Teesside University in October 2022.
His doctoral research, supervised within Northumbria University’s Business School, examines the impact of occupational stressors, personal resources, and passion for work on well-being outcomes among Senior Investigating Officers. His submitted thesis, Background Noise – Stress appraisal and the influence of resources on well-being in SIOs, integrates extensive professional experience with academic inquiry and is intended to contribute to national debate, policy and practice concerning the well-being of SIOs across UK policing.
