Karen joined the Public Health Institute (PHI; formerly Centre for Public Health) in 2006. She is part of the Public Health Intelligence Unit at PHI and has worked with various monitoring and surveillance systems.
When Karen began her public health career at PHI she joined the Criminal Justice Team as a Data Administrator for the Drug Interventions Programme (DIP). In 2009, Karen became a Prisons Data Quality Analyst for the team before spending a brief period of time with the North West Public Health Observatory. Karen returned to working with prisons’ data and had a leading role in the implementation of the National Drug Treatment Monitoring System (NDTMS) in prisons.
When the NDTMS team moved over to Public Health England (now Office for Health Improvement and Disparities) in 2013, Karen chose to stay with PHI and joined the Trauma and Injury Intelligence Group (TIIG) as a Public Health Researcher/Analyst. In 2014 she became the TIIG Project Lead, managing the intentional and unintentional injury data collected routinely via the TIIG monitoring system.
In 2016 when Karen returned to work following maternity leave, she became the Criminal Justice Project Lead, responsible for the monitoring of DIP and criminal justice interventions delivered to offenders who use drugs and/or alcohol across Merseyside. As well as leading on the criminal justice monitoring system, Karen continues to be part of TIIG as the project lead for the development of a data hub to support the West Yorkshire Violence Reduction Unit.
Karen also supervises student dissertations on the BSc Environmental Health and Public Health courses and the MSc Public Health programmes.
