Staff Profile

Dr Daniel Chalk

Senior Research Fellow

Kath Maguire

I work within PenCHORD – the Operational Research division of PenARC. There are two main aspects to my work. First, I lead projects that apply operational research techniques to improve healthcare services. I’ve carried out a broad range of projects for primary care and commissioners across the region, including determining the potential impact of extended diabetic retinopathy screening intervals, forecasting future levels of demand for ophthalmology services, and assessing the practical feasibility of potential changes to the fractured neck of femur pathway. I have experience of a broad range of operational techniques, such as agent-based simulation, discrete event simulation, systems dynamics modelling, Markov modelling and forecasting methods. Second, I work with the Peninsula Health Technology Commissioning Group (PHTCG) to develop models that assess the cost-effectiveness of proposed interventions, such as new drug therapies that have not been assessed by the National Institute for Health and Care Excellence (NICE).
