Drew is the Principal Health Physicist at Forensic and Scientific Services Radiation and Nuclear Science unit. His tasks span a broad base of radiation protection consultancy services ranging from dosimetry advice to project management for complex environmental and occupational radiological impact assessments.  As leader of the Radiation and Nuclear Science unit, Drew strives to provide services tailored to client needs and consistent with best practice radiation protection governance and culture.

Drew has an interest in environmental applications of Health Physics. In particular, the characterisation of Naturally Occurring Radioactive Material (NORM) under circumstances where there is a juncture between the public, environment and sources of NORM.
