Dr Gordon Hay joined the Public Health Institute in November 2012 as a Reader. Prior to that appointment he was researcher at the Centre for Drug Misuse Research at the University of Glasgow. His research has focused on the application of epidemiological and statistical methodologies within the area of drug or alcohol use and in his new position he aims to further develop this work more into other areas of public health. Gordon’s main research has been developing and applying statistical methods to estimate the number of people who use drugs such as heroin or crack cocaine. Traditional surveys are often inappropriate therefore other approaches, such as the capture-recapture method, have been developed. He has carried out such work at the local, national and international level and has led a programme of research studies that have produced the annual estimates of opiate / crack cocaine use in England. He is the UK Scientific Expert to the EMCDDA for their Problem Drug Use Key Indicator and has carried out a range of projects for the EMCDDA and other international organisations such as the UNODC in various countries including the Baltic States and Turkey. Gordon has collaborated with qualitative and quantitative colleagues in a number of studies, including research that quantified and sought to understand benefit uptake by drug or alcohol users for the DWP. He has been involved in a number of large-scale evaluations, such a multi-method evaluation of the UK Government funded programme of drugs prevention projects within Health Action Zones. He also led studies looking at the social and economic costs of drug use and the likely size of the Scottish drugs market. Gordon’s PhD at the University of Strathclyde used mathematical models to examine the spread of HIV amongst people who inject drugs and he still maintains an interest in blood-borne virus epidemiology and drug-related mortality and has continued to publish in these areas.
