PhD title: The Delta Study: A reanalysis of time series studies of air pollution and acute health effects

Supervisors:  Dr. Hubert Lam (UoB) and Dr. Richard Atkinson(SGUL)

This multidisciplinary study which is based on existing time series data and methods looks into the applicability and modelling of alternative exposure metrics for the study of acute health effects of air pollution in order to improve the prediction of the health effects due air pollution. These physiologically motivated new metrics are based on simple algebraic functions of daily absolute measures of exposure and finding an identifiable model will be one of the challenges in the course of the study. The project also benefits from excellent collaboration from within and outside the university as it is overseen by leading authorities in the area of environmental epidemiology from UoB, LSHTM, SGUL, and University of Hong Kong.

Nuredin graduated with Masters degree in 2007 from AAU while working for the Ethiopian statistical association and joined the London School of Hygiene & Tropical Medicine (LSHTM) in 2008/2009 to specialise in Medical Statistics through TEG/LSHTM’s scholarship award for African scientists. He then went to the MRC Laboratories, The Gambia unit as a postgraduate fellow in medical statistics for one year where he worked mainly on the analyses of laboratory data from various projects. After completing his fellowship in November 2010, Nuredin moved to Birmingham as doctoral researcher based at IOEM to work on the delta study. His research interest is generally in the application of statistical methodology in biomedical research. Particular application areas include environmental epidemiology and analysis of laboratory data.
