Job description

Job summary

We are excited to announce that we are looking for a Research Associate in Biostatistics and Machine Learning to join a multi-disciplinary team. This is a great opportunity for a researcher with a strong statistical background to join our team of biostatisticians, epidemiologists and exposure scientists, to develop and apply statistical methods in for spatial and temporal structured data in the context of air pollution source characterisation and health effect evaluation.

This post is part of the project titled: “A statistical framework for the apportionment of particulate contaminants and their health effect determination“, funded by the Medical Research Council.

Duties and responsibilities

You will develop mixture models and other machine learning techniques to cluster particulate matter components into their sources and then link these sources to health outcomes. You will use a combination of simulations and real case studies throughout the project which will inform policy makers on the differential health impact of air pollution sources. The research team includes statisticians and exposure scientists from the MRC Centre for Environment and Health, as well as an epidemiologist at Public Health England, making the project closely linked to policy making.

Key responsibilities will include:

  • Developing mixture models in a Bayesian nonparametric framework that fit dependent data in time or space, explicitly including covariates that can affect the source specification (e.g. meteorology, geographical coordinates).
  • Extending the source apportionment model to evaluate the link between sources and health outcomes and predict the health risks under different scenarios of changes in the air contaminants.
  • Building simulation studies to assess the performance of the developed approach in comparison with state-of-the-art tools for source apportionment and for their health effect evaluation.

Essential requirements

You should have a thorough working knowledge of modern applied statistical techniques, including Bayesian hierarchical modelling and machine learning methods, preferably covering Bayesian nonparametric models. You should be highly proficient in R, preferably having used Rstan or R-nimble packages and hold a PhD in Statistics or a closely related quantitative discipline. A good understanding of environmental epidemiological concepts and techniques that apply to a wide range of study designs is essential for this role.

Further information

The post is offered on full time, fixed term basis for 36 months.

Candidates who have not yet been officially awarded their PhD will be appointed as a Research Assistant within the salary range £36,045 – £39,183 per annum.
