RESEARCHER PROFILE: Postdoc / R2: PhD holders
RESEARCH FIELD(S)1: Computer science; Engineering; Mathematics; Medical science
MAIN SUB RESEARCH FIELD OR DISCIPLINES1: Machine Learning
JOB /OFFER DESCRIPTION
Hosting body: This position is based at the research unit SESSTIM (Health Economic and Social Sciences and Medical Information Processing) at the Timone Faculty of Medical and Paramedical Sciences, Marseille, France. SESSTIM works to produce excellent, multidisciplinary and interdisciplinary research in social sciences and public health that can lead to changes in the various fields of predictive, personalised, pre-emptive and participatory medicine. SESSTIM researchers develop, or are associated with, research projects that attempt to provide answers to current challenges facing society and its populations, and contribute to methodological developments and advances.
Main duties: The candidate will work in the multidisciplinary "Quantitative Methods and Medical Information Processing (QuanTIM)" team, comprising researchers in epidemiology and public health, statisticians, biostatisticians, computer scientists and data scientists. More specifically, he/she will be assigned to a project involving the application and development of Artificial Intelligence techniques to data from cancer registries. The aim of the work will be to develop or adapt a machine learning methodology in order to estimate excess mortality in the case of insufficiently stratified general population life tables.
Activities: As part of the MIRACLE project (Méthodologie et Intelligence aRtificielle pour lA recherche épidémiologique en CancéroLogiE sur bases de données), funded by the French Ligue contre le Cancer, the candidate will contribute to the valorisation of cancer databases, particularly the population-based ones. In this context, a key indicator is net survival that represents the survival that would be observed in a hypothetical world where people died only from the studied disease. Taking into account mortality due to other causes, derived from general population life tables stratified on certain variables, it enables comparisons between populations and trends to be studied. However, using insufficiently life tables leads to biased estimates of excess mortality. Different approaches have been considered and different models have been proposed to estimate excess cancer mortality for variables not directly observed in life tables. However, the models are based on assumptions that may be considered too strong given the needs and epidemiological questions. The candidate will familiarise him/herself with the various approaches and models already developed, and will then investigate the contribution of approaches based on machine learning. He/she will develop or adapt a methodology based on machine learning (k-means, random forests or others) to estimate excess mortality in the case of insufficiently stratified general population life tables. The methodology developed should be adaptable to the situation where the number of variables not directly observed in the general population life tables is not limited. The candidate will assess the performances of these different methods through simulation studies. He/she will attach particular importance to the interpretation of the methods, with a focus on the epidemiological interpretability of the results obtained. He/she will implement the whole in an R package, preferably, or in Python. Together with the other project investigators, he/she will write the article(s) on this work with a view to publication in international peer-reviewed journals (methodological and/or applied journals).
