Dr. Antonio Gasparrini, Professor of Biostatistics and Epidemiology at the London School of Hygiene & Tropical Medicine, will be the recipient of the 2021 Myrto Lefkopoulou Distinguished Lectureship.
One of 3 main annual department awards, the lectureship is awarded to a promising statistician– who has earned a doctorate in the last fifteen years– who has made contributions to either collaborative or methodologic research in the applications of statistical methods to biology or medicine, and/or has shown excellence in the teaching of biostatistics.
Modelling epidemiological associations with time-varying variables: A historical perspective and novel approaches
The question of modelling health risks associated with exposures varying over time is a key issue in epidemiological research. A number of methods, including study designs and statistical techniques, have been developed across different research areas such as cancer, environmental, clinical, and pharmaco-epidemiology, some of which sharing interesting features. In this lecture, I will focus on two aspects that have challenged epidemiologists and biostatisticians for a long time when trying to define and quantify health effects of time-varying exposures: how to control for potential confounding effects by other risk factors, and how to model potentially complex temporal dependencies. I will first provide a historical perspective, illustrating how the same problems have been tackled in different epidemiological fields, and then I will discuss more recent modelling approaches that I contributed to.
