Talk Title: Unveiling Bias: A Statistician’s Quest for Data Representation in Health Research

Abstract: Despite several proposed roadmaps to increase representativeness in scientific studies, most of the world's research data are collected on selected populations. We rely on summary statistics from well-represented groups and then devise clever statistical methods to transfer/transport the inference for another population. In this talk, I would first argue the obvious: for building fair algorithms and models we need representative training datasets. However, till we have reached the dream of representative big data at a global scale, statisticians have an important role to play. In fact, we have the perfect tools to study the "unobserved" through consideration of selection bias, information bias and alike. I will share examples from my personal journey as a statistician when doing good and timely statistical work with imperfect data (such as data from observational patient care databases) quantified important scientific observations. I will conclude the talk with a call to arms for statisticians and computational scientists to not just develop new methods but also lead efforts for creating, curating, collecting data and pioneering new scientific studies, stepping outside their comfort zones. As public health researchers, our job is not just to predict diseases accurately, but to prevent diseases effectively for communities near and far. I hope to weave a narrative around bias that has multiple definitions and layers.
