In the Information Age, corporations gather an unprecedented amount of data from consumers. Some companies use text mining, artificial intelligence, and the Internet of Things (IoT) to infer the health status of consumers and predict their behavior. Dr. Marks refers to this process as mining for emergent medical data because the raw data that is collected often lacks obvious connections to people’s health. It is only after analysis by machine learning that the data’s health-related properties emerge.

Mining for emergent medical data may have some socially beneficial uses. For example, it could be used to track the spread of communicable diseases or to predict and prevent suicide. However, the data is often collected without consumers’ knowledge or consent, and it allows companies to segment the population based on disabilities, diseases, and other health characteristics. When used to profile consumers, emergent medical data can promote discrimination and inequality through targeted advertising and automated decision-making in a variety of industries including employment, lending, insurance, and education.

Dr. Mark's PhD dissertation will explain how differences between EU and US privacy laws affect mining for emergent medical data and its use in consumer profiling and automated decision making. The project will propose a set of international legal standards for regulating the collection and use of emergent medical data.
