Epidemiology is a methodological and versatile text, applying contemporary research to theory, covering both quantitative and qualitative research methods in epidemiology for students in the health and medical sciences.

It integrates a wide spectrum of case studies and examples from different health and medical disciplines and follows a two level 'methods based' approach differentiating between "basic" knowledge that all students of epidemiology should be familiar with and "beyond the basics" information for the interested or more advanced reader.
