Priya Wickramaratne, PhD

Research: Dr. Wickramaratne's main research interests are the design and statistical analysis of epidemiologic studies- especially studies of familial aggregation of disease. She has had considerable experience working in the field of family studies of psychiatric disorders. She has published several articles dealing with both the methodology and substance of such studies. The focus of her current research is to evaluate existing epidemiologic approaches to the study of familial aggregation and (where appropriate) to develop improved approaches to the design and analyses of such studies.

Fellow participation:

• Investigate the magnitude of the bias in testing and estimating measures of familial aggregation in epidemiologic approaches, when single ascertainment does not hold.
  
• Develop methods of testing and estimating familial aggregation which allow for other realistic modes of ascertainment.
