Dr Caroline Jeffery

Research Associate in Biostatistics

Caroline Jeffery joined the Department of International Public Health in March 2010, as expert in Biostatistics for the Monitoring and Evaluation Technical assistance and Research (METRe) group, led by Prof Joe Valadez.

She completed her PhD in Biostatistics at Harvard University. Her research focuses on disease mapping and the use of spatial information on cases in public health surveillance, in particular the inclusion of residential history in mapping, mapping multiple diseases, and studying the effect of aggregation on the performance of spatial methods. She also holds a MA in Mathematics from Boston College and a Maîtrise in Applied Mathematics and Social Sciences from Paris IX Dauphine.

Research

As part of the METRe group, she is an active biostatistician for continued extension of the Lot Quality Assurance Sampling (LQAS), Respondent Driven Sampling (RDS) and other rapid statistical assessment methods, as they relate to monitoring and evaluation and health systems research.

She also continues an active methodological research program in spatial statistical methods for public health, including geostatistical disease mapping, focusing on the evaluation of these methods, and how precision of spatial data can impact results of analysis.

Teaching

Co-convenor of the Key Themes in International Health and Health Policy module, on the Masters of International Public Health programme.

Co-convener of the Leadership in Health Systems Management module, on the Masters in Global Health.

Masters’ student project supervision: Dr Wole Ameyan (2010-2011); Dr Ayobami Olanrewaju (2013-2014); Audrey Mahieu (2014-2015).
