Dr Cattram Nguyen
Cattram Nguyen is a postdoctoral biostatistician (Senior Research Officer) at MCRI, where she has joint appointments with the Clinical Epidemiology and Biostatistics Unit, the New Vaccines Group and the Asia-Pacific Health Research Group. She also has affiliations with the University of Melbourne Department of Paediatrics and the Victorian Centre for Biostatistics.
Cattram completed a PhD in biostatistics in 2015 (University of Melbourne) which focused on multiple imputation and missing data methodology. She also has a Master of Biostatistics from the University of Melbourne (Biostatistics Collaboration of Australia). During her Masters, she spent several periods abroad, including internships at the World Health Organization and the Research and Training Centre for Community Development in Vietnam.
From 2014-2016, Cattram was a biostatistician/research fellow in the Transition to Contemporary Parenthood Program of the Judith Lumley Centre (La Trobe University). She has also worked at the Centre for Biostatistics and Clinical Trials at the Peter MacCallum Cancer Centre, where she coordinated seven multi-centre cancer clinical trials at various stages of development and conduct.

Cattram’s research portfolio spans statistical methodology and applied research in maternal and child health, with a focus on vaccines and vaccine preventable diseases in the Asia-Pacific region. She has been working in pneumococcal vaccine research since 2014. Major projects include pneumococcal conjugate vaccine (PCV) trials in Vietnam and the Gambia, and PCV impact evaluations in Fiji, Mongolia, Laos, and Papua New Guinea.
Cattram's PhD research focused on multiple imputation, a statistical technique for handling incomplete data. As part of her PhD, she evaluated methods for checking the goodness-of-fit of models used in multiple imputation. She continues to conduct research in multiple imputation methods (as part of an NHMRC project grant on missing data methods), and is part of the Missing Data research group of the Victorian Centre for Biostatistics.
She is also involved in teaching biostatistics through the MCRI and the Victorian Centre for Biostatistics. She is also co-supervising 5 PhD students through the University of Melbourne.
