Dr Sonia Lewycka, MA (Cantab) MPhil PhD
Senior Epidemiologist, OUCRU, Hanoi
Honorary Senior Research Fellow, University of Auckland
Distance Learning Tutor and Examiner, London School of Hygiene and Tropical Medicine
Sonia is an epidemiologist working at the Oxford University Clinical Research Unit in Hanoi. She is interested in the use of population studies and analyses to evaluate the coverage, equity and impact of public health interventions and programmes. She is currently leading the development and implementation of health behavior change interventions to tackle inappropriate antibiotic use and antibiotic resistance at population-level in Vietnam, as well as an implementation trial of point-of-care testing in primary care settings to reduce antibiotic prescribing. She is also using population datasets to analyse global distributions and determinants of antibiotic use, and building mathematical models to identify intervention points with the largest potential for impact on antibiotic use and resistance. Sonia is also interested in the epidemiology of vaccine-preventable diseases, and is using population datasets to identify the reasons for low vaccination coverage and missed opportunities for vaccination in low and middle income countries.
Previously her work focused on the maternal, newborn, child and adolescent health continuum. Between 2001 and 2014 she worked in Malawi with the UCL Institute for Global Health and led research on population vital events surveillance, cluster randomised controlled trials of community-based interventions to improve maternal and child survival, and the design of a population evaluation of pneumococcal and rotavirus vaccine effectiveness on morbidity and mortality. With the University of Auckland and AUT in New Zealand she worked on population-based research in child, youth and family health, and continues to collaborate on Māori youth health and migrant health research. She has been an advisor to UNICEF/GAVI on developing monitoring frameworks for vaccination coverage and equity, and on identifying health systems bottlenecks for the elimination of mother-to-child transmission of HIV.
Sonia has published more than 40 articles in international journals.
