I am an Early Career Fellow of National Health and Medical Research Council of Australia and a Senior Lecturer with the Discipline of Paediatrics, School of Women’s and Children’s Health at UNSW Australia. I also hold an honorary Research Scientist position within the respiratory department of Sydney Children’s Hospital, Randwick. I am a medically trained respiratory epidemiologist with more than 12 years working experience in the field of epidemiological and population health research in both low- and high-income countries. Prior to coming to UNSW, Sydney I have worked as an Assistant Scientist, Centers for Communicable Diseases at the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b). I have expertise in wide range of research methodologies from outbreak investigation, designing and establishing surveillance, application and analysis of record-linked administrative health data ("big data"); to the design and conduct of randomised controlled trials, clinical surveys, diagnostic studies and longitudinal studies, systematic reviews and meta-analyses. My current work centres around understanding and modifying the intersection between early childhood respiratory infections and chronic respiratory conditions in high-risk populations through epidemiological and health system research. I am also keenly interested in research that influence health services to better address social inequalities and inadequate access to care.
