Overview

As a clinician-scientist, my main research focus is on understanding why newborns are vulnerable to infection.

I conduct translational research that integrates clinical and lab-based research methodologies including human immunology & molecular biology research, “-omics”/bioinformatics, epidemiology and clinical/interventional studies.

As a neonatologist, I also spend part of my time providing medical care to newborns admitted to the neonatal intensive care unit at the BC Women’s Hospital.

Research

Innate and adaptive immune defences in human neonates across development
This research aims to study of the development of the immune system in humans before and shortly at birth. We create and employ miniaturized immunoassays to characterize immunological responses in infants from 24 weeks of gestation at birth, until the first year. We employ molecular and cell-based approaches such as systems level transcriptomics and single-cell flow cytometry to understand how immune phenotypes link to health outcomes in these populations. Our studies in this area currently focus on neonatal sepsis, innate immunity, CD4 T cell differentiation, COVID-19 and respiratory syncytial virus antibody responses.

Anti-inflamatory treatment for bronchopulmonary dysplasia
We are one of the leading centres of the CIHR-funded MOBYDICK Canadian multi-centre randomized clinical trial to determine whether maternal omega-3 supplementation effectively reduces bronchopulmonary dysplasia in very preterm infants.

Serological responses to COVID-19
With the recent SARS-CoV-2 pandemic, we moved into projects aiming at understanding antibody immunity against this virus at the population level, in infants but also healthy adults. Check out our two ongoing studies by visiting the links below:
