I am a perinatal epidemiologist with a clinical background in obstetrical nursing. I  undertake clinical trials to evaluate methods of pregnancy and labour management and interventions for mothers at particularly high risk for experiencing adverse perinatal outcomes.  I utilize the British Columbia Reproductive Care Program Perinatal Registry linked to Ministry of Health data to evaluate outcomes and cost of specific methods of delivering obstetrical care.

I am funded to evaluate the introduction of midwifery to British Columbia with an emphasis on neonatal outcomes and cost-effectiveness.  I am validating new standards for intrauterine growth stratified on sex and ethnicity.  I have completed a large CIHR-funded multicentre trial of early labour management and am currently studying risk factors for prolonged latent phase labour.  An additional program involves exploring the utility of screening for exposure to intimate violence in pregnancy as a method of preventing adverse fetal/newborn outcomes. I am conducting a trial of regulated massage therapy for pain management in labour. I am also studying trajectories of women released from provincial prisons and developing predictive measures of recidivism based on health and social networking parameters.  I am also funded to carry out a knowledge translation study aimed at reducing variation in rates of caesarean section across B.C.’s health authorities.
