Dr. Padmaja Subbarao, MD, M.Sc., FRCP (C)

A world-renowned leader in infant and preschool lung function, Dr. Subbarao is a clinician-scientist in Paediatric Respiratory Medicine, trained in both epidemiology and infant and preschool lung function, who specializes clinically in severe asthma.

She is a Staff Respirologist in Respiratory Medicine, Co-lead of Precision Child Health, and Associate Chief of Clinical Research at The Hospital for Sick Children (SickKids), where she holds a Tier 1 Canada Research Chair in Paediatric Asthma and Lung Health. She is also a Senior Scientist in the Translational Medicine Program of SickKids Research Institute; Professor in Paediatrics, Physiology and the Dalla Lana School of Public Health at the University of Toronto; and Adjunct Professor in Respirology and Medicine at McMaster University.

Dr. Subbarao is also the Director of the world-leading CHILD Cohort Study, a national birth cohort study of 3500 families that is advancing knowledge about the early-life genetic and environmental determinants of health and disease.

Postdoctoral Fellows

Makiko Nanishi

Makiko obtained her MD and completed her pediatric residency and clinical fellowship in pediatric allergy in Japan. After working as a pediatric allergist, she started a research fellowship at Massachusetts General Hospital in the U.S. where she studied bronchiolitis during infancy and childhood asthma under the mentorship of Dr. Hasegawa. She joined the Subbarao Lab in July 2023 with an interest in childhood asthma. Her main project focuses on early-life indoor allergen exposure and the development of allergy and asthma.

Graduate Students

Maria Medeleanu
PhD candidate

Maria is an PhD candidate in Physiology at the University of Toronto, where she completed her B.Sc. in Physiology. Maria is interested in child immunology and the development of respiratory diseases; her thesis focused on respiratory infections in infancy and their potential impact on lung development, as measured by pulmonary function tests.

Myrtha E. Reyna
PhD Student

Myrtha received her M.Sc. in Biostatistics from UofT and her B.Sc. in Bioengineering from the Autonomous University of Baja California, Mexico. She joined the Subbarao Lab in October 2018, conducting inferential analysis of clinical and questionnaire derived data, primarily association and clustering studies. Her current projects focus on identifying growth trajectories, overweight and obesity status, and their association with environmental and perinatal risk factors, as well as the gut microbiome.
