Padmaja Subbarao, MD, M.Sc., FRCP (C) 
Associate Chief - Clinical Research, RI

Dr. Padmaja Subbarao is a Clinician-Scientist in Paediatric Respiratory Medicine, specializing clinically in severe asthma. Trained in both Epidemiology and infant and preschool lung function, she holds appointments at the University of Toronto in the Departments of Paediatrics, Physiology and in the Dalla Lana School of Public Health.

Dr. Subbarao’s research program focuses on disentangling preschool wheeze heterogeneity to precisely predict who will develop each type of asthma, monitor its progression and discover the risk factors, exposures and underlying biology associated with each asthma subtype. She is the Director of the CHILD cohort study, one of the largest, most intensively characterized asthma birth cohorts in the world. This world-leading study enabled the discovery of the importance of the gut microbiome for the protection against asthma (cited more than 500 times).

She also established the first infant lung function laboratory in Canada and her early work on the novel multiple breath washout (MBW) lung test helped pave the way for its acceptance by the Federal Drug Agency as an objective outcome measure for clinical trials in Cystic Fibrosis (CF). Her research in early life lung function and risk factors in asthma have enabled the earlier, precise prediction of asthma and monitoring of its progression, thus advancing the diagnosis and treatment of children with asthma.

Dr Friedman’s academic interests relate to the care provided to the hospitalized child. He is an academic leader in the rapidly growing field of Hospitalist Paediatrics, and introduced the highly regarded Sickkids ‘complex care’ program which has developed into a world leader in care for the medically complex child. A current area of focus relates to resource stewardship and overuse of tests and therapies, where he leads the Sickkids Choosing Wisely initiative. He has consulted broadly to childrens hospitals in Canada and around the world related to models of clinical care.

Dr. Friedman was appointed to the examination board of the Royal College of Physicians and Surgeons for Paediatrics in 2006.

Mark Palmert, MD, PhD 
Associate Chair - Outpatient

Dr. Mark R. Palmert joined the Department of Paediatrics as Head of the Division of Endocrinology in September 2007 and held the role until March 2018 when he assumed the role of Associate Chair of Paediatrics for Ambulatory Care. Dr. Palmert graduated from the Medical Scientist Training Program at Case Western Reserve University with an MD and PhD in 1992. He trained in paediatrics and paediatric endocrinology at Boston Children’s Hospital.

Dr. Palmert has a long-standing interest in the regulation and disorders of pubertal timing. He has conducted clinical studies of precocious and delayed puberty and in parallel has directed a laboratory-based program designed to identify and understand genetic factors that regulate the onset of puberty. His interest in the regulation of pubertal timing and in male-female differences in its onset has led to the expansion of his laboratory-based program to include investigation of the bases of sex differences in the brain, including examination of the effects of sex steroids and sex chromosomes on brain structure and function. In the clinical realm, Dr. Palmert has conducted research focused on improving outcomes of youth with type 1 and type 2 diabetes, improving the care of transgender adolescents, and optimizing the use of resources and diagnostic tests within the endocrine clinics.
