Brief Biography

Dr. Binita Kamath is a hepatologist in the Division of Gastroenterology, Hepatology and Nutrition and an associate scientist in Developmental & Stem Cell Biology at The Hospital for Sick Children (SickKids) in Toronto. 

Dr. Kamath was educated at Gonville and Caius College of Cambridge University in the UK and completed her medical training at the Cambridge University School of Clinical Medicine in 1995. She did her paediatric residency training between several London hospitals including the world-renowned Liver Institute at Kings College Hospital. She moved to the Children’s Hospital of Philadelphia in 2000 to further her specialist training where she completed her Fellowship in Pediatric Gastroenterology and Hepatology. She joined the faculty at the Children’s Hospital of Philadelphia in 2006. 

During her time in Philadelphia, Dr. Kamath developed a strong research interest in cholestatic liver disease and specifically focused on Alagille Syndrome. She worked closely with Dr. Spinner and Dr. Piccoli who had identified the disease gene for Alagille syndrome. Dr. Kamath joined the SickKids staff in 2009 as a Hepatologist and Clinician Investigator. She plans to establish a Canadian-wide Alagille Syndrome Centre at SickKids. Her clinical interests are in paediatric hepatology and liver transplantation.

Research Interests

  • Cholestatic liver disease
  • Alagille Syndrome

Dr. Kamath’s research focuses on inherited biliary disorders. Although these diseases are rare, her research is fundamental to understanding biliary disease mechanisms that has generalizability to other more common and complex bile duct diseases. Her research approach is translational encompassing patient-based studies and collaborations with basic scientist colleagues. 

Dr. Kamath's primary interest is Alagille syndrome, a multi-system disease with cholestasis associated with bile duct paucity – her goals are to understand the phenotypic manifestations, genotype-phenotype relationships and natural history of Alagille syndrome. Recently she has established a collaboration with Dr. Gordon Keller and Dr. Anand Ghanekar to develop a highly innovative protocol to differentiate cholangiocytes from induced pluripotent stem cells (iPSCs). The goal is to derive patient-derived cholangiocytes, which can be used to study disease mechanisms of developmental biliary disorders, for understanding complex biliary diseases and in the future for drug screening.  They have generated exciting preliminary data with iPSC-derived wild-type biliary epithelial cells, which share many of the structural and functional characteristics of mature cholangiocytes. They are currently applying this differentiation protocol from iPSCs derived from patients with cystic fibrosis and Alagille syndrome.

Dr. Kamath’s second focus is a novel area of study to assess the concept of frailty in children awaiting liver transplantation. Frailty is a validated measure of debilitation in the elderly, which is correlated with significant morbidity and mortality. Adult data reveal that frailty measures elements of morbidity in patients awaiting a liver transplantation that are not captured in laboratory evaluations or current organ allocation scoring systems. She has completed a pilot feasibility project to assess frailty in children and have now extended this study to a multi-site collaboration of 13 North American transplant centres, with SickKids as the lead site.
