In 2006 he led the transition of Ontario’s newborn screening program to Ottawa leading to the establishment of Newborn Screening Ontario (NSO) at CHEO. In 2008 he was instrumental in the founding of the Better Outcomes Registry and Network (BORN Ontario) at CHEO as a prescribed registry in Ontario. Finally, he is a Principal Investigator for the Canadian Inherited Metabolic Disease Research Network which recently was awarded a $1.5M CIHR Emerging Teams grant for rare disease research. Throughout his career, he has been involved in clinical and translational research related to IEM.

Laboratory Head of Biochemistry and Point of Care Screening 
Matthew P.A. Henderson, PhD, FCACB

Matthew Henderson completed his B.Sc.(Hons) in Biochemistry at Queen's University, and his Ph.D in Biochemistry at McMaster University. After graduate school he went on to post-doctoral fellowships in Clinical Biochemistry and Genetic Epidemiology at McMaster University. Prior to joining Newborn Screening Ontario, Matthew was a Clinical Biochemist at the Children’s Hospital of Eastern Ontario and the Ottawa Hospital. He is a fellow of the Canadian Academy of Clinical Biochemistry.His research interests include the application of computational science to newborn screening.

Laboratory Head of Inherited Metabolic Diseases Laboratory
Nathalie Lepage, PhD, FCACB, FCCMG

Dr Lepage is a full professor in the department of Pathology and Laboratory Medicine at the University of Ottawa, Canada. She is a fellow from the Canadian Academy of Clinical Biochemistry (CACB) and a fellow from the Canadian College of Medical Geneticists.  Dr Lepage has served as a leader (president and/or chair) of several provincial, national and international professional associations, including the Ontario Society of Clinical Chemists, the Canadian Academy of Clinical Chemistry (CACB) and the Pediatric and Maternal-Fetal Division of the American Association of Clinical Chemistry (AACC). She has received the CACB Award for Outstanding Service to the profession of Clinical Biochemistry and the Mentor of the Month Award from the AACC. Her current areas of clinical and research interests are in pediatric metabolic diseases, in pediatric reference intervals, and in laboratory management. 

Operations Director

Laboratory  Head of the Molecular Genetics
Dennis E. Bulman, MSc, PhD, FCCMG, FACMG, DABMG

After completing a B.Sc. in Genetics and a M.Sc. in Microbiology and Immunology at the University of Western Ontario, Dr. Bulman graduated with a Ph.D. in Molecular and Medical Genetics at the University of Toronto in 1993. He then went on to a faculty position at the University of Western Ontario in the Department of Clinical Neurological Sciences. In 1997 he moved to Ottawa where he joined the Ottawa Hospital Research Institute. He is certified by the Canadian College of Medical Geneticists and the American College of Medical Genetics in Clinical Molecular Genetics. He is also a Diplomat of the American Board of Medical Genetics. In 2012, he joined NSO and the Children’s Hospital of Eastern Ontario Research Institute. Dr. Bulman’s research interests involve the identification of genes for rare genetic disorders, the translation of these discoveries to the clinic and the implementation of new molecular testing paradigms to newborn screening.
