Dr C Prasad

Dr. Prasad joined the Children's Hospital of Western Ontario (CHWO) in 2003 and is appointed to the University of Western Ontario (UWO) as an Associate Professor.

She earned her Bachelor of Medicine and Surgery in 1982 from the Christian Medical College in India. In 1986 she earned her Doctor of Medicine degree in paediatrics from the Postgraduate Institute of Medical Education and Research Chandigarh India. Dr. Prasad pursued paediatric residency training at Memorial University in Newfoundland and fellowship training in clinical genetics and metabolism at the Children's Hospital of Boston within the Harvard Medical School.
She has an extensive list of publications in peer reviewed journals, is recognized for her work nationally and internationally in the field of genetics and inborn error of metabolism.
