Philosophy of Care

I believe that every individual is unique and should receive "personalized health care" tailored to meet each individual's specific needs. Our team is passionate about providing state-of-the-art medical care with compassion and understanding. Genetic conditions are often life long and may impact immediate and extended family members - we believe in taking the time to listen to families, address their concerns, explain the genetic testing process, and help them in the decision making process to obtain the best available care for themselves, their child and their family.

Clinical Interests

Dr. Shankar is a pediatric and adult geneticist offering care for a wide range of rare and ultra rare genetic disorders. She is the director of Precision Genomics Program that serves individuals going through "Diagnostic Odyssey" using state-of-the-art Whole Genome Sequencing (WGS). Her special interests and expertise include ophthalmic genetic disorders, non verbal neurodevelopmental disorders/autism spectrum disorders and RASopathies. 

Research/Academic Interests

Dr. Shankar's research focuses on deep phenotyping, whole genome sequencing and other functional studies in individuals with non-verbal neurodevelopmental delays and those going through "Diagnostic Odysseys"  to determine their underlying genetic etiology including new gene discovery.
