HUGO MOSER RESEARCH INSTITUTE OVERVIEW

Kennedy Krieger’s scientists and researchers are leaders in the worldwide effort to prevent and treat disorders of the brain, spinal cord, and musculoskeletal system.  Our investigators continue to break new ground with innovative magnetic resonance imaging technology, investigate critical areas, such as the role of genetics in developmental disorders, and develop new treatment models and therapies. Kennedy Krieger is committed to sharing our knowledge that can be adapted and used by other healthcare organizations to benefit patients across the country and around the world.

Professional Training Overview

Kennedy Krieger dedicates substantial resources to increasing the number of qualified specialists in the fields of neurological and developmental disabilities. We also take seriously our responsibility not only to improve care through research, but to share that knowledge with others. That is why more than 400 individuals come here to train in a wide variety of disciplines each year. The goals of the Institute’s clinical training programs are twofold: 1) to train leaders in the field of neurodevelopmental disabilities and 2) to help ensure that there is a sufficient number of qualified professionals to meet the needs of children with special health care needs and their families. By training future generations of researchers and professionals – from undergraduate students to current staff – we are ensuring that children everywhere can receive the best possible care.
