Research Focus:

The MPS research lab focuses on finding treatments for the brain in the mucopolysaccharidoses. The mucopolysaccharidoses (MPS) are a group of rare genetic diseases. Current projects include intrathecal enzyme replacement therapy for mucopolysaccharidosis type I, immune tolerance to enzyme replacement, and developing enzyme replacement therapy for mucopolysaccharidosis type III.
