Its complex symptoms have long made it difficult to accurately diagnose and treat autism. Today, with promising new insights derived from examining the role of the human gut and the gut-brain connection in the development of autism, researchers are making strides in tracking autism’s onset and progression. Among them are recent fecal microbiota transplant studies by researchers such as Professor Rosa Krajmalnik-Brown, a professor in the School of Sustainable Engineering and the Built Environment, part of the Fulton Schools, and director of ASU’s Biodesign Center for Health Through Microbiomes. They are revealing with the help of computational biology more about the gut-brain connection and the potential for new autism therapies.
