Ralph-Axel Müller, Ph.D. — Professor, Lab Director

Dr. Müller, aka Axel, has specialized in functional brain imaging of neurodevelopmental disorders and typical child development for over 20 years. Following postdoctoral work on functional plasticity in children with early brain damage, he has applied neuroimaging techniques in autism since the late 1990s. He founded the Brain Development Imaging Laboratory in 2001, which became Brain Development Imaging Laboratories in 2016. He is also one of the founding members of the SDSU Center for Clinical and Cognitive Neuroscience (CCN).


Inna Fishman, Ph.D. —  Research Associate Professor, Associate Clinical Director
Research Interests:  Social Neuroscience and Social Brain Networks in ASD; Early Brain Development in ASD

Dr. Fishman’s broad research interests lie in understanding neural mechanisms underlying human social behavior. Her current research efforts focus on applying multimodal approaches (EEG, fcMRI, DTI) to examine the connectivity patterns in brain networks associated with social cognition in autism spectrum disorders (ASDs). Dr. Fishman’s research has been funded by the Autism Science Foundation (ASF) and NIMH (K01 and BRAINS R01 awards). Her current work is focusing on characterizing structure and function of cortical networks at the time of first behavioral signs of autism (at age 1.5-2 years), and tracking changes in brain network organization through the full symptom manifestation at age 4-5 years. For more information on Dr. Fishman’s current projects, see

Ruth Carper, Ph.D.  Research Associate Professor, Associate Director
Research Interests:  Neuroanatomy of ASD

Dr. Carper has two areas of research focusing on the brain bases and long-term phenomenology of autism spectrum disorders. (1) She uses structural MRI and Diffusion Tensor Imaging to study the neuroanatomy of autism, how it changes during development, and how these structural differences help to explain differences in cognition. She is working with other BDIL members to combine measures of anatomical connectivity (DTI) with measures of functional connectivity (fcMRI) to better understand the brain bases of autism-related behaviors in toddlers, adolescents, and mature adults. (2) Dr. Carper also has a strong interest in how adults with autism fare as they age.  She currently leads a study examining 40 to 65 year olds with autism.

Principal Investigators & Faculty


R. Joanne Jao Keehn, Ph.D.  Research Assistant Professor
Research Interests:  Neural and Behavioral Development of Multisensory Processing in ASD

Dr. Jao Keehn’s research interests focus on the development of neural and behavioral mechanisms underlying visual, haptic, and multisensory processing in children with and without autism spectrum disorders. Her work involves the use of multimodal methods, including experimental task paradigms, task-based functional MRI, and functional connectivity MRI among others, to examine sensory development, salience detection, and internalizing behaviors in children with autism.


Annika Linke, Ph.D. Research Assistant Professor
Research Interests:  Neural Mechanisms of Development

Dr. Linke received her doctorate in Cognitive Neuroscience from the University of Cambridge in England and completed a postdoctoral fellowship at the Brain and Mind Institute, Western University in Canada. Her main interest is understanding how brain function changes over the course of development, and how it is altered in neurodevelopmental disorders. She has extensive experience with neuroimaging neonates, infants, children and adults.


Janice Hau, Ph.D. Research Assistant Professor 
Research interests: Neural Circuits and Autism

Dr. Hau received her doctorate in Neuroscience from the University of Bordeaux in France. Her research interests include neuroanatomy of white matter, brain-behavior relationships, lifespan brain development, and neurodevelopmental disorders such as autism. She uses diffusion MRI to investigate brain structure at macro and microscopic scales, in combination with other imaging modalities, to gain insight into the structural and functional organization of the human brain.
