Jose Guerrero GonzalezThe emphasis of my research is on characterizing the microstructural organization of the human brain using Magnetic Resonance Imaging. More specifically, I am focused on using diffusion-weighted MRI (dMRI) to study microstructural connectivity patterns in brain regions.

I am currently working on the optimization and implementation of dMRI methods that go beyond diffusion tensor imaging (DTI) such us neurite orientation dispersion and density imaging. I am also working on the development of novel approaches for the analysis of dMRI quantitative measures as well as on the development of novel tools for quality assurance of dMRI data acquisition.

Such techniques are to be used for investigating the brain of typically developing individuals as well as the brain of individuals suffering from neurological conditions such as traumatic brain injury and developmental disorders like autism.

My research focuses on intrinsic and extrinsic factors that contribute to language learning in young children with developmental disabilities, including children with Down syndrome, fragile X syndrome, and autism spectrum disorders. Specifically, my research investigates the relationships between parent and child factors during naturalistic parent-child interactions. By including both mothers and fathers, we can better understand similarities and differences in parent behaviors, which may shed light on ways in which parents may need different supports during parent-coached interventions. In addition, I am particularly interested in how we can gain additional insight into interactions and child language development through the use of multiple methods, including standardized measures, behavioral coding, parent report, physiological measures of parent-child synchrony, and Language ENvironment Analysis (LENA).

My methodological research interests lies in the area of experimental design and longitudinal data, including under situations with biased sampling schemes, such as outcome dependent sampling. Current areas of application include communication sciences and language and speech development. In past, I have worked on non-parametric regression methods and on the analysis of brain imaging data.

My research focuses broadly on sensorimotor integration in children with Autism Spectrum Disorder (ASD). I am particularly interested in the neural mechanisms of motor modulation in response to sensory feedback from the environment and how these mechanisms may be different in individuals with ASD compared to those with typical development or other developmental disorders. In order to further characterize these neural mechanisms of sensorimotor integration, I am to use behavioral measures of sensory and motor function along with innovative structural and functional neuroimaging techniques.
