He is further interested in novel ways to empower the study of neuroscience through AI and to empower AI through biologically inspired neural networks. 


Deanna Smith, Ph.D., Associate Professor

In humans, heterozygous mutations in LIS1 typically cause a severe developmental brain abnormality, lissencephaly, in large part due to a critical role in regulating intracellular trafficking. Recently, in conjunction with the Greenwood Genetics Center, we identified a conservative mutation in LIS1 in a child diagnosed with autism. We are currently trying to understand how this mutation impacts LIS1, focusing on potential dysfunction in the axon.
