We are a Computational Biology lab dedicated to analyzing multiple types of biomedical data to gain insight on brain development and brain disorders.
We are at the Lieber Institute for Brain Development.
The Lieber Institute for Brain Development
The mission of the Lieber Institute for Brain Development is to translate the understanding of basic genetic and molecular mechanisms of schizophrenia and related developmental brain disorders into clinical advances that change the lives of affected individuals. The LIBD has the largest, most carefully curated and characterized collection of brains for the study of developmental brain disorders in the world, and generates large related datasets on genotype, gene expression, epigenomics, brain imaging, behavior and medical records. Our group is focused on analyzing these data in collaboration with other LIBD scientists.
Brain genomics, data integration and machine learning
The genome is a complex place with multiple different contexts and relationships between them. One of our goals is to develop new analytical approaches combining graph theory and machine learning to explore the genome in novel ways and find links between genomic context and phenotypes.
Brain Somatic Mosaicism
Somatic mosaicism refers to the fact that cells within an organism have different genomes. Several studies have shown that somatic mosaicism occurs in all brains and that somatic mutations in a subset of cells can cause various rare neurodevelopmental disorders. However, for most individuals, the extent and consequences of somatic mosaicism are largely unknown. The complexity and unique features of the brain suggest that somatic mosaicism can play an important role in behavior and cognition. As part of the NIMH-funded Brain Somatic Mosaicism Network, we work on identifying somatic genomic variants in the brain, the genomic features they are associated to, and how they relate to Schizophrenia and other brain disorders.
Collaborative and reproducible data analysis
We believe that data analysis is better when done collaboratively. One of our projects is a minimalist by design and easy to adopt system to build and share reproducible data analysis workflows. Check it out on github.
