Develop an ontology of endophenotypes that maps brain connectivity, neural deficits, and genetic markers into a subject domain theory Develop logic-based methods to encode and classify endophenotypes based on multi-scale measurements Create tools to acquire new endophenotypes and annotate phenotype-genotype findings in online resources such as published literature Develop query-elicitation methods that can evaluate hypotheses about the subject domain theory of endophenotypes using deductive inference
