Biological Networks

In collaboration with Laszlo Barabasi's group, we are using healthcare claims databases and other sources of data (about genetic and metabolic networks) to study the role of network phenomena in disease initiation and progression.  We have constructed a large-scale phenotypic "diseasome" that uses co-expression of diseases in patients to ascertain the links between diseases.  This network map can then be combined with information on metabolic and genetic networks to help discern the determinants of illness co-expression.
