Research

Almost every disease has a genetic component. Often this information is used only to determine how condemned a person is to develop disease. The Segal lab would like to use the genetic information to fix the disease. A guiding principle for our work has been to study how nature does what it does, then attempt to use that knowledge to make useful tools to improve public health, either through increased knowledge or therapeutic intervention. Projects in the Segal Lab revolve around engineering zinc finger, TALE, or CRISPR DNA-binding proteins for specific applications, such as: epigenetic therapy for Angelman and Rett Syndromes, gene therapy to create permanent disruptors of the HIV genome; and studying genetic variation and human diseases, specifically SNP functions in Coronary Artery Disease.
