Ting Wang’s lab at WashU has been selected to participate in DARPA’s Epigenetic CHaracterization and Observation (ECHO) program, we will function as the data visualization center for this program. According to DARPA, the “ECHO program has two primary challenges: to identify and discriminate epigenetic signatures created by exposure to threat agents; and to create technology that performs highly specific forensic and diagnostic analyses to reveal the exact type and time of exposure.” (Epigenetic changes are chemical modifications that affect genes, altering their expression while leaving the genetic code intact. Epigenetic changes can occur as natural responses to the environment but can also signal exposure to toxic agents or disease pathogens.)
