  About C-MEDS
The Consortium for the Molecular Engineering of Dispersant Systems (C-MEDS) is a research collaboratory involving 43 investigators from 22 universities in the US. The Consortium is based on the premise that dispersants are an essential aspect in the effective management and mitigation of large oil releases from deep ocean environments. The Consortium is funded through the Gulf of Mexico Research Initiative. The Consortium has an Advisory Committee with distinguished scientists from Industry and the Federal Laboratories. In addition to its research mission, the Consortium has a strong education mission to train students in advanced science and technology related to the mitigation of oil spills, and an outreach mission to communicate and provide information on the role of dispersants in oil spills.

Gulf of Mexico Oil Spill & EcoSystem Science Conference
The conference will be held January 26-29, 2014 in Mobile, AL. Conference Registration and Abstract Submission are open.

The CMEDS Annual Investigator Meeting will be held on Thursday, January 30, at the same venue.

CMEDS is putting together a full day symposium on dispersants at the Conference.
