We are pleased to announce the Seventh International Mammalian Synthetic Biology Workshop (mSBW 7.0), to be held in Edinburgh, UK on the week of May 21-22, 2020. The mSBW series has grown exponentially in recent years to become a signature worldwide event. This event brings pioneers of synthetic biology together with experts from other relevant fields to highlight and inspire cutting-edge synthetic biology research, emphasizing both basic and applied science. The workshop format will provide a forum for exposition of the latest developments in the field and discussions of how experts from related fields can benefit from and contribute to mammalian synthetic biology.
