DC Discussion Group
With the origins of CASSS in mind, the DC Area Scientific Discussion Group offers an opportunity for CASSS members to meet others who understand what they do in an informal setting and exchange new ideas. They have been bringing people in the field of biotechnology and biopharmaceutical development together since 2014. This group’s mission is "Bringing Together Industrial Challenges in the Development of Biologics with Advances in Science and Technology." Anyone in the greater DC/Maryland area (or for virtual meetings, anyone around the world) affiliated with biotechnology, or interested in learning more about the scientific and technological applications to biotechnology is invited to attend.
