Who We Are

Early-Career Complementologists (ECCO) is a new initiative from the European Complement Network (ECN) and the International Complement Society (ICS), two professional societies managed by researchers and clinicians investigating the complement system in health and disease. ECCO aims to support, engage and connect early-career scientists in the complement field worldwide. 

We share information about great science (paper of the week, clinical highlight of the month, scientist of the month), job opportunities, fellowship-calls, as well as social activities.
