Note that IUBMB membership is via membership of a partner organization. Individuals do not apply for membership in IUBMB. Instead, in order to participate in the programs of IUBMB and become eligible for awards and fellowships of IUBMB, individuals must be members of one of the Adhering or Associated Adhering national societies of Biochemistry and Molecular Biology. The list of such societies can be found here.
For Fellowships involving travel to a different country, priority will be given to applicants who are members of their local Societies. The host country must be a member of IUBMB.
