One way to increase the scientific network is international collaborations and with different research centers. The conventional research centers usually offer membership to individuals who are at the same geographical location of the centers or should physically attend the centers activities.
few universities or centers are starting adjunctive membership. Do you know any research centers who offer adjunc membership? It would be good anybody that has experience or know a resesrch center that offer adjunct membership without geographical bound, to introduce them in this thread.
