Extend Your Meeting Experience: Connect With Colleagues Before And After The AANS Annual Scientific Meeting

The AANS has led the neurosurgical field in dynamic educational offerings and interactive opportunities of any major neurosurgical meeting. Meeting attendees and AANS members can extend their experience through AANS’ professional networking website, AANSConnect ®: • Interact with Presenters, Attendees & Colleagues through Online Discussions; since many presentations are being streamed live to AANSConnect ®, you can discuss these with those attending the meeting virtually as well (see below). • Select the Annual Meeting tab (2013) for discussions and news about speakers, presentations and annual meeting events. Discuss research, arrange to meet people or learn more about what others are saying about the meeting sessions. • Remember the days when researchers stood by their posters tacked onto bulletin boards to talk about their research? Now there’s no set schedule. Electronic poster presentations are available for review and discussion. Post comments, ask the poster presenter questions or to discuss the poster with neurosurgical colleagues. • Presenters are invited to translate their work into other languages and post those in AANSConnect ® for AANS International Members.

Not sure how to use AANSConnect ® to keep in touch with your colleagues? Try these ideas: • Send colleague requests to people you meet so you can keep in touch after the meeting. • Find people with similar research or subspecialty interests, or join groups around areas that interest you. • Start a group for alumnae of your medical school or residency program; you and other alums can post news about reunions, jobs, moves or post photos from alumnae events.
