One of my students presented at SAEM West last year. I think the other regional SAEM meetings also accept medical student abstracts. Submission for the New England meeting are closed though.
What's your timeline in terms of when you would want to present? And what's the topic of your research? Perhaps if you share more details we might be able to suggest an appropriate conference to submit it to. Also, does it have to be a regional conference (if so, why?), or can it be a national conference taking place in the northeast?
CORD is in New York in 2020 for example. Might be a good venue if your topic is related to education.
