The Biomedical Engineering Society (BMES) is the professional society for biomedical engineering and bioengineering and provides a range of professional services for faculty and students including accreditation, potential licensure, publications, scientific meetings, global programs, and diversity initiatives. Their mission is to promote and enhance knowledge and education in biomedical engineering and bioengineering worldwide and its utilization for the health and well being of humankind.
Each year the Center for Biomedical Engineering provides Brown undergraduate students who are presenting their research support up to $800 (exceptions subject to approval by the Director) to attend the annual meeting of the BMES.

BMES charters and supports over 100 BMES Student Chapters and Brown's local student chapter of the Biomedical Engineering Society is University funded but otherwise entirely student driven.  The Brown BMES is the primary entry-level professional society for Brown Biomedical Engineering Concentrators. Its activities range from the educational and career-focused activities already discussed to aggressive recruitment of potential concentrators among first and second year students.

Activities vary from year to year but in the past, the Brown BMES has sponsored a career lecture in the fall with presentations by practicing biomedical engineers following by informal networking. It has also co-sponsored and co-organized along with the Brown Biotechnology Interest Group (BIG) a Career Fair in the Spring in which representatives from 20-30 companies visited campus, set up booths to meet with and recruit students, and ran formal breakout sessions on topics ranging from traditional career pathways to alterative careers for biomedical engineers, (e.g. regulatory medicine, patent law). Finally, Brown BMES has sponsored an annual site visit to local firms engaged in biomedical engineering.
