JMM meaning in Academic & Science ?

The Joint Mathematics Meetings (JMM) are a mathematics conference hosted annually in early January by the American Mathematical Society (AMS). Frequently, several other national mathematics organizations also participate. The meeting is the largest gathering of mathematicians in the United States, and the largest annual meeting of mathematicians in the world. For example, more than 6000 people attended the 2017 JMM. Several thousand talks, panels, minicourses, and poster sessions are held each year.

The JMM also hosts an Employment Center, which is a focal point for the hiring process of academic mathematicians, especially for liberal arts colleges. Many employers conduct their preliminary interview process at the meeting. Often these interviews take place outside the confines of the conference, so the employers may not appear on the official Employment Center listing.
