Mission
The Society for Mathematical Biology's mission is to promote scientific collaboration between the mathematical and biological communities.
-
The Annual Meeting of the Society for Mathematical Biology was held in person at the University of Alberta, Canada. The annual conference provides an opportunity for mathematical and biological scientists to interact in a congenial atmosphere. From July 14- July 18, 2025, this meeting was held in Edmunton,Alberta, Canada. Through our Landahl Travel Grant, the Society financially supported the travel of 44 early career researchers from across the world to attend this meeting. The total amount spend on this travel support was $28,034.
Expenses $72,535 · Grants $28,034
-
The Society also provides grants for members of our community to host smaller, focused meetings. In 2025, we financially supported eight such meetings in countries such as Bulgaria, Malawi, Mexico, and Spain.
Expenses $25,076 · Grants $25,076
-
The Society publishes a highly regarded scientific journal, "The Bulletin of Mathematical Biology". There are 12 issues each year available both online and in paper editions. The Society pays the publisher for subscriptions for all members. The publisher remits royalty payments to the Society based on the income generated from the Bulletin. These royalty payments provide the Society with funds used to provide travel support for students participating in the Society's annual conference and other Mathematical Biology related meetings. The Society also uses some funds to provide honoraria to plenary speakers at the annual conference and support conference travel of its officers, board members, and presenters.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those.
