Overview of Biomathematics at Florida State University

 Research in biomathematics at Florida State University began more than two decades ago with the pioneering work of DeWitt Sumners that uses knot theory to understand knotted DNA. Later, in the 1990s, Mike Mesterton-Gibbons began working in biomathematics, applying game theory to biological conflicts, and has now moved on to study behavior and group structure in complex social networks. In the mid 1990s Jack Quine, who like Sumners is a pure mathematician by training, began to apply geometric and algebraic methods to the study of the molecular structure of membrane-spanning proteins. Quine and Sumners teamed up in 2000 to start the Biomathematics graduate program at FSU. This was followed a year later by an undergraduate Biomathematics program. Although Sumners has since retired (but still pursues a very active research career), the program has grown since 2000. In addition to Quine and Mesterton-Gibbons, other faculty in the group include Richard Bertram (mathematical neuroscience and physiology), Nick Cogan (biofilms and biofluids), Monica Hurdal (brain imaging and mapping), and Washington Mio (brain mapping and computational anatomy). Research performed by the biomath faculty is funded by the National Institutes of Health and the National Science Foundation.

The Biomathematics graduate program at FSU is designed for curricular flexibility and interdisciplinary training. All students take courses in statistics and biology, as well as either pure or applied mathematics. The focus of the coursework is determined by the student’s background and interest, and the topic of their dissertation research. Many of our students also interact with faculty in other departments or at other universities. For example, some students have worked with researchers at the National High Magnetic Field Laboratory on research on the atomic structure of proteins, some have worked on brain mapping with researchers of the Laboratory of Neuro Imaging at UCLA, and some have performed biological experiments in labs at FSU and elsewhere. Students participate in one or more seminar each semester. These include the Biomathematics Seminar in which talks are given by graduate students, biomathematics faculty, and faculty from other departments with potential biomath applications. There are also specialized seminars run by biomath faculty members. For example, Hurdal runs a seminar on brain mapping and Bertram runs a journal club that focuses primarily on recent research articles in mathematical neuroscience and mathematical physiology.

Our Students


There are currently 22 Biomathematics graduate students from countries around the world, such as Lebanon, Ethiopia, China, Canada, Mexico, Korea, and Colombia. There are also biomathematics postdoctoral fellows, working either in the department or in faculty research projects. Current student research projects include spatial pattern formation of cortical folds in the brain, a model of eradication of invasive species through the addition of sex-reversed fish to shift the sex ratio of the population over time, mapping brain atrophy in Alzheimer’s disease, shape models for the study of the phenotype of fruit flies, analysis of brain anatomy with methods of spectral geometry, coalition and alliance formation among primates, analysis of bursting electrical oscillations in neurons and pituitary cells, the use of Graphics Processing Units (GPUs) to perform neural network simulations, and models for the production of bird song.  Current and prior students have been authors on publications in Journal of Theoretical Biology, Bulletin of Mathematical Biology, the American Journal of Physiology, Journal of Computational Neuroscience, Biophysical Journal, Journal of Magnetic Resonance, Science STKE, Proceedings of the International Conference on Medical Image Computing and Computer Assisted Intervention, and Proceedings of the International Symposium on Biomedical Imaging. Upon graduation, our Biomathematics students have taken postdoctoral positions at the Mathematical Biosciences Institute, New York University, LSU Health Sciences Center, the University of Texas at Austin, McGill University, and Georgia Tech. 

Our students have been very successful in finding faculty positions and post-docs.        Some of our former student

Admission.

The Department of Mathematics requirements for exam scores, recommendations and statements are necessary for admission. The typical first semester courses in the program require knowledge of undergraduate mathematics including at least multivariate calculus, ordinary differential equations and linear algebra. A basic knowledge of statistics, computer programming, genetics is helpful.

Students intending to get the PhD degree should have taken more advanced courses in mathematics, such as advanced calculus (or real analysis), complex variables, abstract algebra, or topology. 

Biology and programming prerequisites for the program.

 It is helpful, but not necessary, to have some background and coursework in Biology.  Also some programming experience is desirable.  Undergraduate courses can be taken to refresh skills in these subjects, as described below.

During their course of study, students may take for S/U credit an undergraduate genetics course, PCB 3063, and read up on basic concepts in genetics and molecular biology. The genetics course is given in the summer B term (first half of the summer) and in the Fall semester. 

Also students may take for S/U credit an undergraduate course in C++ programming.  These courses are available in the Summer and Fall.

Do not register for undergraduate courses directly, but see the Academic Support Coordinator, currently Esther Diaguila. The registration for C++ is for one hour credit.  These refresher courses do not count for the requirements of the degree.

Financial aid. Most graduate students in mathematics have support from teaching assistantships. An early application is critical for the best chance of financial aid. Also, the orientation program for new TAs is offered in Summer C-term, and those awarded teaching assistantships may be paid a small stipend beginning at that time.


 
Advisement and Supervisory Committees.

Students have a faculty advisor to recommend and approve coursework. For PhD students, a Supervisory Committee, which determines the program, is appointed consisting of at least three faculty members, with at least one from the Department of Mathematics and at least one from another participating department. Substitutions for courses for which the student has prior credit must be approved by the advisor.

Curriculum.

The core curriculum includes 3 courses to be satisfied by all students, and a weekly seminar. Remaining courses are chosen from a list of options, depending on the student's interest and faculty advice. PhD and Master's students in Biomathematics complete 36 hours of approved coursework, of which at least five 3-hour courses must be in the Department of Mathematics. Students completing this coursework are awarded a Master's degree.

Students are expected to have the mathematics prerequisites for all mathematics courses.  For Introduction to Mathematical Biophysics and for Computational Biology student should know basic calculus through differential equations, linear algebra, and some computer programming language.  More advanced undergraduate courses are prerequisite for advanced mathematics course sequences such as Complex Variables, Topology, Real Analysis and Groups Rings and Vector Spaces.
