The Graduate School admissions page is where you can submit, update, check the status of an on-line application, as well as pay the application fee.  But remember that the Biology Department requires completion of a Biology specific application in addition to the Graduate School application.

Full financial support is offered to qualified students accepted for graduate admission who are not otherwise funded. Support includes teaching assistantships and fellowships provided by the university and the biology department, research assistantships generated by individual research grants, and interdisciplinary traineeships and fellowships. Several of our current students hold their own National Science Foundation Fellowships or individual grants from other governments.
