Researcher in lab

Turn science into action with a freshwater sciences master’s degree.

While earning your graduate degree, you will

  • Explore natural and human-created freshwater systems.
  • Learn from world-class faculty within a small-class environment.
  • Build a multidisciplinary science foundation.
  • Develop in-demand technical and professional skills.
  • Gain research experience working in a scientific lab.

Students in the MS thesis program must be accepted by a faculty member who will serve as the major professor and be primarily responsible for matriculation. 

The School of Freshwater Sciences admits new thesis students for fall and spring semesters.

  • Fall applications are due January 31
  • Spring applications are due October 1

You must meet Graduate School requirements in addition to the following to be considered for admission:

Bachelor’s Degree

A bachelor’s degree in biology, chemistry, economics, geosciences, mathematics, physics, public policy, or other appropriate natural science, social science or engineering discipline.

Undergraduate GPA

Applicant must have at least a 3.0 undergraduate GPA. All of an applicant’s undergraduate coursework completed before award of the first undergraduate degree is included in the GPA computation. For courses that were repeated for credit, each attempt is included.

Those whose undergraduate GPA is below 3.0 should contact Aaron Thiel, Graduate Program Manager, for guidance. Applicants may be considered for admission if they are able to provide evidence of their ability to succeed in graduate study.


All applicants, including UWM students, must upload an official or unofficial transcript into the Panthera admission application system for all work done at higher education/postsecondary institutions. All applicants who are admitted to the Graduate School will be required to submit an official transcript with the degree posted within two weeks of the beginning of their first semester of enrollment.
