Claire Beckley
I love the Marine and Freshwater Biology program because it provides lots of hands-on experience and practical labs. I also love how we cover everything from evolution to ecology and physiology and much more. We also learn about all types of aquatic ecosystems and how they are unique, which is super interesting.
