The College of Science is a place where passionate people come together each day to push the boundaries of knowledge and to improve our collective understanding of the world in which we live. Here, students and professors alike examine everything from the depths of our oceans to the far reaches of our universe. Each department within the college has unique strengths and expertise in both teaching and research. Our students study diverse subjects such as biomathematics, research chemistry, aquaculture, STEM education and planetary sciences.
