At CSU, even undergraduates do research, whether it’s at the campus lab or off-campus at an internship. You’ll work with professors and research scientists, and some students present and publish nationally. 

You’ll hear about research, the bedrock of the field from guest speakers throughout the year. And you’ll begin to imagine the career paths you can take with your degree and the impact you’ll be able to have. 

Students who qualify for induction have access to national speakers and networks in the discipline.
