Welcome to the website for the Environmental Science program at UST! 

It is with great excitement that I write this.  The Environmental Science Interdisciplinary Program (ESCI) is thriving at UST!   We have a committed, dedicated group of science, engineering, and social science faculty that have come together to create a unique and important program for students.  It is our goal to provide majors in the program with real-world skills that will form the foundation for careers in environmental science, policy, law, and a whole host of other fields with an environmental 'flavor.' 

Environmental science has been going on at UST for many years now, with biology, geology, and chemistry faculty working together to solve problems that impact aquatic, atmospheric, and sub-surface ecosystems.  However, the ESCI program provides a home for students that might not flourish in a narrow, focused science discipline and that want, instead, to tackle scientific problems from a broader-based perspective.

I am confident that this program serves students well and that the faculty that support it--through their excellent teaching, caring advising, and relevant research--will allow us to educate students that completely fulfill the mission of the university.
