Student Voices

I love that ESS provides so many pathways and research opportunities. You can really immerse yourself in the areas that excite you. Everything connects—the concepts, the research, the people.

Thalia LizarragaThalia Lizarraga · ESS, Class of 2026

I love understanding the foundations of our environment. I want incoming ESS majors to understand, that it's not only about the bigger picture but also the smaller micropicture. Being comfortable in seeing the broad and the focused lens of environmental science will help shape your future path..

Leonardo Aleman MedinaLeonardo Aleman Medina · ESS, Class of 2027

These experiences continue to yield lasting returns. I'm grateful for the people and opportunities that defined my time at UC Merced.
