Master of Environmental Studies

Balancing work, life, and a passion for the environment

“I attribute my interest in the environment to growing up on an island and being mindful of the resource constraints of island living,” says Reshmi Nair (Master of Environmental Studies ’08). She’s originally from Andaman and Nicobar Islands, a union territory of India in the Bay of Bengal. “The water, the land, everything is limited there,” she says. Her godfather ran a non-government organization (NGO) there that advocated for environmental protection and the rights of marginalized indigenous people, and, as a kid, Reshmi would work with him during the summers.

This multi-master’s degree student is ready to make a global impact

“My personal philosophy is ‘know more, do more, be more,’” says Zhao Liu (MES/ML/MS `25—expected). “I am constantly seeking to expand my knowledge and skill set, and I find that my enthusiasm and energy levels increase when I am engaged in activities that align with my interests.” As an undergraduate, Zhao pursued dual degrees from the Renmin University of China and the KEDGE Business School in France.

Field work at the intersection of ecology and technology

While Johannes Nelson (Master of Environmental Studies ’23—expected) worked as an elementary school teacher in Lebanon, Senegal, and the Dominican Republic, he taught multiple subjects—but he kept coming back to the environment. “A lot of what inspired me about teaching was environmentally focused. By the end of my time teaching, I found that everything was about the environment—even when it was only supposed to be about math,” he recalls.
