Before joining WRI, Marissa designed digital advocacy campaigns for environmental organizations around the world through collaborating with Indigenous conservationists in the Philippines and Hawai’i, environmental educators serving low-income students in New York, international wildlife advocates in Viet Nam, and sustainability professionals in New Jersey. While an undergraduate, she served as a founding member of Princeton University's Office of Sustainability's Social Media Team and conducted independent research on how social norm theories can optimize campaigns promoting pro-environmental behavior and sustainable decision-making. Most recently, Marissa received the inaugural Princeton ReachOut Paschen Fellowship for public service, which enabled her to reconnect with her heritage by traveling to the Philippines.
