The Office of Sustainability hires semester and spring interns. Below, learn more about our fall 2017 cohort. Bios are front row to back row, left to right.

Abigail Pearse is a Smart Labs Intern with the Office of Sustainability. She is a junior majoring in environmental engineering, with minors in mathematics and entrepreneurship & management. She grew up just outside of Philadelphia in Media, PA. In her free time, she loves reading and spending time outside. She shows my commitment to sustainability in her everyday life by sticking to a vegetarian diet because the meat industry has many negative environmental impacts.

Jiyoon Lee is a junior majoring in Public Health and with minors in Global Environmental Change and Sustainability, and Psychology. Jiyoon is excited to be a Smart Labs intern this semester at the Office of Sustainability. She was born and raised in New York City. One thing Jiyoon does to be more sustainable, especially when home in New York, is to always use public transportation or walk wherever possible. In her free time, Jiyoon likes watching movies or looking for good places to eat in Baltimore. She love to travel and try out new things! 

Carley Petrone is the Communications and Marketing Intern for the Johns Hopkins Office of Sustainability. She is currently a senior Global Environmental Change and Sustainability major with a minor in Marketing and Communications. She grew up in Greenwich, CT and loves to play squash as she is the co-captain of the Johns Hopkins Women’s Squash Team. After taking a sustainable food systems course, she was inspired to make her daily life more sustainable by shifting her diet to include more organic and plant-based foods. Carley has found that keeping sustainability in mind when making food decisions is a great way to reduce her environmental impact. She is excited for her senior year and looking forward to working with everyone at the Office of Sustainability!  

Alex Walinskas is a sophomore from Chicago, Illinois. She is a Global Environmental Change & Sustainability major and enjoys the interdisciplinary nature of her studies. On the Hopkins campus, Alex serves on the Student Government Association and participates in Students for Environmental Action and WJHU Student Radio. This year, Alex looks forward to exploring great places for vegetarian and vegan meals in Baltimore in an effort to eat more sustainability.

Isabela Garces is the Air Travel Analyst. I'm from Orange County, California. Bela is studying Computer Science with a minor in Global Environmental Change and Sustainability. She tries to be more sustainable by purchasing vegetables locally from a farm right outside of Baltimore. In her free time, she likes to try out vegan recipes that she finds on YouTube or Facebook.

Kathy Wang is working as a Climate Action Plan Research intern, helping to investigate different topics and issues to update JHU’s plan and vision for sustainability. She grew up in Maryland and am currently studying Chemical and Biomolecular Engineering. To be more sustainable in my daily life, Kathy tries to watch my electricity use, in terms of turning off lights when she leave the room and minimizing my AC use so that it doesn’t turn on whenever out of the house (i.e. at work or school). She is interested in dance, and currently dances with the Modern Dance Company here at Hopkins.

Ideas in Action

Think before you print.

Office paper is highly recyclable, but a lot gets wasted. Waste reduction is more cost-effective than recycling because it reduces the amount of material that needs to be collected, transported and processed.
