Looking for an Impactful Summer Research Internship? PEI Delivers

Posted on by Alec Getraer

The summer after my first year, I worked for the Pringle Lab as an ecological research assistant in Gorongosa National Park, Mozambique. I have always loved the natural world, and my internship in Gorongosa allowed me to combine that love with my passion for scientific research. Camping for eight weeks amongst vervet monkeys, warthogs and baboons, and working with researchers in the savanna amidst antelopes, elephants, and lions made the internship a dream come true. That dream was made possible by the Princeton Environmental Institute.

Each year, PEI offers numerous established internships in locations around the world. These opportunities cover a range of environmental topics that address complex global issues related to energy and climate, sustainable development, health, conservation, and sustainability. All the internships last at least 8 weeks, are funded by PEI, and are mentored by a professional organization or Princeton professor. In addition to established internships, PEI also offers an opportunity to design your own internship with a professor if you are interested in a specific research topic.

My PEI internship provided me with real world experience in topics I was learning in classes and taught me how research works in the field.

My PEI internship provided me with real world experience in topics I was learning in classes and taught me how research works in the field. I worked alongside three Princeton Ph.D. students, studying the diet of large mammalian herbivores, identifying trees on termite mounds, and surveying floodplain vegetation protected from herbivory with enclosures. Working with the small community of researchers in the park, I developed research skills such as how to plan field projects and take thorough field notes, while also strengthening my interpersonal skills. Much of our work related to the restoration of Gorongosa’s ecosystem following the ecologically catastrophic civil war in Mozambique, and I witnessed first-hand many of the issues that impact modern conservation and humanitarian efforts in developing countries.

If you likewise have a passion for environmentally related research, you can find detailed internship descriptions and application information on the PEI website. The final deadline for established internships is March 27th, but applications are considered on a rolling basis until positions are filled–so apply as soon as possible!

While it takes a little more effort to make a non-established internship happen, it really is all about taking initiative. My internship in Gorongosa was student-initiated and began simply with a couple of students asking Professor Pringle after class if we could intern with his lab. So if you are interested in creating a student-initiated internship, don’t be afraid to ask–talk to a professor or graduate student about creating an internship and get the ball rolling, and read about past internship projects to get ideas and understand what type of project will succeed. For advice on connecting with faculty members, see this recent PCUR post.

For students who are interested in summer research opportunities in non-environmental fields, the office of undergraduate research offers a student-initiated internship program over the summer called OURSIP. The priority deadline is March 1st, then applications are accepted on a rolling basis until April 1st.

Water Whispering: Memoir of a Winter in the Lab

Posted on by Zoe Sims

February 28. I’m sitting in the basement of Guyot Hall, grinding dried algae with a mortar and pestle.

Vials of algae in the freeze-drier – the first stage of analysis.

At this stage, Caulerpa racemosa, the Green Grape Alga, no longer looks its name. In its natural habitat, Caulerpa’s short stalks bob in the water like clumps of balloons. Its round “leaves” are clustered around the stalks just like green grapes, if grapes were the size of pinheads. But by now I’ve freeze-dried these samples so they are shriveled and stiff, and once I’m done grinding them, the plants are reduced to a uniformly fine olive-green powder.

This is what science looks like for me this winter. It’s not simmering test tubes or even statistics: just the incremental alchemy of water samples and crusty Caulerpa into numbers with the potential to tell a reef’s story.

At a recent job interview, I was asked to talk about the lessons I’ve taken away from my research. One image that came to mind was that of my water samples: the hundred or so bottles that I filled in the ocean in Bermuda, carried back to Princeton in a cumbersome cooler, and spent much of this winter analyzing in the lab. Lined up in the freezer, the bottles are identical but for their labels. These bottles contain the most important data I have – and, for months, they’ve looked exactly like identical bottles of water.

But identical they are not. After many a long lab day, I have numbers to crunch – each bottle associated with nutrient concentrations and nitrogen isotope data that begin to tell the reef’s secrets.  These nutrient data represent the raw materials available to plants and animals on the reef. The isotope data help determine where those raw materials have come from, and what organisms are using them. In my thesis, I am studying how nutrient pollution coming from human sewage changes the geochemistry of Bermuda’s reefs, affecting reef organisms, like Caulerpa, that use those nutrients. This has the potential to shift the ecosystem’s balance: nutrient enrichment puts reef-building corals at a disadvantage, threatening the intricate, biodiverse communities – of anemones and angelfish and everything in between – that corals support.

Looking Back on Undergraduate Research: A Conversation with Kristin Schwab ’09

Posted on by Zoe Sims

This semester, each PCUR will interview a Princeton alumnus from their home department about his/her experience writing a senior thesis. In Looking Back on Undergraduate Research: Alumni Perspectives, the alumni reveal how conducting independent research at Princeton influenced them academically, professionally and personally. Here, Zoe shares her interview.

At Princeton, Kristin Schwab ‘09 was a year-round student-athlete: a striker on the field hockey team, a midfielder on the lacrosse team, and an Ecology and Evolutionary Biology major with interests in medicine and global health. Her independent work on Ghanaian vaccine policy took her halfway around the world, and ignited a passion that continues to shape her work and career.

I relate to Kristin’s path: I also compete year-round (on the cross-country and track teams), and I’ve also done fieldwork abroad for my senior thesis in EEB. Listening to Kristin reflect, I heard some familiar themes – the role of athletics in shaping her Princeton experience, the challenge and meaning she found in fieldwork. Yet Kristin also shared a refreshing perspective on how research has continued to shape her career and personal growth, even now, 8 years after handing in her thesis.

Why Independent Work is Different

Posted on by Zoe Sims

And what is classroom learning good for, anyways?

It is Tuesday morning. From the back of the classroom, I squint at the pictures of fish being projected on the board, and scribble in a spiral notebook. Queen angelfish: yellow ring on head, I write as the instructor describes the species’ habitat. She flips to the next slide. Townsend angelfish, I write, less common.

A school of doctorfish (Acanthurus chirurgus) near one of the reefs I studied last summer. Doctorfish can be identified by the dark vertical bars lining the middle of their bodies.

Slipping into the room, with its rows of desks, overhead projector, and professorial monologue – had felt like donning my own old, well-worn clothes. Sixteen years of traditional education have made this role as a student a familiar one.

Yet this time, the circumstances are unusual, and entering the room as a pupil feels suddenly bizarre. It is mid-June, my third week on the island of Bermuda. Just down the hill from this classroom, the turquoise ocean plays against the research station dock. I am at the Bermuda Institute of Ocean Sciences to conduct a field research project assessing how polluted groundwater affects the chemistry and ecology of near-shore coral reefs. Over breakfast, someone had mentioned that a summer course instructor would be lecturing her class on fish identification today. I have been planning to conduct fish surveys on the coral reefs I am studying, but (rather critically) first need to learn to identify all the fish. The timing of the lecture couldn’t be more perfect, so here I am: hunched over a table in the very back of the classroom, listening and scribbling notes like my thesis depends on it.

On Fieldwork

Posted on by Zoe Sims

In conversation with Yun-Yun Li ‘17

Fieldwork is often – at least in my experience – a perfect storm of challenge. Our time is limited, our advisers are distant, and we are immersed in unfamiliar cultures and experiences. Fieldwork has given me some of my most dramatic and overwhelming challenges – and also my most transformative learning experiences.

I was one of many rising seniors who spent time in the field this past summer, collecting the data which will (if all goes according to plan) serve as the foundation of my senior thesis. I wanted to understand better how fieldwork shapes other seniors’ personal growth and research paths. This week, I sat down over tea with Yun-Yun Li and Alice Frederick, who each did fieldwork last summer in foreign cultures and outside of their mother tongues. We talked about the experiences and lessons we have brought back to Princeton after spending the summer in the field. 

Yun-Yun is an EEB concentrator researching the social, economic, and environmental factors that affect rubber farmers in southern China. Here, we talk about how she found her research question and worked through self-doubt in the field.
