For many students at Scripps and Pitzer Colleges, their college journey is about to stretch halfway across the world.

Thanks to a three-year $446,000 grant from the , Professors Katie Purvis-Roberts and Pete Chandrangsu will lead 18 student researchers in their intercontinental project, “Canal, Chemistry & Community: Understanding Chemical & Microbiological Water Quality & Biodiversity.””
The grant will support summer research experiences in Bangkok, Thailand, with students spending up to 10 weeks exploring the chemical and microbiological water quality and biodiversity of Bangkok’s canal system. Working in partnership with faculty and researchers at , students will engage in both fieldwork along the canals and laboratory work on campus.
Together with Purvis-Roberts and Chandrangsu, their research will explore how biological and chemical inputs impact water quality, how these variables may be interconnected, and whether changes in biodiversity correlate with shifts in water conditions. A key component of the project includes testing the canal water’s potential for domestic and agricultural use.
Answering the ‘Why’: Reviving Bangkok’s Canals through Global Collaboration
“During a previous sabbatical, I was a Jefferson Science Fellow at the US Department of State, and my work focused on energy and environmental issues for the ,” explains Purvis-Roberts, professor of chemistry and environmental science and chair of Scripps’ Department of Art Conservation. “I met policymakers and faculty in the region, including Professor Kanjanee Budthimedhee at KMUTT, who was doing research in a semi-rural community of Bangkok.”
It was Purvis-Robert’s connection to Budthimedhee that sparked the idea for a globally collaborative project focused on water quality and biodiversity.
“[Budthimedhee’s] goal was to understand the needs of people living in the Bang Mod area, then use her urban design background to help them gain better access to transportation and develop economic growth in the area,” says Purvis-Roberts. “She knew that understanding air and water quality in the area was important, so we started a collaboration.”
For the past five years, Purvis-Roberts has partnered with Budthimedhee to bring Claremont students into this work.
“Students from my environmental chemistry class analyze air and water quality data taken in real time,” says Purvis-Roberts. “Professor Budthimedhee’s design students work with our Claremont students to communicate their findings to the community with an art project.”
During the past three years, the class projects have been part of Bangkok Design Week, where residents can interact with citywide art installations.

Rosie Movich-Fields ’26, a senior majoring in environmental science, saw her research displayed last year. Her project combined science, art, and community engagement in meaningful ways.
“It was very gratifying to see our research ideas become a tangible product,” says Movich-Fields. “It made the entire research and design process feel more meaningful.”
This new NSF grant will also allow the Scripps–Pitzer and KMUTT team to significantly expand the work students have already begun.
“In addition to understanding water temperature, salinity, total dissolved solids, and chemistry, we will probe the diversity of the microbiome and the plants and insects along the canal, which will greatly expand the water quality knowledge in the area,” explains Purvis-Roberts.
Launching the Next Generation of Community-Minded Scientists
“This project provides our students with a truly transformative experience,” says Chandrangsu, associate professor of biology. “At the , we emphasize hands-on learning and close mentorship, and this project lets students apply their knowledge of chemistry, ecology, and engineering to address public health questions with real-world consequences.”
Students will also practice scientific communication by translating data into easy-to-grasp stories and outreach that serve local communities.
“Beyond scientific skills, students will develop cultural humility by working side by side with Thai scientists and community members,” explains Chandrangsu. “For students who may never have had an opportunity to travel abroad, this experience will broaden their perspectives on science as a global, collaborative endeavor.”
Kerry Wong ’23, a biology major and Asian American studies minor, traces her passion for the canal project back to her time in Chandrangsu’s lab. Her senior thesis focused on how land use influences salinity and microbial communities in water systems—work that gained her a Projects for Peace Grant, which she used to community-centered research in Thailand.
“My Projects for Peace experience was one of the most formative parts of my journey since graduating from Scripps,” says Wong, who is now an incoming physician assistant studying her master’s in public health at Tufts University School of Medicine. “Collaborating with everyone from longtail boat drivers to environmental engineers taught me to listen first, lead with humility, and make space for local knowledge to guide action. It broadened my understanding of global health systems and deepened my commitment to health education, environmental justice, and community-centered care.”
The Rocky Path to Funding Scientific Research
Applying for the NSF funding was not easy, explains Purvis-Roberts.
“We received positive reviews when we applied two years ago, but were not funded the first time around,” she says. “Now, we can choose the students who are going to work with us in Bangkok, and that is exciting.”
Chandrangsu adds that the process itself sharpened their vision for the project: “Writing the proposal pushed us to think deeply about how to design a program that is scientifically rigorous, culturally respectful, and educationally rich for our students.”
Goals and Outcomes: Improving Daily Life in Bangkok
In Bangkok, students will use innovative, low-cost continuous monitors and paper sensors—many of their own design and build—with DNA analysis to investigate microbial communities. They will also study the biodiversity of plants, animals, and invertebrates that live along the canal system.
“All of the students will host a workshop for school children who live in Bang Mod, where they will learn about water quality and how to protect their canals,” says Purvis-Roberts. “I’m hoping that the project will have a significant impact on both Pitzer and Scripps students and on the Bang Mod community.”
After returning to Claremont, students will continue with data analysis, virtual collaboration with international mentors, manuscript writing, and presentations at scientific conferences. They will also mentor the next cohort of researchers, creating a cycle of peer-to-peer learning across the three-year program. Chandrangsu echoes this, noting that the project’s challenges are also its strengths.
“Field research in Bangkok’s canals comes with unique challenges, from the complexity of sampling in a dynamic urban waterway to navigating language differences, field conditions, and safety concerns,” he explains. “But these challenges are exactly what make the project so rewarding; students will learn resilience, adaptability, and problem-solving skills in a setting where science and society intersect.”
The power of this federal grant exemplifies the kind of globally engaged, hands-on research that is vital to the undergraduate experience at Scripps and Pitzer. Says Chandrangsu,
“Knowing that our research will not only train students, but also contribute to community well-being, is profoundly motivating.”
