Engineering the Summer is an annual series following @UChicago engineering students as they embark on summer internships and career experiences.
Yuqin Wang, a UChicago Pritzker School of Molecular Engineering PhD candidate, wants “a cleaner, PFAS-free world.”
PFAS, short for per- and polyfluoroalkyl substances, are a group of synthetic industrial chemicals found in thousands of products. Wang, who is in both the Junhong Chen Research Group at PME and the Seth Darling Group at Argonne National Laboratory is working on ways to detect and remove these stubborn “forever chemicals” from the world’s waters.
She is spending the summer interning at Momentive Performance Materials, Inc., in Pearl River, NY, helping develop PFAS-free materials.
What first sparked your interest in your area of study?
My passion for applied chemistry and physics led me to the field of material engineering during my undergraduate studies. The opportunities of classroom learning and hands-on research experiences to explore how various materials can significantly impact the environment, energy, consumer products, and medicine inspired me to delve deeper into this field and innovate for a sustainable future and improved quality of life.
What research are you focused on at PME?
My PhD research focuses on designing selective molecular probes for the effective detection and removal of per- and polyfluoroalkyl substances (PFAS) in water. By systematically understanding PFAS-related interactions at a molecular level and developing ultrasensitive and selective PFAS sensors, we aim to enhance PFAS monitoring and remediation efforts, addressing the significant water crisis caused by PFAS pollution.
What has been your experience so far this summer at your internship?
My summer internship has been both interesting and instructive. Working with a chemical company that values PFAS issues as much as I do has allowed me to see the impact of federal policies on the chemical industry and its responses. I am honored to be part of a team that is developing PFAS-free products, which aligns with my ultimate research goal of minimizing PFAS pollution and protecting the environment and human health. Additionally, being at a global company with businesses in multiple industries like Momentive has exposed me to diverse real-world research applications and helped me explore my career interests.
Why is an internship a valuable part of your experience at PME?
An internship offers the opportunity to directly observe the real-world impact of material research, helping me vividly understand my responsibility to society and how I can contribute to its improvement. It not only expands my technical skill sets but also allows me to connect with professionals from diverse backgrounds and career levels. Observing how people work in the industry and hearing about their career experiences and perspectives has helped me consider my own career path more thoroughly. These experiences are invaluable in preparing me for the next steps in my career.
What impact do you think your field will have on the world in the next 10 to 20 years?
In the next 10 to 20 years, advancements in material engineering will play a crucial role in understanding PFAS-related health issues and in developing effective methods for PFAS monitoring and treatment, addressing one of the most pressing environmental challenges. Additionally, our research innovations are likely to influence PFAS-related policymaking, which will in turn shape industry practices and regulatory standards. These changes could lead to more sustainable solutions and improved public health outcomes.
What role do you hope to play in that vision of the future?
My PhD experience at PME and the internship have provided me with a comprehensive understanding of PFAS issues, including detection, removal, degradation, and PFAS-free alternatives, while equipping me with essential research skills to address the challenges. In the future, I aim to leverage my knowledge and skills to lead technological innovations that contribute to a cleaner, PFAS-free world.
How has the environment at PME influenced you?
The interdisciplinary and collaborative research environment at PME has exposed me to a diverse array of research topics addressing the world's most pressing challenges. The innovative atmosphere and cutting-edge science constantly inspire me to think creatively and strive for higher quality research.
What else do you think people should know?
It’s always valuable to engage with the world beyond your research field, such as through internships or visits to industry groups, governmental agencies, social organizations or other research labs. This exposure helps you gain new perspectives, broaden your mindset, and expand your professional network, all of which are beneficial for both your research projects and personal career development.
