Graduate Students Play Key Role in Lehigh Mountaintop Summer Program

Of the 105 students in the Mountaintop program this summer working on 31 projects, nine were graduate students who took on significant roles as peer mentors, project guides, and leaders of innovation.

Within the energetic environment of Lehigh’s venerable Mountaintop Summer program, a special dynamic unfolds each year as a handful of graduate students step into roles that encompass both mentorship and research collaboration alongside their undergraduate peers.

Lehigh’s strategic plan, Inspiring the Future Makers, includes a foundational initiative to expand and strengthen the university’s research environment. This initiative aims to enhance research facilities, improve partnerships with key external stakeholders, increase support for faculty seeking external funding, and invest in the development of graduate students, postdocs, and research staff. The Mountaintop Summer program aligns with this strategic vision by offering valuable opportunities for graduate students to engage in meaningful research and mentorship.

This summer, the Office of Creative Inquiry supported 105 students in the Mountaintop program working on 31 unique, interdisciplinary, multi-year projects. Among these students were nine Lehigh graduate students who were active participants on project teams. These students maximized the opportunity to take on significant roles as peer mentors, project guides, and leaders of innovation, as well as bridges between undergraduate participants and faculty project mentors.

For Melinda Westfall, a Ph.D. student in psychology, 2024 was her third summer in a row as a Mountaintop Fellow. She has used the Mountaintop program to deeply dive into a project tied to her Ph.D. research, exploring the origins and transmissions of white nationalist beliefs in adolescence. Westfall considers the Mountaintop program an unparalleled opportunity to delve deeper into her research interests and also develop leadership skills that she will utilize throughout her future studies and career.

“It’s always a challenge for me to find a summer opportunity that aligns with my academic interests at Lehigh and in the surrounding area,” she says. “I feel incredibly fortunate to participate in Mountaintop, where I can continue my research and stay on campus.”

Westfall also sees the program as a building block in her professional development and future career pathway.

“Over the years, I've grown more confident in sharing my opinions and experiences with the undergraduate students on my team. This role is distinct from being a TA, RA, or GA. I take the lead on projects and have learned immensely, which will undoubtedly benefit my future career and academic pursuits” she says.

Nianguang Zhao, a Master's student in financial engineering, says that summer research opportunities are limited for international students due to visa restrictions. Thus, he highly appreciates that Mountaintop offers him a platform not only to work on an innovative project—PA 100 Index, where the team manages an equity index offering investors and financial professionals a comprehensive view of Pennsylvania's economic trends and the overall health of its publicly traded companies—but also to collaborate and exchange insights with other Mountaintop projects.

“I feel lucky to have the opportunity to join the Mountaintop program. I can work on a project I am interested in,” says Zhao. “Additionally, by working with the undergraduate students majoring in computer science on our team, I have experienced the benefits of interdisciplinary research and learned many coding skills and other professional abilities.”

Zhao adds that by exposure to various other projects, he has a clearer idea of what his future Masters’ degree capstone project could be.

In addition to the opportunities Mountaintop offers to graduate students who were Fellows on specific project teams, three graduate students were hired in 2024 as “Mountaintop Guides,” taking on a vital role within the program’s administrative and pedagogical structure. Their responsibilities included providing logistical support, mentoring small project teams, and fostering an environment that promotes progress, accountability, and creativity among the students.

The three guides in 2024 were Garrik Hoyt, a first-year Ph.D. candidate in computer science & engineering; Yu Xie, a 5th-year Ph.D. candidate in industrial and systems engineering, and Alexis Trejo, a rising second-year student in the Master’s (M.Ed) mental health counseling program. According to Bill Whitney, assistant vice provost for experiential learning programs, “having graduate students in the role of program-wide mentors provides connective tissue across all of the Mountaintop projects, and this year’s guides were incredible in their ability to encourage, inspire, and well, guide each and every student. This is a valuable professional development opportunity for graduate students, some of whom don’t have active teaching roles in their degree programs.”

Xie expresses her gratitude for the opportunity, finding it rewarding to witness the progress of various projects and knowing her contributions make a tangible impact.

“I’m not typically outgoing, so I’m incredibly thankful for the chance to engage and improve my communication skills while collaborating with others,” she says.

For Xie, discussing project developments with different student teams is more than just a job; it’s a learning journey. “It broadens my knowledge and introduces me to new concepts. I love exploring interdisciplinary projects beyond my department,” she adds.

Hoyt shares a similar perspective on learning from project teams. He finds value in mentoring undergraduate students, as it allows him to reflect on his own experiences and offer guidance beyond academic topics.

“I would describe Mountaintop as more than just a summer job. It’s a mentorship experience and a personal growth opportunity for me,” he says. “The topics I discuss with students go beyond academics. I also share advice on applying to graduate schools and managing stress.”

Hoyt notes that the interdisciplinary nature of the projects brings together students from different backgrounds, academic years, and majors to work towards a common goal. It's easy for some to feel overwhelmed or "not smart enough."

“I want undergraduate students to understand that those feelings are normal. Everyone starts as a beginner. It's natural for students in other majors to have more knowledge in certain areas, and that's completely fine. That's precisely why the projects are interdisciplinary.”
