A Summer of Research Sparks a Passion for Science and Mentorship

Alessandra Cabrera isn’t one for standing still.

Whether she’s in the lab developing new materials or helping fellow students, the fourth-year Dragon thrives on movement, exploration, and discovery. Her journey into research and mentorship began early in her Drexel career with a summer in the STAR (Students Tackling Advanced Research) Scholars Program — an experience that set the stage for everything that followed.

The STAR Scholars Program offers highly motivated first-year students the opportunity to engage in faculty-mentored research, scholarship, or creative projects during the summer after their freshman year. Participants receive a stipend and live in free on-campus housing while completing 350 hours of faculty-guided work.

For her STAR project, Cabrera worked with Caroline Schauer, PhD, the Margaret C. Burns Chair in Engineering and a professor of materials science and engineering. As principal investigator in the Natural Materials and Polymer Processing group, Schauer is developing films infused with food waste to line cans and improve shelf life.

"In the canning industry, there’s a concept called active packaging—packaging designed to either release chemical compounds that keep food fresh or absorb compounds that speed up the spoiling process," Cabrera explains. "The project focuses on a thin film used inside aluminum beverage cans to help preserve their contents."

Cabrera helped test different formulations for these films, using spent coffee grounds from the campus Saxby’s and leftover cranberries from a local drink company.

"Both of these food waste products have antioxidant properties, which help keep oxygen away from food," she says. "Once we created a polymer film, we tested it in different liquids to make sure it would hold up in a can."

As a first-year student, Cabrera valued the opportunity to work alongside more advanced researchers.

"It was an incredible experience—one grad student I worked closely with had also been an undergrad at Drexel and was now pursuing her PhD," she says. "Having that level of mentorship and seeing someone in a position I could aspire to was inspiring."

Cabrera credits Dr. Schauer for fostering an environment that encouraged curiosity and hands-on learning.

"She was a wonderful mentor," Cabrera reflects. "I knew that working in this lab would give me an exploratory approach to materials science, and by the end of the summer, I had gained hands-on experience with a variety of techniques that I could carry forward in my academic career."

Now, as an undergraduate researcher in the A.J. Drexel Nanomaterials Institute, Cabrera continues to build on that foundation. Her current work involves formulating polymer-MXene composite films for multifunctional applications, including energy storage, electromagnetic shielding, and water filtration. She also studies the effects of post-processing techniques on these films, further expanding her expertise in materials science.

Beyond research, Cabrera has also stepped into a mentorship role herself. As a Lead Peer Reader at the Drexel Writing Center, she hosts the Drexel Writing Center Podcast, facilitates professional development discussions, and helps develop writing resources for students and faculty. Previously, as a Peer Reader, she worked one-on-one with students across disciplines to refine their writing, gaining expertise in linguistic diversity and multilingualism.

Her STAR experience provided the foundation for both her research career and her commitment to mentorship, shaping the way she approaches both science and student support today. Now, as she helps guide other students in both scientific and academic spaces, she continues to embody the same spirit of inquiry and growth that first led her to materials science and engineering.
