When Emma Landefeld arrived at 51做厙, she envisioned a future as a high school physics teacher. What she discovered instead was a passion that would take her far beyond the classroomand into the cutting-edge world of plasma physics.

Emma credits Duquesne with giving her the freedom to explore. Encouraged to step outside her original plan, she pursued research opportunities that ultimately reshaped her future.

That turning point came during a summer internship at West Virginia University, where she was introduced to experimental plasma physics for the first time. Tasked with building an electron beam to excite plasma, Emma faced challenges that tested her persistence. For much of the internship, her device didnt workbut instead of stepping back, she leaned in.

I challenged myself to understand every part of the system, she said. When I finally found the issue and fixed it, I saw the most beautiful blue glowthe first plasma I ever created.

That moment was more than a successit was clarity. Emma realized that physics wasnt just a subject, but a puzzle she was driven to solve.

At Duquesne, that curiosity was nurtured in a close-knit department where faculty invested in students as individuals. Through mentorship and support, Emma not only built a strong academic foundation but also grew in confidenceovercoming challenges like imposter syndrome and learning to navigate ADHD.

Ive become a more mature scientist and person, she said. I truly feel prepared for whats next.

Mentorship and collaboration played a defining role in Emmas journey. Under the guidance of Ted Corcovilos, she found both support and independence.

Dr. Corcovilos gives his students space to explore their passions. When I wanted to build a plasma device for the advanced lab, he went out of his way to help me make it happen.

Emma also expanded her experience through research at Princeton Plasma Physics Laboratory, contributing to the FLARE project, which studies magnetic reconnectiona process critical to understanding both fusion energy and astrophysical phenomena.

Working alongside scientists and graduate students from across institutions reinforced an important lesson: science is inherently collaborative. The relationships she built continue to support her today, from graduate school advice to late-night questions about plasma physics.

Back on campus, Emmas impact will be lasting. In her final semester, she developed a plasma setup for Duquesnes advanced lab coursecreating new opportunities for future students to explore the field.

Im so excited for Duquesne students to experience plasma, she said.

Duquesnes hands-on curriculum gave Emma a strong technical foundation early on. By her sophomore year, she had already developed skills in electronics, optics, and programmingpreparing her to thrive in competitive research environments.

When I started my first internship, I felt ready, she said. I wasnt overwhelmed by the independence that comes with research.

That preparation carried her through multiple high-level research experiences and positioned her for the next step: pursuing a Ph.D. in plasma physics. After being accepted into several top programs, Emma will continue her journey at Cornell University this fall.

As she reflects on her time at Duquesne, Emma is most proud of the relationships shes built and the moments that defined her experience.

Im leaving with countless cherished memories, she said.

Looking forward, she hopes to make an impact not only through research in astrophysical plasmas, but also through education and outreachbringing plasma physics into classrooms and inspiring the next generation of scientists.

Plasma has incredible applicationsfrom fusion energy to space science, she said. I want more people to see thatand to get excited about it.
