German Visiting Scholars Present Biotechnology Research at GSSM

HARTSVILLE, S.C. (Oct. 6, 2025) – On Sept. 30, the South Carolina Governor’s School for Science & Mathematics (GSSM) hosted the Johanna Wittum Schule Visiting Scholars Research Seminar, part of the Research Experience Scholars Program. The event showcased the work of three international students from Germany in partnership with Clemson University’s Pee Dee Research & Education Center (PDREC).

The visiting scholars, Selin Müller, Lilly Schubert and Hannah Vrancken, presented their biotechnology research to GSSM faculty, staff, peers and invited guests. Their projects focused on:

• Reducing peanut allergenicity through genetic modification
• Improving wheat digestibility for individuals sensitive to gluten
• Reducing toxicity from Aspergillus, a fungal pathogen that threatens South Carolina peach crops.

The students agreed that the program was both academically enriching and culturally rewarding. “This six-week program was a great opportunity, not only educationally but also culturally,” said Selin Müller, a visiting scholar from Johanna Wittum Schule. “It was interesting to explore different parts of the country while gaining real experience in the lab.”

The program is part of a 17-year partnership between GSSM and Johanna Wittum Schule, expanded through collaboration with Clemson PDREC researcher Dr. Sachin Rustgi, who has mentored GSSM students since 2017 and began research mentorship in this international exchange in 2022. Earlier this summer, the families of Müller, Schubert and Vrancken hosted three GSSM students in Germany while they conducted research at the German Cancer Research Center in Heidelberg.

"Working with high school seniors from the Johanna Wittum Schule is my way of giving back to Germany,” said Dr. Sachin Rustgi, associate professor of molecular breeding in Clemson’s Department of Plant and Environmental Sciences. “The invaluable training in research and life I received from my German mentor now comes full circle as I guide these young, curious minds. Their enthusiasm not only drives their own growth but also reignites energy within us.”

Through the Research Experience Scholars Program, participants gain advanced lab skills, mentorship from university-level scientists and the opportunity to collaborate across cultures on agricultural and health challenges. Their research contributes to Clemson’s ongoing work in genetic crop improvement, disease resistance and food safety.

“This partnership provides our students and their peers abroad with experiences that go far beyond the classroom,” said Danny Dorsel, president of GSSM. “We are proud to welcome these visiting scholars to our campus and to be a part of international collaborations that inspire the next generation of scientists.”

The partnership highlights GSSM’s commitment to providing world-class STEM experiences that reach beyond state and national borders.
