Three recent scholarly publications from Asbury University faculty are advancing both scientific research and science education while providing students with meaningful opportunities to contribute to the field alongside their professors.
The Shaw School of Sciences is celebrating recent publications by Dr. Marvin Ruffner, professor of biology, and Dr. Laura Walther ’91, professor of chemistry, whose work reflects Asbury University’s commitment to integrating academic excellence, student mentorship, and Christ-centered scholarship.
Ruffner recently co-authored two peer-reviewed studies, both of which involved Asbury undergraduate students as active researchers. One study, published in the Journal of the Kentucky Academy of Science, examined effective methods for propagating northern spicebush, a native shrub commonly found in Kentucky forests.
Conducted entirely by undergraduate students as part of their senior research projects, the study identified refrigeration in moistened potting soil for 12 weeks as the most effective method for promoting seed germination, achieving a 75% germination rate.
His second publication investigated long-term strategies for managing invasive honeysuckle. Researchers found that removing the invasive shrub significantly reduced its abundance over six years, while adding native restoration plantings did not further reduce reinvasion compared to natural regeneration alone.
The publications demonstrate how Asbury students are contributing to peer-reviewed scientific research before they graduate, gaining valuable experience that prepares them for graduate study and professional careers.
What I enjoyed most about the process was getting to know the students better on both a professional and personal level."
“I enjoyed observing their scientific curiosity and helping them sharpen their experimental design, scientific reasoning, and critical thinking skills.”
Students involved in both projects also presented their findings at the Kentucky Academy of Science Annual Meeting, giving them valuable experience communicating scientific research to professional audiences.
Walther’s recent publication focuses on another area she is deeply passionate about: helping students better understand chemistry.
Published in the Journal of Chemical Education, “Bringing Chemical Kinetics to Life: A Week-Long Mini-Unit of Classroom Activities for High School Students” grew out of a master’s thesis project completed by chemistry education graduate Jesse Nugent. Together, they developed an engaging instructional unit designed to help high school students grasp chemical kinetics, a topic often considered one of the most challenging concepts in chemistry.
Teaching chemistry effectively is my passion and the goal of many of my research projects."
“Teaching chemistry effectively is my passion and the goal of many of my research projects,” Walther said. “That moment when a student makes a mental connection and has that ‘ah!’ of understanding is what gets me up in the morning.”
Dr. Cheryl Crowe ’03 Johnson, dean of the Shaw School of Sciences, praised both faculty members for their accomplishments.
The Shaw School of Sciences is delighted to recognize Dr. Marvin Ruffner and Dr. Laura Walther for their recent publications. We praise the Lord for His continued hand of blessing on the hard work of our faculty."
Together, these publications reflect Asbury University’s dedication to fostering discovery, equipping students through hands-on research, and advancing knowledge that serves both the scientific community and the common good.
The Asbury University Shaw School of Sciences includes five departments: Biology & Chemistry, Equine Studies, Exercise Science, Mathematics & Computer Science, and Nursing.
