Chris Nolting
Chris Nolting has been a Visiting Assistant Professor of Physics at Gustavus since 2023. In his classes, he focuses on including many worked example problems and opportunities for hands on learning in groups, and as many physics demonstrations as possible. As a computational astrophysicist, he enjoys showcasing examples related to astronomy whenever possible. His research focuses on the study of galaxy cluster environments and powerful jets from active galactic nuclei, supermassive black holes at the centers of galaxies that accrete matter and power some of the brightest objects in the universe. This work is mainly done through numerical simulations on compute clusters and supercomputers using up to tens of thousands of processors simultaneously. Gustavus students working on research with Chris learn coding languages and data visualization techniques, and even 3D print some of the structures they simulate.
Chris is the faculty advisor to the Society of Physics Students and the Gustavus Engineering Club.
Outside of Gustavus, Chris a self-identifying nerd. He is a lover of board games, magic the gathering, Marvel movies, anime, and going on walks with his dog.

Espen Fredrick
Espen Fredrick is a Visiting Assistant Professor of Physics. A 2021 Gustavus alumnus, Dr. Fredrick earned his Ph.D. in Physics from the University of Texas at Arlington in 2025 before returning to the college, bringing with him a strong commitment to undergraduate education and student-centered research.
In the classroom, Dr. Fredrick emphasizes preparing students for future careers in science and related fields through a teaching philosophy centering on helping students develop the habits needed for independent problem solving. His favorite courses to teach include electromagnetic theory and quantum mechanics, where he enjoys helping students contextualize new mathematical formalisms to build their own physical intuition.
Dr. Fredrick’s research focuses on space plasma physics, particularly the interaction between the solar wind and Earth’s magnetic field. His work aims to improve predictions of how and when solar wind disturbances impact near-Earth space, contributing to a broader understanding of space weather and its effects on technological systems. At Gustavus, he is interested in involving undergraduates in research that emphasizes the accessibility of computational physics and empowers students to conduct meaningful research beyond traditional settings.
Beyond teaching and research, Dr. Fredrick currently assists students who operate the Olin Observatory, helping them gain hands-on experience with astronomical instrumentation. He values close collaboration with students and sees mentoring as one of the most rewarding aspects of his role. He is excited to help students grow as scientists, problem solvers, and future leaders.

Steven Mellema
A Minnesota native, Steve Mellema received his undergraduate degree (with majors in physics and mathematics) from Gustavus Adolphus College in 1972. Following his graduation, he spent six years in Malaysia as a teacher and trainer with the United States Peace Corps. He subsequently attended graduate school at Ohio University, receiving a Ph.D. in experimental nuclear physics in 1983.
Following postdoctoral positions at Ohio University and the University of Wisconsin, he joined the faculty at Gustavus in 1986. He taught in the physics department through 40 years of graduating classes, and also served three terms as chair of the department.
As an active member of the American Association of Physics Teachers, Steve incorporated the results of physics-education research into his own teaching of physics for more than three decades, including peer instruction, cooperative-group problem solving, computer simulations, and studio methods. Steve was fortunate to receive two Fulbright Scholar appointments to Malaysia, and used them to bring some of those advancements in physics pedagogy to his adopted "second home'", teaching at the School of Physics at Universiti Sains Malaysia in Penang.
Over the years, he has also led four study-abroad courses taking Gustavus students to visit and study Malaysia. Steve retired from active teaching in 2025, and is currently a Research Professor of Physics.

Rebecca Fremo
Rebecca Taylor Fremo (Professor of English) earned her Ph.D. in Rhetoric and Composition at Ohio State University after completing her BA and MA in English at Virginia Tech. In the nearly three decades she’s spent at Gustavus, she’s served as English department chair, English co-chair, Director of Writing Across the Curriculum, and Director of the Writing Center. But Fremo’s real passion is teaching writing, and she’s been awarded the Edgar M. Carlson Award and the Swenson and Bunn Award for this work. Fremo likes nothing better than rolling up her sleeves and sitting side by side with student writers as they work through the challenges of sharing their stories. Fremo has published a variety of scholarly essays about teaching writing, but she’s most excited about her work as a creative writer. She recently completed a memoir titled Controlled Burn, which applies her observations as a gardener to her experiences raising three neurodivergent sons. Her poems and essays appear in journals including Mud Season Review, Mankato Magazine, Full Grown People, Paper Darts, and Water~Stone Review. She is also the author of one collection of poetry, Moving This Body, and a chapbook of poems titled Chasing Northern Lights. When she’s not at work, she’s probably in her garden or daydreaming about her next visit to the North Shore. She’s originally from Richmond, Virginia and still dreads the Minnesota winters–but the summers are worth it!

Yumiko Oshima-Ryan
Dr. Yumiko Oshima-Ryan began teaching at Gustavus in 2004. She enjoys teaching private piano lessons and establishing relationships with her students that focuses on trust and integrity. At her piano studio, students cultivate musical, technical, historical, and theoretical features of piano repertoire which they select to perform for their recital. Students focus on developing piano skills which are vital for artistic self-expression. Dr. Oshima-Ryan values mentoring students as they face their challenges, find new perspectives, and most of all, promote self-belief. All of these things ultimately provide deeper meaning and joy to their performance and creativity.
A native of Japan, Yumiko also teaches keyboard courses to students of all levels, including total beginners. Along with keyboard skills courses for music majors and minors, she offers courses on how to practice and prepare performances, as well as on wellness for musicians.
Dr. Oshima-Ryan believes musical performance is one of the most valuable opportunities students can have, and that it represents a core value in the music department of a liberal arts college. As an instructor, she also values sharing the experience of her own performances with students.
Her recordings, "Piano Works for the Left Hand - Takashi Yoshimatsu" and “From Afar,” are published by the Naxos Records label and available to stream on major digital platforms, including iTunes, Spotify, and Amazon. "Piano Works for the Left Hand" was selected as a special edition in the August 2022 issue of Record Geijutsu, a top music review magazine in Japan. Dr. Oshima-Ryan hopes this album inspires and encourages people rehabilitating after injury or fighting a major illness, such as cancer. The album includes pieces which were written for the composer’s respected friend, Izumi Tateno, who lost the use of his right hand after a cerebral hemorrhage. She wants the listeners to get past the idea of the left hand as the overlooked partner of the dominant right. She wants them to see, instead, that through courage, compassion, and creativity, the limitations of human frailty can be overcome.
Recently, Dr. Oshima-Ryan started collaborating with the Department of Theatre and Dance at Gustavus by creating original music for dance performances. Performances, recordings, and lectures are available online.
