As a Professor in the Department of Environment, Geography, and Earth Sciences (EGE), Julie K. Bartley teaches courses in the Geology and Environmental Studies programs. With a background in chemistry and geology, Professor Bartley brings an interdisciplinary perspective to the study of the Earth’s past and present. As a teacher, she strives to know her students as individuals and to inspire interest in the Earth’s past and care for its future. She has also held significant leadership roles at Gustavus, including serving as chair of EGE, as the project director for the Inclusive Excellence Project, and as Associate Provost and Dean of Sciences and Education.

Professor Bartley’s expertise lies in interpreting ancient environments, with a particular focus on the Precambrian. Her research explores how microbial communities shaped and were shaped by the environments in which they lived. She and her students study the fossil record and the chemical signatures left by life hundreds of millions or even billions of years ago. At Gustavus, she actively involves students in this discovery process, supervising numerous undergraduate research projects that range from evaluating stromatolites in Minnesota to analyzing the Martian surface signs of habitability.

Students who collaborate with Professor Bartley might conduct fieldwork, perform laboratory analyses, analyze imagery, work with databases, or some combination of these. In the classroom, Professor Bartley teaches a wide array of courses taken by students across campus. Her teaching philosophy is characterized by a commitment to effective and inclusive instruction and a firm belief that every student is equipped to succeed. Whether a geology major, a general education student, or a first-semester Gustie, students can expect to take an active role in class, have many opportunities for hands-on experiences, and be challenged to grow as they learn. 

Beyond her teaching and research, Professor Bartley serves Gustavus and the broader scientific community in many ways. She recently served as the Faculty Shepherd for the Nobel Hall of Science renovation and addition project and has co-chaired the Nobel Conference. She is a trained facilitator for two national programs: the ADVANCEGeo Partnership, which aims to improve workplace climate in the geosciences, and the Traveling Workshop Program, whose workshops help strengthen geoscience departments.

As the curator of the Chester Johnson Geology Museum, Professor Bartley regularly shares her passion for geology with K-12 students and the public. Whether leading fossil collecting field trips or presenting to local community organizations, she enjoys helping others see the landscape as a "time machine." Her dedication to service was recently honored with the Gustavus Faculty Service Award.

Outside of her professional life, she has served as the chair of a local charter school board and remains an active member of several professional societies, including the Geological Society of America, the National Association of Geoscience Teachers, and the Association of Women Geoscientists.

Marcia J. Bunge, PhD, is Professor of Religion and holds the Drell and Adeline Bernhardson Distinguished Endowed Chair of Lutheran Studies. Bunge earned her BA in Music and English from St. Olaf College (Phi Beta Kappa) and her MA and PhD.in Theology from the University of Chicago. She also studied at the University of Tübingen and conducted research in Germany as a Charlotte W. Newcombe Doctoral Dissertation Fellow. Before coming to Gustavus in 2013, she was Professor of Humanities and Theology at the Honors College of Valparaiso University. Since 2014, she has served as an Extraordinary Research Professor at North-West University in South Africa.  

Bunge’s teaching and scholarship have addressed issues in theology, social and environmental ethics, women’s studies, childhood studies, and inter-religious studies. A central focus of her scholarship is conceptions of and commitments to children in diverse religious traditions. She has published numerous articles and six books on the subject, including The Child in Christian Thought (Eerdmans, 2001) and Children, Adults, and Shared Responsibilities: Jewish, Christian, and Muslim Perspectives (Cambridge University Press, 2012). From 2013–2017, she served as a core collaborator in the interdisciplinary “European Childhoods” project at the University of Oslo and co-edited one of its volumes, Nordic Childhoods 1750–1960: From Folk Beliefs to Pippi Longstocking (Routledge, 2018).

Related to her scholarship on children, Bunge has also written extensively on moral and spiritual formation and Lutheran perspectives on education and vocation. She is co-editor of So that All May Flourish: The Aims of Lutheran Higher Education (Fortress, 2023), translator of selected writings by the German theologian and educator Johann Gottfried Herder, and co-founder of the Gustavus Academy for Faith, Science, and Ethics. From 2023–2025, she contributed to the “Character Development, Ethical Education, and Value Transmission” project co-hosted by Emory University and Heidelberg University.

Drawing on her areas of expertise, Bunge has contributed to academic and advocacy initiatives around the world and secured more than $4.5 million in research, institutional, and civic engagement grants. She lectures widely, has served on international editorial boards and academic committees, and co-founded the Childhood Studies and Religion Program Unit of the American Academy of Religion. Her advocacy work includes child-focused projects, such as Georgetown University’s “Collaborative on Global Children's Issues,” and justice-related initiatives of the Evangelical Lutheran Church in America (ELCA), the World Council of Churches, and faith-based organizations. As a Lutheran theologian and holder of the Bernhardson Chair, she also cultivates relationships between Gustavus and other ELCA-affiliated institutions in the United States and abroad.

Bunge’s collaborations have connected her with colleagues and initiatives across six continents and reflect her enduring commitments to interdisciplinary inquiry, inter-religious engagement, and the flourishing of people and the planet.

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.

Maria Kalbermatten is a scholar and educator in Hispanic Studies. She teaches courses in Spanish language, culture, and linguistics. Her work centers on the study of humor in discourse, with a particular focus on verbal irony, political humor, and the ways humor operates in contexts of power, ideology, and social interaction. Drawing on approaches from pragmatics, discourse analysis, and critical literacy, her research examines how humor functions not only as entertainment but also as a tool for critique, affiliation, and meaning-making in everyday communication.

Her scholarship includes analyses of spontaneous conversations and media texts, exploring how speakers use irony and humor to negotiate relationships, express stance, and challenge dominant narratives. She has a particular interest in humor in Spanish-speaking contexts, including Latin America, and her recent work engages with questions of political discourse, manipulation, and the role of humor in shaping public opinion. Her research has been presented at national and international conferences and contributes to ongoing interdisciplinary conversations about language, culture, and society.

Kalbermatten is deeply committed to student-centered teaching and to creating an engaging, inclusive classroom environment. Her teaching philosophy emphasizes active learning, critical thinking, and the development of interpretive skills that allow students to analyze language and culture in meaningful ways. She frequently integrates her research into her courses, designing classes that invite students to explore authentic materials such as political cartoons, media discourse, and everyday interactions. In courses like Political Humor and Manipulation, she applies a critical literacy framework to help students examine how humor can both reinforce and challenge systems of power.

Kalbermatten teaches across the Spanish curriculum, from introductory language courses to advanced content courses, and contributes to interdisciplinary programs that engage with global perspectives, media, and cultural studies. She values mentoring students at all levels and enjoys supporting them in developing linguistic proficiency alongside cultural awareness and analytical skills.

In addition to her teaching and research, Kalbermatten is actively involved in service at the College and within the broader academic community. She contributes to curriculum development, participates in collaborative initiatives, and engages in professional activities that connect her work to wider scholarly and educational networks.

One of her favorite aspects of teaching at Gustavus is the opportunity to work closely with students in a liberal arts setting, where discussion, curiosity, and intellectual exploration are central. She values the strong sense of community on campus and the ways in which students bring diverse perspectives into the classroom.

Outside of her academic work, Kalbermatten enjoys creative and cultural activities that complement her scholarly interests, including drawing, exploring global cuisines, and engaging with music and the arts. These interests often inform her teaching and contribute to the dynamic, culturally rich learning experiences she fosters in her courses.
