As an active instructor in an interactive and interdisciplinary liberal arts environment, she enjoys developing and experimenting with innovative pedagogies to enrich students’ learning experiences. She also values mentoring undergraduate research that fosters critical and independent thinking. At Wooster, she advised several year-long senior independent studies, and at Gustavus, she offers writing-in-the-discipline courses in economics and mentors class-based research projects. In October 2023, her Money and Banking students’ paper titled “The Asian Crisis of 1997” won third place in the Economic Communication category of the Minnesota Economic Association (MEA) Undergraduate Paper Contest. In 2025, Dr. Wang served as a faculty panelist at the MAYDAY! Peace Conference at Gustavus, participating in the teach-in model addressing issues of peace, human rights, and social justice. More recently, she served on the Nobel Conference '63 Planning Committee (theme: AI and Human Agency).

Dr. Wang’s research focuses on Macroeconomics, Monetary Economics, and International Finance. She studies fiscal and monetary policy issues—such as fiscal stimulus, public debt, tax policy, income distributional effects, and monetary policy, using dynamic stochastic general equilibrium (DSGE) models with representative or heterogeneous agents. Her papers have been published in the Journal of Macroeconomics, Review of International Economics, and Economic Modelling. She received the Mansergh Faculty Scientific Research Award at Gustavus in both 2022 and 2025. Her recent project examines the debt-financed stimulus effects in a high-debt economy without monetary independence, considering different schemes and speeds of debt adjustment in a two-sector New Keynesian model. Future projects will examine the redistribution effects between savers and hand-to-mouth agents of debt-financing policies. She regularly presents her work at the The Midwest Economics Association, Canadian Economics Association, Western Economics Association, and Liberal Arts Macroeconomics conferences.

In addition to her research, Dr. Wang actively contributes to professional service. She serves as a reviewer for the Journal of Macroeconomics, Economic Modelling, Contemporary Economic Policy, Cambridge University Press, and the Bulletin of Economic Research. She has also served on the steering and program committees for the Liberal Arts Macroeconomics Conference and was a member of the Board of the Minnesota Economic Association. In 2025 she served as a mentor and a panelist for junior women economists at the CeMENT workshop sponsored by the AEA at the Federal Reserve Bank of Chicago.

Beyond academia, Dr. Wang is a mother of three children. She enjoys architecture, art, photography, and music. Her favorite architects include Frank Lloyd Wright, Louis Sullivan, and Zaha Hadid. She is also inspired by the works of Georgia O’Keeffe, Edward Hopper, and Claude Monet. A musician herself, she plays the piano, violin, and pipa (a Chinese lute). Her favorite composer is Johann Sebastian Bach of the Baroque period.

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 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!
