Jon Grinnell is the Francis Morey Uhler Chair in Biology. He spent his youth roaming the hills of coastal California watching the hawks and admiring alligator lizards and rattlesnakes. From the time of his first borrowed binoculars he has been fascinated with wild creatures and places, and now is excited to share those with students. 

As an undergraduate he worked with the last wild California Condors before they were taken into captive breeding programs, and as a graduate student he studied the social and communication behavior of African lions in Tanzania. For years, he worked on lions in South Africa before transitioning to American bison in South Dakota. In each of these projects he eagerly involved research students, as one of his great loves is taking students out into the field to get hands-on experience with animals and ecosystems. 

Recently his attention has shifted to the plight of shallow marine habitats and regularly takes students to study the Mesoamerican coral reef in Belize. Jon feels privileged to have the chance to teach animal behavior, aquatic biology, vertebrate zoology, and other field-based courses at Gustavus, as well as the many travel courses he has led throughout South and Central America and the Caribbean.

Jon is an avid cyclist, scuba diver, hiker, animal watcher, and bow hunter.

Jay Hake is a faculty member in the Business and Economics Department, where he teaches Business Law, Conflict Management, Entrepreneurship, and Social Entrepreneurship. Jay brings an integrated perspective to his faculty role: that of a licensed attorney, seasoned executive, and entrepreneur who has built companies, closed venture financings, and advised startup founders navigating the full arc of early-stage growth.

Jay's teaching philosophy centers on experiential, student-led inquiry. He believes that rigorous frameworks become meaningful only when students apply them to real decisions, and his courses are designed to support this approach, incorporating active discussion, case-based reasoning, and real world application. Whether working through contract disputes, conflict resolution scenarios, or the design of ventures built to generate both economic and social value, his students engage with material that mirrors the complexity of professional life.

Jay’s professional background spans roles as Chief Executive Officer, Chief Operating Officer, and General Counsel across technology, software, and consumer products companies. He has structured equity financings, negotiated complex commercial agreements, managed board and investor relations, and guided organizations through periods of rapid scaling. That operational and legal experience informs his approach to teaching at every stage: from identifying opportunity and building teams, to navigating the legal, ethical, and strategic challenges that define a business’s trajectory.

In addition to his work at Gustavus, Jay leads a boutique consulting firm, serving executives and startup leaders on strategic planning, leadership development, and organizational growth.

Outside of the classroom, Jay is an avid fly fisherman, hiker, lover of the outdoors, and a reader.
 

Dr. Justin Knoepfel, recipient of the Dr. Carlo A. Sperati Award, joined the Gustavus faculty in 2009.

Sarah Erickson Lume grew up near Ann Arbor, MI and had the privilege of spending summers at the international music camp, Interlochen Center for the Arts. This experience instilled in her the love of music making and she began to cultivate the artistic discipline of practicing, rehearsing, and performing within the context of a supportive community. Valuing a liberal arts education, she attended Sarah Lawrence College, outside of New York City while continuing to study oboe with Laura Ahlbeck (Metropolitan Opera) and Randall Wolfgang (New York City Ballet).

Sarah worked at NYC’s Carnegie Hall before entering graduate school at Carnegie Mellon University, where she was the student of her most influential teacher, Cynthia Koledo DeAlmeida (Principal Oboist of the Pittsburgh Symphony). While pursuing a master’s degree in music performance, her momentum flourished both as a musician and as a reed maker. The Philadelphia style of reed making, and the resulting benefits to the oboist, is a specialty she now passes on to her own students. During this time, Sarah also attended Aspen Music Festival in Colorado, and Orford Music Festival, in Quebec.

Her work in the Twin Cities includes chamber music and freelance performances as well as previous work with the Duluth Symphony Orchestra, South Dakota Symphony Orchestra, and Minnesota Waldorf School. Having been an oboe instructor at Gustavus Adolphus College for more than twenty years, Sarah has found teaching to be one of the most fulfilling jobs of her career. She maintains a private home studio and teaches as an adjunct faculty member at other area colleges. Her interests include Alexander Technique, optimal performance psychology, practicing the piano, and recorder, as well as running. Sarah and her husband, a visual artist and professor, have two daughters.
