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.

Paschal Baylon Kyiiripuo Kyoore is a professor of French, African/Caribbean Studies. He specializes in French literature of the 19th and 20th centuries, and Francophone Literatures of Africa and the Caribbean. He teaches a range of courses in French and in English. For courses taught in French, his "Francophone African/Caribbean Literatures & Cultures" course that he introduced many years ago marked the beginning of the French program shifting away from focusing on only France and French culture. Francophone cultures have since been the mainstream of courses offered by the French program, and this has made the program more attractive to students. Prof. Kyoore finds it pedagogically and professionally very enriching to teach about the cultures of francophone communities at all the levels of French courses. Also, he founded the African/African Diaspora Studies program, with the collaboration of colleagues, and also created a course in English.

Prof. Kyoore was the first Director of the African/African Diaspora Studies program. He has also served in other administrative positions such as being a co-chair of the Department of Modern Languages, Literatures & Cultures. One other service he renders to the institution is through his involvement with student organizations such as the Pan-Afrikan Student Organization (PASO). He is often invited to do an African xylophone performance at the annual Africa Night celebration organized by PASO; one of the student organizations event that attracts a large community crowd.

Besides journal articles and reviews, Prof. Kyoore has published three collections of folktales, two in English and one in French, and three critical works. He is currently working on a book on womanhood in Dagara folklore and culture. The Dagara are an ethnic group in Ghana, Burkina Faso, and Ivory Coast. He was a recipient of the Gustavus Faculty Scholarly Achievement award; an acknowledgement of his contributions to scholarship at the international level. Also, he was a finalist for a Fulbright Scholar grant to teach and do research abroad. His research focuses mainly on gender issues, the historical novel, and African folklore.
