Our faculty and staff are committed to developing the next generation’s composers, performers and arts advocates.
Faculty and staff take an active role in Walden’s community life by living alongside the students in dormitories. They eat meals together, participate in various school-wide recreational activities, and share the tasks that maintain the school and assure the safety of all it members. Our philosophy is that by participating together in all levels of community life, faculty, staff, visiting artists, and students can create an environment where close relationships develop and creativity flourishes.
Outside of the summer session, our leaders are distinguished in the fields of composition, theory, arranging, performance, pedagogy, arts administration, and arts advocacy. Our staff holds degrees from institutions such as the Eastman, Mills College, Yale University, Williams College, University of Washington, Luther College, New England Conservatory, College of Wooster, University of Michigan, Peabody Conservatory, Northwestern University, Columbia University, Oberlin College Conservatory, University of California, Swarthmore College, University of Southern California, SUNY-Buffalo, University of Cincinnati Conservatory, SUNY-Stony Brook, New England Conservatory, Harvard University, and Duke University.

Carlos’s teaching approach focuses on instilling joy and fun into music, fostering a sense of accomplishment through personalized and attainable goals for each student.

His compositions were featured alongside those of renowned Brazilian modern composers. Throughout his career, Carlos has composed and recorded four albums of original compositions, with his fifth album currently in progress.

He has taught in Ann Arbor, Michigan’s public schools, with the New York Philharmonic’s Very Young Composer’s Program, and at the Thurnauer School of Music in New Jersey, where he is co-chair of the Composition and Creative Musicianship Program.

Eliza Brown
Faculty, Young Musicians Program
Composer Eliza Brown attended The Walden School as a YMP student from 2000-2002, and has held many roles in the community in subsequent summers, including staff, faculty, and leadership team. Eliza’s compositions have been performed by leading interpreters of new music (including Ensemble Dal Niente, Spektral Quartet, ensemble recherche, International Contemporary Ensemble, Network for New Music, Ensemble SurPlus, and Quince Contemporary Vocal Ensemble), heard on stages throughout the USA and abroad, and released on the Navona and New Focus labels, among others.
Eliza’s music, described as “delicate, haunting, and introspective” by Symphony Magazine, is frequently intertextual, opening dialogues with pre-existing pieces of music, historical styles, field recordings, non-musical artworks, and other artifacts. It is also often interdisciplinary: Eliza has collaborated with practitioners of theater, dance, architecture, poetry, visual art, film, and the sciences, frequently taking on artistic and organizational roles in addition to “composer.” Building intentional, project-specific collaborative processes, with attention to the ethical and equity issues of artistic industries and infrastructures, is an essential part of Eliza’s practice. The monodrama The Body of the State, co-created with six women incarcerated at Indiana Women’s Prison, was commissioned and premiered by Ensemble Dal Niente in October 2017; current projects include Theorem, an interdisciplinary performance work in development with a collective of artists representing many fields, and The Listening Year, a work in progress for New Morse Code based on a year of weekly field recording at Indiana’s Big Walnut Creek. Recent commissioners include a.pe.ri.od.ic, Quince Contemporary Vocal Ensemble, Spektral Quartet and Scrag Mountain Music, Philadelphia Sinfonia, pianist Clare Longendyke, and Classical Music Indy.
Eliza is an Associate Professor of Music at DePauw University in Greencastle, IN, and was recently awarded DePauw’s 2023 Fisher Fellowship for The Listening Year. Eliza holds a B.Mus. in composition from the University of Michigan and a D.M.A. in composition from Northwestern University.
