Paul Mosteller is a native of Philadelphia, PA, where he frequently sang solo roles in much of the major oratorio literature. He was a scholarship student of Beverley Johnson at The Juilliard School in New York, and continued his vocal studies with a number of distinguished voice teachers and coaches, including John Wustman (Urbana, IL), Paul Sommers (Kansas City, MO), John Van Cura (Waco, TX), and Josephine Lott (Long Beach, CA).

Mosteller is Associate Professor of Voice at UAB, where he regularly collaborates with pianist Yakov Kasman in recitals of Russian romances and other vocal literature. He made his western European debut singing Mahler's "Des Knaben Wunderhorn," conducted by Thomas Fulton of the Metropolitan Opera. Additional concert performances include "Carmina Burana," "Elijah," "Messiah," "The Creation," the Bach Passions, the Milhaud Sacred Service, and Requiems of Mozart, Brahms, Donizetti, Duruflé and Fauré. He has appeared as baritone soloist with such diverse organizations as the Concerto Soloists of Philadelphia, Oratorio Singers of Charlotte, Alabama Symphony Orchestra, Birmingham Opera Theatre, Alabama Operaworks, Pennsylvania Pro Musica, Greenwich Choral Society, Westchester Choral Society, and Birmingham City Stages.

Mosteller's performances of newer music include a Roger Sessions 80th-birthday gala at Lincoln Center (New York), collaboration on a grant-winning Continental Harmony project in 2000, and opera performances (including a world premiere by Larry Alan Smith) with New York's American Chamber Opera Company. He has also performed works by Birmingham-area composers Michael Angell, Monroe Golden, and Dorothy Hindman. He is a recipient of several vocal honors including awards from the Kosciuszko Foundation, Metropolitan Opera Regional Auditions, the Bach Aria Group, and a George London Fellowship to the American Institute of Musical Studies in Graz, Austria.

In addition to his UAB faculty activities, Mosteller is Organist/Choirmaster at Temple Emanu-El, Alabama's largest Reform Jewish congregation.
