A native of Washington, DC, Doug Machiz resides in Oakland where he is co-founder and cellist of Friction Quartet. With Friction, Doug has performed at venues such as Carnegie Hall, New Music For Strings Festival in Denmark, and Lunenburg Academy of Music in Nova Scotia. His quartet is dedicated to expanding the audience and repertoire for contemporary music. They have won grants from Chamber Music America and the Zellerbach Family Foundation, and won second prize at the Schoenfeld Competition in Harbin, China. Friction's recordings appear on National Sawdust Tracks, Albany Records, and Pinna Records. They recently released their debut full length album, Resolve.

Doug is passionate about his educational activities. As a San Francisco Symphony "Adventures in Music" ensemble for the past two years, Friction Quartet has performed in every San Francisco public elementary school. They also regularly perform in schools through partnerships with KDFC, Noe Valley Chamber Music, and other chamber music presenters. Friction frequently visits University and Conservatory composition departments to perform new student works and give seminars on writing for string quartet. Doug has been on faculty at Interlochen Summer Camp and Velocity Music Academy in Austin, TX, and he has maintained a small private studio throughout his seven years in the Bay Area.

In addition to his work with Friction Quartet, Doug is an active free-lance musician. He has performed with Symphony Napa Valley, Fremont Symphony, SF Contemporary Music Players, Post Ballet, Mercury Soul, and Opera Parallel.

Doug earned his Bachelors at Boston University where he studied with Mike Reynolds, his Masters at UT Austin where he studied with Bion Tsang, and his Professional Studies Diploma at San Francisco Conservatory of Music where he studied with Jennifer Culp.

In his spare time, Doug is an avid yogi, road cyclist, backpacker, climber, traveler, and weather geek. Since moving to San Francisco he has become severely addicted to the amazing coffee. He’s enjoys the writing of Haruki Murakami, Hanya Yanagihara, and Ta-nehisi Coates, and films by Richard Linklater, Wes Anderson, and PT Anderson.
