Born in Portland, Oregon, Alex moved to Los Angeles in 1991 to attend the USC School of Cinematic Arts, majoring in film production and still photography. His early post-collegiate years were spent on the camera crews of studio films including Twister, Conspiracy Theory, and Armageddon, learning from top ASC cinematographers and personal mentors including Conrad Hall, Don Burgess, Dean Cundey, and John Schwartzman.
Soon after, Alex became a full-time cinematographer of indie films, music videos, and as the Director of Photography for the Saturday Night Live Film Unit. In 2003, Alex received an Oscar Nomination for the short film Johnny Flynton, which he photographed and also produced. Alex repeated the dual role of cinematographer and co-producer on Green Street Hooligans, about London's football-gang subculture starring Elijah Wood, which won both the Grand Jury Prize and Audience Award at the 2005 South By Southwest Film Festival. He was also the cinematographer of Shanghai Kiss, shot in China and starring Hayden Panettiere. Following, Alex wrote, produced and shot the documentary feature Bigger Stronger Faster*, which premiered in competition at the 2008 Sundance Film Festival and was distributed theatrically by Magnolia Pictures.
In 2009, Alex's 10th season with Saturday Night Live marked his first experimentation with the new HDSLR format, shooting the show's title sequence and most of the season's commercial parodies with Canon 5D and 7D cameras. Alex lives in Venice, California where he continues to write, produce, and shoot for his production company, Third Person.
