Maryann Simmons and Hayley Iben win Academy Awards

CS alumnae Maryann Simmons (B.A. / M.S./ Ph.D. ’01, advisor: Carlo Séquin) and Hayley Iben (M.S. ’05/Ph.D. ’07, advisor: James O’Brien) have won 2020 Technical Achievement Awards (SciTech Oscars) from the Academy of Motion Picture Arts and Sciences for hair simulation systems.

Simmons is now a senior staff software engineer and the technical lead for Hair & Cloth at Walt Disney Animation Studios (WDAS).  She was part of the team responsible for the WDAS Hair Simulation System, which the citation describes as “a robust, predictable, fast and highly art-directable system built on the mathematics of discrete elastic rods. This has provided Disney artists the flexibility to manipulate hair in hyper-realistic ways to create the strong silhouettes required for character animation and has enabled a wide range of complex hairstyles in animated feature films.” According to The Hollywood Reporter, the WDAS System was “used in animated features such as Tangled, to manage Rapunzel’s ultra-long waves.”  While at Berkeley, Simmons was a member of Phi Beta Kappa and the Golden Key Honor Society.

Iben, who is now the director of engineering at Pixar Animation Studios, was part of the team responsible for the Taz Hair Simulation System.  The citation describes Taz as “a robust, predictable and efficient mass-spring hair simulation system with novel formulations of hair shape, bending springs and hair-to-hair collisions. It has enabled Pixar artists to bring to life animated digital characters with a wide variety of stylized hair, from straight to wavy to curly.”  While at Berkeley, Iben was president of Women in Computer Science and Electrical Engineering (WiCSE) from 2004-2007, and a member CSGSA.
