Alexey is a VES Award-winning Principal Research Engineer at Weta FX (formerly Weta Digital). He led development of Weta's proprietary Pahi water and Kora fire simulation systems, which powered the visual effects in Avatar: The Way of Water (2022) and Avatar: Fire and Ash (2025).

Before that, he was at Walt Disney Animation Studios, where he built Splash — a distributed fluid solver with fluxed animated boundaries that generated most of the water effects in Moana (2016) — and Matterhorn, the studio's material point method engine used extensively for snow simulation in Frozen (2013).

His research focuses on computational solid/fluid mechanics, multi-material interactions, and high performance computing. He earned his Ph.D. degree in Mathematics from UCLA (2013) under the supervision of Joseph Teran and Andrea Bertozzi.
