About

Yulia Gryaditskaya is Assistant Professor at CVSSP and the Surrey Institute for People-Centred AI, where she leads the Computational Creativity and Modeling Lab (CCMLab) and is a co-director of the SketchX group. Her main research interests lie in 2D and 3D generative AI.

Before joining CVSSP, she was a postdoctoral researcher (2017-2020) at Inria, GraphDeco, under Dr. Adrien Bousseau, where she studied concept sketching techniques and worked on problems of sketch understanding and sketch-based modeling. She received her PhD in 2017 from MPI Informatik, Germany, advised by Prof. Karol Myszkowski and Prof. Hans-Peter Seidel. Her PhD focused on High Dynamic Range (HDR) image calibration, capturing HDR video on a mobile device, tone mapping of HDR content, structured light fields, and editing materials in such light fields. While working on her PhD, she spent half a year in the Color and HDR group in Technicolor R&D, Rennes, France, under the guidance of Dr. Erik Reinhard. She received a degree (2007-2012) in Applied Mathematics and Computer Science with a specialization in Operation Research and System Analysis from the most prestigious university in Russia: Lomonosov Moscow State University, Faculty of Computational Mathematics and Cybernetics.

Yulia’s work has been published in top graphics and vision journals and conferences: including multiple publications in ACM Transactions on Graphics, Computer Graphics Forum (CGF), IEEE Transactions on Image Processing (TIP), ACM SIGGRAPH, ECCV, ICCV, CVPR and IEEE 3DV. She also co-authored an international patent, based on her CGF publication.

She frequently serves as a reviewer, program committee member, area chair and organizer in a large range of journals and conferences. In particular, she served as a program committee member (area chair) for SIGGRAPH Asia 2021,2022 and SIGGRAPH 2022,2023.

She led the organization of the popular Sketching for Human Expressivity Workshop Series (ICCV’21 and ECCV’22). She is frequently invited as a speaker. Among others she gave keynote talks at the ECCV 2022 workshop: "Drawings and abstract Imagery: Representations and Analysis" (DIRA) and CogSci 2022 workshop "From Images to Symbols: Drawing as a Window into the Mind".
