Bio

I investigate algorithms for geometry processing, focusing on computer graphics applications, and have made major contributions to the state-of-the-art research in mesh parameterization, hexahedral meshing, and perception-driven shape modeling. I am particularly interested in leveraging connections between geometry and perception to enable users to create and manipulate geometric content, including garments and 3D-printable artifacts. I received my BSc (1991), MSc (1995), and PhD (2000) from the Hebrew University of Jerusalem. I joined the CS department at UBC in 2003, and was promoted to full professor in 2013. My prior places of study and work also include the Technion (Israel) and the University of Illinois at Urbana-Champaign (UIUC).

I have co-authored over 120 peer-reviewed publications, many highly cited. These include 57 papers in ACM Transactions on Graphics (the premier graphics journal), 47 of them in the SIGGRAPH or SIGGRAPH Asia proceedings, along with 5 papers in the newer SIGGRAPH conference track. I hold multiple patents on methods for garment grading, sketch analysis, and hexahedral mesh generation.

I was the Technical Papers Committee Chair for SIGGRAPH 2023; a program co-chair for Eurographics 2018, 3DV 2018, SGP 2006, and IEEE SMI 2013; and a general co-chair for Pacific Graphics 2018 and GMP 2019. I have served on the editorial boards of ACM Transactions on Graphics, IEEE TVCG, Computer Graphics Forum, Graphical Models, Computers & Graphics, and CAGD.

My awards include the Canadian Human Computer Communications Society 2018 Achievement Award, a UBC CS Faculty Mentoring Award, a Killam Research Award, and an Audi Production Award. My past and present funding sources include NSERC I2I grants, faculty awards from IBM, Google, and Adobe, an NSERC Discovery Accelerator award, and an NSERC DND Supplement.

Research

My research addresses geometric modeling and processing problems, both in traditional computer graphics settings and in multiple other application domains including product design, mechanical and civil engineering, and fashion. I have published numerous papers addressing core geometry processing topics, such as hexahedral meshing and developable surface manipulation. My mesh parameterization methods, particularly the ABF (angle-based flattening) algorithm, are referenced in most books and surveys on geometry processing and are taught in many advanced modeling courses worldwide.

My recent research applies insights about human perception and communication of shapes to algorithmic shape processing and has yielded novel modeling methods targeted at a broad user base. The algorithms I developed accelerate and simplify the creation of virtual models across multiple domains, including fashion and product design. My research in this space has benefited from funding from industry-leading companies, including Adobe, IBM, and Google. My recent work addresses geometric challenges that arise in advanced digital fabrication settings. I am also exploring the use of virtual and augmented reality interfaces for shape communication.

I am passionate about travel and good food (cooking and eating). Once upon a time, I danced salsa and had time to read serious books…
