SIGGRAPH 2023 Committee

Meet the SIGGRAPH 2023 program chairs.

Erik Brunvand

Conference Chair

I’m a professor of computer science in the School of Computing at the University of Utah, where I’ve been on the faculty since 1990. As a computer engineer, my research interests are generally related to domain-specific computer architectures, most recently for computer graphics. My interests extend from the high-level design of the processor, and the modification of the graphics algorithms to match the hardware, to the implementation on integrated circuits. As a teacher, I’ve won the University of Utah Distinguished Teaching, the College of Engineering Outstanding Teaching, and the School of Computing Outstanding Teaching awards. As an artist, I’m fascinated with arts/technology collaborations, including teaching courses in kinetic sculpture, and showing my work in a variety of venues, including the SIGGRAPH Art Gallery in 2014. I was the SIGGRAPH Education Chair in 2017 and 2018, co-chair of SIGGRAPH Labs in 2020, and chair of the ACM SIGGRAPH Distinguished Educator Award Committee, 2019–2021.

Nicolas Henchoz

Art Papers Chair

I am the founding director of the EPFL+ECAL Lab, the Design Research Center of the EPFL (Ecole Polytechnique Federale de Lausanne), one of the two Swiss Federal Institutes of Technology. With a career spanning engineering, research, art direction, science reporting, and management, I launched the center 15 years ago in collaboration with the leading art school ECAL (Art and Design University, Lausanne). The EPFL+ECAL Lab brings a unique vision of innovation blending cultural creativity with scientific practices, real-life implantation, and human observation to foster disruptive concepts leading to sustainable adoption. My research outcomes have led to multiple academic contributions at ISMAR, HFES, CHI, SIGGRAPH, DRS, and Leonardo amongst others. My projects have also received several awards including the International Design Festival Berlin, Best app of the year (Splash award), Design Prize Switzerland, and Best User experience (Best of the Web). I am a visiting professor at the Politecnico di Milano and member of the Global Alliance for Media Innovation. I have curated more than 30 exhibitions in institutions like the American Institutes of Architecture (New York), the Royal College of Art (London), the Musée des Arts décoratifs (Paris), and Harvard University. I have been decorated Chevalier des Arts et des Lettres by the French minister for culture and communication.

Chris Wyman

Courses Chair

I am currently a distinguished research scientist at NVIDIA, where we look to invent real-time graphics algorithms while identifying GPU hardware improvements that push performance further. Recently, I have focused on accelerating GPU ray tracing by redesigning algorithms to amortize ray costs, dramatically reducing the rays needed per pixel. Before moving to industry, I was a faculty member at the University of Iowa for a decade. I have been involved with SIGGRAPH in various capacities, including Late Breaking Submissions in 2012 and General Submissions in 2013. I’ve also organized and participated in Courses on various topic, including introductions to next-generation APIs, DirectX Ray Tracing, real-time ray tracing, and physically based rendering. If you are considering submitting a Course, please do! Feel free to reach out to me before the submission date to discuss the process and brainstorm about your content.

Eveline Falcão

Creative Development Director

I graduated from the Federal University of Pernambuco (UFPE), in Brazil, with a bachelor’s degree in industrial design, with a one-year program at the Savannah College of Art and Design (SCAD) where I studied motion media design. Nowadays, I’m part of the design team at Underknown where we develop the static and moving branded graphics for their shows. I love the art and math behind all things 2D and 3D and, down the road, I wish to pursue a master’s degree in computer science since I have a special enthusiasm for the design and engineering dialogue.

Nick Jushchyshyn

Education Chair

My passion for computer graphics and interaction was first sparked by experimenting with a Commodore64 home computer in the late 1900s. This passion ultimately became a career that led me to the 2006 and 2007 SIGGRAPH Conferences, which played a pivotal role in a transition into the feature film visual effects industry. After completing my MFA in animation and visual effects, I began an academic career that continues today as I direct the Digital Media & Virtual Production Program at Drexel University, where I teach immersive media, motion capture, and virtual production. Over these years, SIGGRAPH has been integral to inspiring and enabling my career, teaching, and the students I mentor. I’m honored and excited to be part of the 2023 committee bringing the next iteration of this conference I love to life.

Kalina Borkiewicz

Electronic Theater Director

I create cinematic scientific visualizations, using computer graphics and filmmaking techniques to make science both beautiful and interesting to the general public. I have contributed visualizations of galaxies, tornadoes, molecular structures, and other scientific phenomena to documentary films and immersive audience experiences. I lead the Advanced Visualization Lab at the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign, where I also serve as the director of the Visualization Program Office. In addition, I teach data storytelling and visualization in the Gies College of Business at the U of I. I have a background in computer science and a passion for design.

Ginger Alford

Frontiers Chair

I am assistant chair and clinical professor of computer science at SMU Lyle School of Engineering in Dallas, where I focus on computer graphics, augmented and virtual reality, computer vision, and machine learning. My current research focuses on use of novel light field displays in museum settings. I studied at University of Texas, Texas A&M University, and University of Iowa, obtaining a BS in math, a MS in computer science and engineering, and a Ph.D. in electrical and computer engineering. I’ve worked in graphics-related areas as a software engineer and as an intellectual property consultant. I’ve led development of arts-centered engineering education programs in director positions for private K-12 and public museum settings. I’ve been an active SIGGRAPH volunteer since 2013, serving on several conference committees as Education Liaison, General Submissions Chair, and as chair of the Education Committee for the SIGGRAPH organization.

Josef Spjut

Games Focus Area Chair

As a lifelong gamer, games are what brought me to the field of computer graphics. I pursue my passion for gaming at NVIDIA, where I work as a research scientist. I’ve worked on ray tracing hardware and software, augmented and virtual reality, and most recently have shifted my focus to esports, looking for ways to enable players to achieve the highest levels of performance and skill in gaming. I’m excited by the potential games, and particularly multiplayer games, have to connect people to virtual worlds, and by extension to other people across the world forming new and unique human connections.

Susan Reiser

General Submissions Chair

I teach at UNC Asheville’s STEAM Studio, our 12,000 square foot making space where we emphasize human-centered design through the melding of art, computing, and engineering in projects with and for community partners. While my academic background is computer-science centric, since grad school I’ve taken a variety of art and machining classes. My graphics-related work has transitioned from writing computer vision applications for the Electrophysiology Lab at Duke Med School to creating data materializations with Courtney Starrett. After a 10-year stint in industry, I landed in academia, teaching classes in computer science and developing classes in new media at North Carolina’s public liberal arts college. I enjoy swimming and hiking — especially in the Blue Ridge Mountains and on the California Coastal Trail.
