Programme Chairs

Konrad Polthier (Freie Universität Berlin)
Konrad Polthier is full professor of mathematics at Freie Universität Berlin since 2005. He received his PhD from University of Bonn in 1994, and headed research groups a Technische Universität Berlin and Zuse Institute Berlin before joining FU Berlin. His research focuses on discrete differential geometry, applied geometry, geometry processing and mathematical visualization. Results from him have been applied in industry such as computer graphics, computer aided design and architecture. Dr. Polthier has written and co-edited books on mathematical visualization and produced mathematical video films. His video “MESH – A Journey through Discrete Geometry” (, joint with Beau Janzen, Los Angeles) has received international awards including "Best Animation" at the New York International Independent Film Festival. Polthier served as conference chair on international conferences including ACM/Eurographics Symposium on Geometry Processing and SIAM Geometric Design. His professional positions include chair of the Berlin Mathematical School, board member of the Matheon research center and chair of the Berlin Mathematical Society. Since May 2014 he serves as co-editor in chief of Computer Aided Geometric Design. For more details see:

Ergun Akleman (Texas A&M University)
I am a professional cartoonist, illustrator and caricaturist who has published more than 500 cartoons, illustrations and caricatures. I am also a computer graphics researcher who has a background in Electronic and Computer Engineering. I received my PhD in Electrical and Computer Engineering from Georgia Institute of Technology. In the Visualization Sciences program, I teach a wide variety of topics in covering both artistic and scientific aspects of computer graphics. The topics I usually teach include computer animation, 3D modeling, rendering, visual storytelling, image based lighting and compositing. My research work is also interdisciplinary, usually motivated by aesthetic concerns. I have published extensively in the areas of shape modeling, image synthesis, artistic depiction, image based lighting, texture and tiles, computer aided caricature, electrical engineering and computer aided architecture. I also have a significant body of work in subdivision modeling and implicit modeling. My future research goals include finding new ways for physical construction of large scale complicated shapes.

Nico Pietroni (ISTI-CNR)
Nico Pietroni is a researcher of the National Research Council (CNR) in Pisa, Italy. He received an advanced degree in Computer Science from the University of Pisa in 2003 and a PhD in computer graphics from the University of Genova (Germany) in 2009. In 2010 he was a visiting post-doc at the Courant Institute of Mathematical Sciences of New York University. From 2012 he is a permanent researcher at the Visual Computing Laboratory at the National Research Council of Italy (
His research focuses on concepts and practical algorithms for the creation and manipulation of digital shape representation. In particular, his main interests are mesh parametrization, geometry processing for digital fabrication and Architectural Geometry. He recently proposed a new method to create custom microstructures with specific mechanical properties to allows for design and manufacturing of objects with customised elasticity behaviour.

Karina Rodriguez Echavarria (University of Brighton)
Karina Rodriguez Echavarria is a Senior Lecturer at the University of Brighton and member of the Cultural Informatics Research Group. Karina has worked in several national and European projects researching in the areas of digital collections and 3D technologies for cultural heritage organisations producing research outputs in interdisciplinary areas such as computer graphics, information and knowledge management as well as cultural heritage. She is currently the Principal Investigator on the UK EPSRC project "Automatic Semantic Analysis of 3D Content in Digital Repositories" (2014-2016). This research project involves the use of digital fabrication techniques to transform the processes for manufacturing architectural mouldings for historic buildings. Her research interests also include the documentation and visualisation of heritage collections, information and knowledge management, semantic technologies, 3D printing, and the practical aspects of deployment of 3D technologies in the heritage sector. She is member of the Editorial Board of the ACM Journal on Computing and Cultural Heritage (JOCCH).

Asla Medeiros e Sá (Getulio Vargas Foundation)
Asla Medeiros e Sá is a Lecturer and Researcher at School of Applied Mathematics at Getulio Vargas Foundation in Rio de Janeiro since 2007. She obtained her Mathematics Bachelor from the Federal University of Rio de Janeiro in 1999 and her Master degree in Applied Mathematics from the same institution in 2001. Her PhD in Sciences with emphasis in Computer Graphics was obtained in 2006 from Institute for Pure and Applied Mathematics. In 2012 she has been in a post-doc position at the Cultural Informatics Research Group at the University of Brighton, UK where she got involved with additive manufacturing within the context of cultural heritage applications. Since then her research is focused on developing cellular structures for additive manufacturing. Dr Medeiros e Sá has organised the last 3 editions of the workshop on Interactive Data Visualization ( and was chair for the XXVII Conference on Graphics, Patterns and Images (SIBGRAPI 2014). She also led the Reshaping History exhibition and workshop in Rio de Janeiro in 2014 (
