Visual Computing

Chris Wojtan heads the Computer Graphics and Physics Simulation group at ISTA. He and his group develop geometric and numerical algorithms for computer animation and geometry processing and try to find new efficient and robust ways to simulate solid and fluid dynamics, control physics simulations, and compute with 3D shapes.

Mickaël obtained his PhD at Inria Grenoble-Rhône Alpes in the Elan team under the supervision of Florence Bertails-Descoubes and Mélina Skouras, researching the direct simulation and inverse design of garments in the presence of frictional contact. Currently, he works on the representation of signals on moving surfaces.

Yi-Lu is a PhD student at ISTA, supervised by Chris Wojtan. He researches algorithms for the simulation of rigid body dynamics in the presence of frictional contacts and shock propoagation, as well as the simulation of granular materials.

Sadashige researches mathematics, physics, and also computer simulation of natural phenomena. He is especially interested in exploring the dynamics and the geometry that fluids can exhibit from viewpoints of geometric mechanics (symplectic, Poisson, and contact geometry) and optimal transport.

Mau is a PhD student at ISTA, co-affiliated with Chris Wojtan and Andela Šarić. In his research, hemodels the morphology of biomembranes using triangulated meshes.

Peter is a PhD student at ISTA, supervised by Chris Wojtan. He researches how to robustly handle topological changes on non-manifold moving meshes.

Evgeny is a PhD student at ISTA and is currently working on water-wave simulation with geometrical optics.

Christian did his PhD in computational design and digital fabrication under the supervision of Bernd Bickel’s group at ISTA. In his research, he tries to find out how the physical limits of mechanical systems can be described geometrically. He is now the research software engineer in Chris Wojtan’s group.

Ihor is an intern in the Wojtan group, and works on the simulation of crack formation and propagation in complex materials.

Physics-Based Simulation

I am now a researcher in the MFX Team at Inria Nancy in France (https://mfx.loria.fr/). I was a postdoc researcher at IST Austria in Chris Wojtan Group between 2016 and 2020. I am interested in physics-based simulation and modeling natural phenoma as well as geometric modeling. I obtained my PhD in 2016 at the University of Grenoble-Alpes, supervised by Stefanie Hahmann and Damien Rohmer of the Imagine Team. I got an Engenieering Degree in 2013 from the school ENSIMAG (Grenoble INP) of Grenoble, France.

I got my MSc in Computer Science in 2009 from the Jagiellonian University in Cracow, Poland. Then I obtained a PhD in 2015 at the AGH University of Science and Technology in Cracow. Currently I am a postdoc researcher in Chris Wojtan’s group. My research interests include physics-based simulations, multiobjective optimization and evolutionary algorithms.

I got my B.Sc. in Physics from the University of Tokyo, and I’m now a master student in computer graphics under the supervision of Takeo Igarashi (expecting M.Sc. in Computer Science in March, 2017). I was mainly working on virtual reality and fluid simulation so far. My current research interests are physics-based simulation, computer vision and applied math.

I’m a PhD student in Chris Wojtan’s group mostly working on simulations of brittle fracture. I’ve previously studied simulation engineering at St. Pölten University of Applied Sciences.

I got my M.Sc. in 2001 and a Ph.D. in 2005, both in computer science from the University of Rostock, Germany. Afterwards, I spent several years as a post doc researcher in projects at Vienna University of Technology, Arizona State University and IST Austria. My research interest includes modeling and display of vectorized image representations, applications and solvers for PDEs, as well as modeling and rendering complex natural phenomena, preferably in real time.
