Bio
I am now an Assistant Professor at the Institute of Science and Technology Austria (IST Austria). I received a PhD in Computer Science from the Georgia Institute of Technology, under the guidance of Professor Greg Turk.
I am currently accepting applications for new PhD students and Post-Docs.
- All research is performed in English.
- If you are interested in joining my research group as a PhD student,
please apply to be a graduate student at IST Austria. - If you are interested in becoming a post-doc researcher in my group,
please email me directly (wojtan at ist.ac.at).
Research Summary
I develop geometric and numerical algorithms for computer animation. My latest research couples high resolution embedded surface geometry to low resolution simulations in order to efficiently simulate detailed animations of elastic, plastic, and fluid phenomena. I have additionally designed methods for computing topological changes with mesh-based surface geometry, researched various methods for optimally controlling large physics simulations, and devised schemes for coupling solids and fluids within a simulation.
