Short CV (updated: Feb. 2018)
I am an Associate Professor at Chalmers University of Technology, in Gothenburg (Sweden). My research interests are in the area of interactive computer graphics, physically-based animation and virtual characters synthesis, with application to computational design and medical fields. In particular, I focus on (i) the application of computational physical models to the simulation of soft bodies and (ii) the design and implementation of parallel simulation algorithms and data structures suitable for the full exploitation of modern GPUs. I have been a senior lecturer at Chalmers (2014 – 2016), and an assistant professor (2011 – 2014) at Sapienza University of Rome (Italy), where I obtained my PhD degree (2009) in Computer Engineering. I have been also a visiting professor (03-07/2014) at Télécom ParisTech in Paris (France), and from 2004 to 2006 a visiting researcher at the Image Coding Group at the Linköping Institute of Technology (Sweden).
Interactive deformable body dynamics is a largely studied field in 3D computer graphics because it allows to replicate the motion and the properties of soft objects like cloth, fabric, hair, skin, etc. This is extremely useful in a broad range of areas including CAD industry (virtual prototyping and visualization), media and entertainment (video games), education tools (for example, surgical simulators), and visual feedback in science and engineering. The animation of soft objects is difficult because they are defined by complex physical and mathematical models, which must be solved in few milliseconds to allow the real-time interaction with the user. Usually, the achieved dynamics look plausible but it is not realistic in a mechanical sense. Encompassing actual realism without sacrificing interactivity is one of the goals of my current research. See this video from the two minutes paper channel for a brief and clear explanation of my most recent work.
Virtual character animation is a difficult problem which has been studied by the Computer Graphics community from more than thirty year, with many application areas ranging from entertainment to telepresence. The human body is composed by many heterogeneous components tightly interconnected together. The tissues are formed by anisotropic, incompressible materials, whose dynamic behavior is hard to replicate. The problem requires precise solutions because we, as human beings, are trained to detect the smallest artifacts. I developed several approaches which carefully crafted (in a numerical sense) the different properties of the human tissue and combine them together seamlessly. I have obtained relatively simple models of the human face, governed by few parameters and thus easy to use, but still able to produce convincing and believable results.
