Carol O'Sullivan is the Professor of Visual Computing in Trinity College Dublin, where she leads the Graphics, Vision and Visualisation (GV2) research group. She joined TCD as a lecturer in 1997 and served as the Dean of Graduate Studies from Jul'2007 to Jul'2010. Her research interests include graphics and perception, Computer Animation, Crowd and Human simulation. She has managed a range of projects with significant budgets during that time and successfully supervised many doctoral and post-doctoral researchers. She has been a member of many international program committees, reviewer for various journals, and a senior reviewer for the annual SIGGRAPH and Eurographics conferences. She has organised and co-chaired several conferences and workshops, including the SIGGRAPH/Eurographics campfire on Perceptually Adaptive graphics, Utah 2001, the annual Eurographics conference in 2005 and the ACM Symposium on Computer Animation in 2006. Prior to her PhD studies, she spent several years in industry working in Software Development. She was elected a fellow of Trinity College for significant research achievement in 2003 and of the European Association for Computer Graphics (Eurographics) in 2007.

Research Projects
Project title Metropolis
Summary The Metropolis project is a novel interdisciplinary project combining computer graphics, engineering and cognitive neuroscience research. Trinity College researchers Prof. Carol O’Sullivan and Dr. Steven Collins from Computer Science together with Dr. Fiona Newell from the Institute of Neuroscience and Prof. Henry Rice from Mechanical Engineering will apply principles of human multisensory perception to create the most realistic, scalable and large-scale simulations of populated cities ever realised. The aim of the research is to simulate large crowds consisting of millions of people and to introduce a high level of variety in animation, appearance and sound, inspired by perceptual models and metrics. Real meaning will be added to the simulations by endowing individual crowd members with appropriate, sentient behaviours that are based on cognitive and sociological models. Furthermore, realistic populace and traffic noise will be simulated, effectively propagated depending on environmental factors, and driven by psychoacoustic principles. The project will build upon TCD’s ongoing Virtual Dublin project. The effectiveness of this research will be demonstrated in the areas of games (thereby contributing to the growth of an emergent entertainment industry in Ireland), environmental impact statements (EIS) for improved planning, and outreach activities to create assistive technology for disabled children.

Project title GUILD: Generating Urban Infrastructures from LiDAR Data
Summary This project involves automating the generation of three-dimensional computer models from aerial flyover data. LiDAR is a radar-based, laser scanning system, which can provide the technological under-pinnings to create automated three-dimensional Finite Element Modelling (FEM) meshes. The project leverages substantial previous investment in the form of the Virtual Dublin project.

Project title Evaluation and Perception of motion graphs
Summary Realistic and directable humanlike characters are an ongoing goal in animation. Motion graph data structures hold much promise for achieving this goal; however, the quality of the results obtainable from a motion graph may not be easy to predict from its input motion clips. With post-doctoral researcher, Paul Reitsma, we are building on his PhD work (conducted in Carnegie Mellon University) to evaluate and improve the quality of human motion using perceptual and task-based metrics.
