Daniel G. AliagaAssociate Professor of Computer Science, Purdue UniversityEducation: Daniel Aliaga holds BS in Computer Science, honors thesis (with Andy van Dam) and magna cum laude, from Brown University. Subsequently, obtained a MS (with Henry Fuchs) and a PhD degree (with Anselmo Lastra, Fred Brooks, and Dinesh Manocha) in Computer Science from UNC Chapel Hill. Worked at Nokia/Lucent/AT\&&T Bell Labs (with Ingrid Carlbom) and at Princeton University as a researcher (with Tom Funkhouser). He joined Purdue in 2003, co-founding the Computer Graphics and Visualization Laboratory (CGVLAB). Dr. Aliaga has held visiting professor positions at ETH Zurich Information Architecture and also ETH Computer Science, INRIA Sophia-Antipolis, and KAUST in Saudi Arabia. After finishing high school (Colegio Santa Maria), Daniel immigrated from Lima, Peru and is the first in his family and relatives to hold a PhD. Products: Dr. Aliaga's first computer graphics publication was in 1991 and he now has over 160 refereed publications covering multiple disciplines, holds membership in 90+ program committees, has on-going international multi-disciplinary collaborations (i.e., with computer science, urban planning, architecture, meteorology, atmospheric/earth sciences, engineering, archaeology, and more), and has given over 50 invited talks (in the US, Brasil, Colombia, Ecuador, France, Japan, Korea, Peru, Qatar, Sweden, and Switzerland; TEDx). Further, Dr. Aliaga has been technical advisor on multiple startups (Synthicity, UrbanSim, Authentise). Funding: Prof. Aliaga has obtained 29 external peer-reviewed grants totaling over $42M (and is PI on 22 of them). Funding sources include NSF, IARPA, USDA, Internet2, MTC, Google, Microsoft, and Adobe. Service and Awards: Daniel is Associate Editor for IEEE TVCG and for Visual Computing Journal (previously for Computer Graphics Forum and Graphical Models) and PC member for SIGGRAPH, CVPR, ICCV, Eurographics, AAAI, I3D, IEEE Vis. He has received a Fulbright Scholar Award, a Discovery Park Faculty Research Fellowship, and his PhD advisees have received a total of 11 Purdue fellowships/grants. He is a member of ACM SIGGRAPH and ACM SIGGRAPH Pioneers, and has multiple times been Chair of Faculty Diversity for College of Science at Purdue. |

Teaching
Urban Visual Computing

Dr. Aliaga pursues visual computing for modeling and improving the complex urban ecosystem. His work develops semi-automatic and automatic algorithms for controllable content creation and edition of large and complex geometric models for use in urban digital twins, simulation, visualization, entertainment, education, and cultural heritage. His methodologies generally convert incomplete and unstructured data into organized and easily editable procedural representations. While a significant benefit of procedural modeling is its detail amplification, it is very difficult to develop a compact, expressive, and editable set of procedural rules. His research group has innovated various forms of generative modeling, urban artificial intelligence, and optimization to infer procedural rules and parameter, graphs and layouts, 3D models, images, sketches, point clouds, roads, facades, buildings, cities, and vegetation. In addition, he has developed multiple novel image processing, 3D reconstruction methods, 3D spatial augmented reality, camera calibration, and computational display solutions. Further, Dr. Aliaga leads and participates in numerous computational urban projects in city gray and green planning, atmospheric/geological sciences, civil engineering, architecture, and transportation engineering to capture, simulate, and modify models of current and future urban environments. |
