Professor Thomas Spiegelhalter is a German-US architect, engineer and urban planner. He has performed design and built research in Europe, the Americas, Asia, Africa, and the U.S. on numerous solar, carbon-neutral, zero-fossil-energy, and passive architectural projects; large-scale master planning and post-industrial infrastructures, landscapes, and engineered suspension bridges. As a result of his 34 years of awarded designs and built work, consulting, research, and teaching, Spiegelhalter has received 54 prizes, awards, and honours in competitions individually and in collaboration with engineers. His research work as a Professor at FIU involves geospatial and climatic data repositories with AI-ML-data-driven generative design workflows, mostly BIM-Dynamo-Grasshopper coding with biomimetics. The current bio-inspired research (http://crunch.fiu.edu/) is focused on optimized carbon-positive building and city design and planning scenarios towards carbon neutrality on a timeline from 2018 to 2100. Spiegelhalter has participated twice at the Venice Architecture Biennale, taught at several universities, and held visiting professor positions at institutions worldwide. He is the Global Visiting Professor at Keio University in Tokyo, Japan, from May 2023 to May 2024.
