As a building physicist, I pioneer Bio-Intelligent Building Systems—an interdisciplinary approach that harnesses living materials, AI-driven design, biotechnology, vernacular design practices, and building physics to engineer passive, self-regulating structures for extreme climates, from arid deserts and polar outposts to space habitats. I integrate biomimetics, bioclimatic strategies, and time-tested vernacular techniques to create adaptive architectures that both mitigate and help cushion against climate change. With extensive expertise in engineered living material, such as Mycelium-based composites (MBC), Bacterial Cellulose and Microbially Induced Calcite Precipitation (MICP), bio-fabrication and characterisation, AI-driven design and bio-digital fabrication, and building systems instrumentation, prototyping, testing, and simulation, I advance active and passive cooling/heating, natural ventilation, and daylight optimisation, pushing the frontiers of sustainable, circular, net-zero building technologies.
