Donghoon Yang is a research scientist at the Digital Building Laboratory in the Georgia Institute of Technology and previously worked as a researcher at SK Engineering and Construction, South Korea and Skidmore, Owings and Merrill, NY. His main research topic is in the area of interoperability in the AEC/FM industries, which enables others to reuse the once generated information without losing any design intents. His work on interoperability includes specification of open standards for data exchange, implementation of software tools for importing and exporting, and validation of exchanged information. His other researches include expert system on architectural design, parametric modeling and form generation, digital fabrication, and construction methods for structural building elements. He was the instructor for Parametric Modeling courses, and a co-instructor for the Building Data Modeling course with Professor Charles Eastman.
