Yan Zhang ‘Ryan’ is a Ph.D. researcher in City Science research group at the MIT Media Lab. He is developing and deploying CityScope – an A.I. enabled urban decision support system, which aims to democratize the urban decision-making process in an early stage. This dynamic Lego city model gives people the right tools to understand and participate the urban design intuitively. His research work also includes a variety of interdisciplinary projects focusing on data visualization, optimization, complex geometry, machine learning, etc. Ryan has a background in architecture design with a particular emphasis on computational design for more than ten years.
