Patrick Kastner is a researcher and educator specializing in environmental performance simulation and decarbonization of buildings and cities, and directs the Sustainable Urban Systems Lab at Georgia Tech. He is an Assistant Professor at the School of Architecture and holds a courtesy appointment with the H. Milton Stewart School of Industrial and Systems Engineering.

His goal is to empower urban decision-makers with software tools that place sustainability at the forefront of the profession. He leads a Vertically Integrated Project titled Surrogate Modeling for Urban Regeneration (SMUR), which attracts a diverse group of students ranging from sophomore to graduate level, representing various engineering disciplines and other related fields across Georgia Tech.

He earned his Ph.D. and M.S. in Systems Science and Engineering from Cornell University in 2022. During his doctoral research, he developed Eddy3D, a microclimate modeling software toolkit for Rhino & Grasshopper, now adopted by leading institutions in both academia and practice. He previously taught at Cornell and UPenn.

Originally from Germany, Kastner holds an M.S. in Sustainable Building Science from TU Munich, and a B.S. in Energy Engineering from FAU Erlangen-Nuremberg. While in Munich, he was fortunate enough to study at the Center for Digital Technology and Management and enjoyed his time leading the operations team at TEDxTUM.
