Andreas Theodoridis is a practicing architect-engineer and environmental technologist with a Ph.D. from the Center for Architecture Science and Ecology (CASE), a research center of Rensselaer Polytechnic Institute based in New York City, and a research collaborator at the Yale Center for Architecture Ecosystems (CEA). He holds a Diploma in Architecture and Engineering from the Aristotle University of Thessaloniki in Greece, and an M.S. in Sustainable Environmental Systems from Pratt Institute, where he was awarded the Green Infrastructure Fellowship and an award for outstanding merit. Theodoridis is the founder of United Atmospheres, an experimental design practice and consultancy based between New York and Athens.

His research is interdisciplinary, merging 25 years of experience in building construction and fabrication with applied research on building systems and environmental initiatives on an urban scale. His current work focuses on hybrid air phytoremediative modular ceramic systems for building envelopes, relative to questions of environmental inequality.

Theodoridis has taught at Syracuse University and Columbia University's Graduate School of Architecture, Planning and Preservation. He also lectured at the Syracuse Center for Excellence in Environmental and Energy Systems and served as a visiting researcher at the Cooper Union Institute for Sustainable Design. He is the recipient of awards and distinctions including the Humanities Graduate Fellowship at Rensselaer Polytechnic Institute, an honorable mention at the Architect's Newspaper Design Awards, the One Prize annual design and science award, as well as an honorable mention on the d3 Unbuilt Architectural Visions international competition.

His work has been exhibited and published in several architectural exhibitions and forums including the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Journal; Divergence in Architectural Research: ConCave, held at Georgia Tech; OFFRAMP Journal of the Southern California Institute of Architecture (SCI-Arc); the Venice Architecture Biennale; the Design Hub of Barcelona; the Oslo Architecture Triennale; the Le Lieu Unique Center for Contemporary Culture in France; the Istanbul Design Biennale; the Onassis Cultural Center in Greece; the Museum on the Seam in Israel; the Tallinn Architecture Biennale in Estonia; the University of Michigan; Princeton University; and the NYCx Design week, among other venues.
