Phillip C. Reiner (b. 1981, Salzburg, Austria) is a trained architect, artist, and researcher working at the intersection of geometry, art, and technology. He studied at Technical University Berlin, Berlin University of the Arts (UdK), and completed his architecture degree at University of Applied Arts Vienna under Studio Prix.

From 2010 to 2022, he worked in the studio of Danish-Icelandic artist Olafur Elíasson, where he established and led the Advanced Geometries Department (AID). During this period, he developed methods for geometric interpretation that translated mathematical concepts into physical models and artistic installations. His work bridged computational design, fabrication processes, and spatial perception, contributing to large-scale installations and exhibitions worldwide.

In 2023, he founded protoCtrl in Berlin, an independent collaborative research platform that explores geometric, physical, and natural phenomena for artistic concept development. The platform functions as an interdisciplinary investigation space, combining computational methods, material research, and artistic practice.

His research focuses on the translation of mathematical structures into tangible forms, examining how geometric principles generate new modes of spatial experience. This includes work with polyhedral geometries, spherical tessellations, scanning technologies, and parametric systems. Through collaborations with artists, scientists, and institutions, he develops projects that range from conceptual research studies to site-specific installations.

Reiner’s practice combines technical precision with artistic inquiry, maintaining a rigorous approach to both computational workflows and material realization. His projects have been exhibited internationally and continue to explore the relationship between abstract geometric concepts and their physical manifestation.
