About us

REDΙ has a wide international network in both practice and academia that can ensure the successful delivery of resource-demanding projects.

WHO WE ARE

REDΙ was founded by Dr. Elias Paraskevopoulos (Administrator), Dr. Sotiria Stefanidou and Dr. Olga Markogiannaki to unite their strong skills and experience into a promising firm as an outcome of many years of collaboration in both professional and research activities.

We currently operate with a multi-disciplinary group of experts to provide high-end structural design, rehabilitation and consultation for built assets, engineering software tools, digital innovation and research services for the enhancement of built assets’ sustainability in a multiple hazard environment.

Taking advantage of the available resources, cutting edge scientific knowledge and professional experience, we create added value for our clients by implementing integrated approaches to arrive to state-of the art solutions.
