He studied the use of wooden, brick, stone, and gypsum decorations, specifically in the building façade. His current research focuses on 3D simulation models and methods to combine artificial intelligence with heritage conservation. In his spare time, he extracted and classified the forgotten ancient words from ancient lexicon and texts, which led him to publish three books in this field.
