Forschung
In meiner Forschung konzentriere ich mich auf die Analyse von 2D/3D-Georadar-Daten in sedimentären Systemen, welche sowohl durch Modellierung als auch durch Akquisition im Feld generiert wurden. Klassischerweise werden solche Daten manuell und damit zeitaufwendig, subjektiv und selten reproduzierbar interpretiert. Ziel des Projektes ist es daher, zur Interpretation Datenattribute zu analysieren und zu klassifizieren, um 2D/3D Georadar-Faziesmodelle für den zu charakterisierenden sedimentären Untergrund zu generieren.
