Paul has 28 years of experience specializing in the characterization and assessment of hydrogeologic systems to understand groundwater flow and contaminant transport. Mr. Martin is an experienced MODFLOW and FEFLOW user, having applied these tools on several hundred projects. Through these projects as well as through teaching numerous modeling short courses, he has gained a wealth of experience in the practical application of modelling, database and GIS tools. Recognizing the role of numerical models as decision making tools, he has developed expertise in their application, including the incorporation of detailed hydrogeologic structure, and uncertainty quantification. His reputation has been developed through numerous publications and is demonstrated by his appointment as a keynote speaker at a recent modelling-focused conference (FEFLOW 2018).
