His research has been instrumental in incorporating spatial dimensions into economic analysis through spatial econometrics, geocomputation, and increasingly artificial intelligence. As co-founder and Editor-in-Chief of the Journal of Geographical Systems since 1993, co-founder of Springer’s Advances in Spatial Science series, and co-editor of the Handbook of Regional Science (2021), he has helped shape the methodological development of regional science for more than three decades. His scholarly output comprises over 400 publications, including more than 260 peer-reviewed articles and chapters and 20 monographs, with an h-index of 51 and more than 11,000 citations. The five selected publications below—addressing spatial dependence in trade panels (Journal of Geographical Systems, 2020), regional housing responses to monetary policy (Real Estate Economics, 2019), Markov-switching factor-augmented VAR models (Oxford Bulletin of Economics and Statistics, 2018), spatial growth regressions (Spatial Economic Analysis, 2008), and rough-set classification of interval-valued information systems (International Journal of Approximate Reasoning, 2008)—reflect a career dedicated to strengthening the spatial analytical foundations of modern economics and connecting methodological innovation with empirical and policy applications.
