I’m a spatial researcher and geodata scientist from Germany.

I graduated in 2006 from Ludwig-Maximilians-Universität (LMU) in Munich, Germany, in social geography/anthropogeography and geoinformation science (GIS) and received a doctoral degree from the Division of Spatial Information Science (SIS) at the University of Tsukuba (筑波大学) in Tsukuba, Japan, in 2014. My research is based on the use of GIS and spatial methodologies in analysis, visualization and simulation or modeling in order to gain deeper insights into the processes triggering human behavior.

My graduation thesis (German: “Diplomarbeit”) is titled “Spatial Modeling and Analysis of Man-Made Large-Scale Loss Events Using GIS” (German title: “Räumliche Modellierung und Analyse anthropogen bedingter Großschadenereignisse mit Hilfe eines Geographischen Informationssystems”), which I created in collaboration with Munich Re.

After graduation I have been working for a global GIS corporation for about 3.5 years before returning to academic work.

In my PhD thesis titled “Spatio-Temporal Analysis of Terrorism Vulnerability – A Case Study of Central Tokyo, Japan” I focused on the use of spatial methods for the assessment of threats, especially terrorism, in urban areas, specifically in Japanese cities. The scientific approach I used in my research is that of vulnerability analysis as opposed to risk analysis, which is more widely done in contemporary research. The approach to apply spatial methodology in the vulnerability analysis to terrorist threats is fairly new. I’m strongly convinced that socio-spatial factors and processes determine vulnerability and am led in my research by the hypothesis that vulnerability is closely related to the relative position in space of buildings, infrastructures or social groups at risk. I believe urban areas to be the most suitable study area, as this is where the aforementioned processes can be observed, measured and operationalized. The main target of my research is to put the approach of Spatial Urban Vulnerability Analysis on the agenda of both the spatial research and the hazard research community, as I believe that spatial methodology can further enhance vulnerability analysis.

After successfully finishing my PhD program in summer 2014 I started working as a research associate at the Institute for Transport Research at the German Aerospace Center (DLR) in Berlin, where I’ve been involved in the modeling of urban mobility and its bidirectional correlations with spatial structure.

Since March 2016 I returned to the commercial world, working as a Sales Consultant for Tableau – helping people see and understand their data. You can find some of the vizzes and presentations I crafted on my Tableau Public page. After the acquisition by Salesforce I continued my work with some of the largest customers in Germany, the DACH region, as well as Central & Easter Europe and the CIS. In late 2022 I worked for One Logic as Director for Strategic Product Management, helping to create a novel cloud-based Data Mesh enabling software platform.
