Researcher in Spatial Statistics and Environmetrics
Inspired by the time-series ARCH model developed by Robert F. Engle (1982), for which he was awarded the Nobel Prize, we have introduced a univariate spatial ARCH model in 2016 (first published arXiv paper).

Description of my R-package for simulation and estimation of spatial GARCH models, including a new logarithmic spatial ARCH process.
Functional geostatistical analysis of bike-sharing usage in the capital of Finland, Helsinki.
We propose an adaptive LASSO estimation procedure to fully recover the unknown weight matrix of spatial autoregressive panels with locally varying mean levels.

Statistician and data scientist with strong interest in environmental sciene
I am currently an assistant professor of Big Geospatial Data at the Leibniz University Hannover (Institute of Cartography and Geoinformatics). For one year, in 2020-2021, I was the interim professor of Spatial Data Analysis and Statistical Learning at the University of Göttingen. Before that, I led the junior research group Detection and Surveillance of Spatial and Spatiotemporal Clusters at the Viadrina Center B/ORDERS IN MOTION at the European University in Frankfurt (Oder), where I also did my Ph.D. in statistics in 2016.
In my main research area (topic T.10087 "Maximum Likelihood Method, Panel Data Model, Spatial Econometrics"), I am currently ranked 23rd worldwide on Scopus and 1st among German researchers (rated as top 8% scientists with their first publication in 2016 on ResearchGate, across all disciplines).
Below I update from time to time some news from my research, my externally funded projects and teaching.
Do you prefer cycling uphill or downhill in the rain? Or not at all? The paper deals with the functional statistical analysis of the usage of the bike-sharing service in Helsinki. It fully accounts for temporal, spatial and spatiotemporal interactions.
The paper is availabe open-access in the Journal of the Royal Statistical Society Series A (DOI)
I am looking for new research assistants (PhD students) for the project "Time series analysis of historical maps". The project deals with statistical modelling of geo-referenced time series from historical maps, mainly generalised additive models.
If you are interested, please feel free to contact me by email (attaching your current CV and references, such as papers, theses, etc., if available).
Inspired by the concept of Johannssen, A., N. Chukhrova, F. Schmal and K. Stabenow (2021): Statistical Literacy – Misuse of Statistics and its Consequences (Journal of Statistics and Data Science Education, 29(1), pp. 54–62.), I now teach my seminar on "Monitoring of Spatiotemporal and Network Data" in a research format, including writing a small scientific paper, double-blind peer reviews, revision process and colloquium presentation.
