Hi there, I'm Egor Kotov 👋

I am a Spatial Data Scientist and Doctoral Researcher at the Max Planck Institute for Demographic Research (MPIDR) and Sociodemography Research Group at Universitat Pompeu Fabra (UPF). I also serve as a computation and reproducibility co-editor at the Population Dynamics Lab.

I analyse spatial digital trace data to study human mobility patterns and the implications for disease dynamics and inequalities.

📦 Selected R Packages and Software

{spanishoddata}

Access Spanish origin-destination matrices. Co-developed with Robin Lovelace, this package provides access to aggregated mobile phone-based human mobility data. It has been featured on the official website of the Ministry of Transport and Sustainable Mobility of Spain.

{rJavaEnv}

Java environment management for R. A package to manage Java environments for Java-dependent R packages in an {renv}-like manner. It serves as a companion to {r5r} and other Java-heavy tools to ensure reproducibility.

{rdocdump}

Prepare R package docs to feed to LLMs. A utility package to dump source code, documentation, and vignettes of R packages into plain text formats optimized for feeding into Large Language Models (LLMs).

{r5rgui}

Interactive routing explorer. A Shiny-based GUI to interactively explore routes calculated with the {r5r} package. Useful for troubleshooting routing problems and visualizing accessibility flows.

{ducksf}

Faster spatial processing with DuckDB. Work-in-progress. Leverages the DuckDB backend for high-speed spatial processing in R. Early results show areal-weighted interpolation performing 9-30x faster than standard {sf}/{areal} methods.

{gridmaker}

Spatial Grid Tools. A toolset for generating and managing spatial grids for demographic and mobility analysis.

• Other contributions: {mapineqr} (Inequality indicators API), {wikimapR} (Wikimapia API), and contributions to rang, layer, geofacet, and esri2sf.
