# Marc Kimmel > Personal website of Marc Kimmel, research assistant for process engineering and process mining at the Professorship for Concurrent Systems of the University of Augsburg, and software engineer. It presents his research and publications and hosts free games (two of them played outdoors with a phone) with their complete rules, a Petri-net editor and interactive computer science explanations. Every page exists in German (the default, without prefix) and in English (under /en). Every link to a page of this site points to its Markdown version: append `.md` to any page address, the home page is `/index.md` (German) and `/en/index.md` (English). The HTML page is the same address without `.md`. Last content change: 2026-10-11. Contact: support@marckimmel.de. Location: Augsburg, Germany. Areas with many pages have their own index: games at https://marckimmel.de/spiele/llms.txt and computer science at https://marckimmel.de/informatik/llms.txt. The text of all pages in English is at https://marckimmel.de/llms-full.txt. ## About and research - [Marc Kimmel, home page](https://marckimmel.de/en/index.md): Research (process-centric objects, empirical understandability of process models, Petri nets), teaching, publications, projects and sport. - [Process Mining](https://marckimmel.de/en/process-mining.md): Process mining on marckimmel.de: model, simulate and export Petri nets directly in the browser.
