Other Activities

Speedsolving

I am a speedcuber, which means that I solve twisty puzzles against the clock - competing against others and myself. For example, it takes me around ten seconds to solve the well-known Rubik's Cube or three seconds to solve a puzzle called "Skewb". Solving puzzles and learning new strategies play an important role, but there are various related activities. For example, I'm an experienced content creator, and even before uploading on youtube, I started producing tutorials for gutefrage.net over a decade ago. Some more recent videos can be found in the box below, showing my currently favourite puzzles in action.

Volunteer work

Member of the World Cube Association (WCA). Served in various roles, e.g. as Community Representative for the WCA Advisory Council, Delegate, (Lead) Organizer, Translator, Open Source Contributor.

Competitive speedcuber

Competed in fourteen countries, including the European Championship 2018 (Madrid) and 2022 (Copenhagen).

34 official podiums (4x gold, 14x silver, 16x bronze) out of 94 tournaments, obtained in categories "3x3x3", "Skewb", "4x4x4", "6x6x6" and "7x7x7". Female National Record holder in category "Skewb", and first place at German Online Cubing 2020, the "official" replacement of the National Championship in an online-format during the global pandemic.

Usually, I combine the competitive aspect with creation of tools that assist with the training. An example is the development of open-source training software to practice solution strategies in the speedcubing category Skewb, called "SkewbSkills" (GUI application with Python plus Web solution with HTML, CSS, JS).

Outreach, Projects

Interviewee for

Initiated and gave a workshop on the Rubik's Cube (talk, tutorial) during the 2022 Annual Retreat of our Research Training Group, for PhD Students and PIs: Contribution (restricted access). A couple years earlier, when still in school, taught fifth to twelfth graders how to solve the cube in a school project. Additionally, I built software and created some content (print + web) that targets new competitors. Further projects for the community were a novel team-based tournament format with federal-state rankings that attracted a large audience.

Content creation: educational resources for twisty puzzle enthusiasts (mainly YouTube, Instagram), focus: tutorials, explaining solution strategies with which thousands of people have learnt something new. Coaching new cubers through various channels, created material for a (German) online course on advanced methods for the brainteaser "Skewb".

Affiliated with cuboss.com ("brand ambassador" promoting their services and products on social media), previous cooperations with other sellers of twisty puzzles.

Cooperation with "C.H. Beck" (book review: Beleglink).
