Shiny: Book value analysis
I'm currently (Aug 2025) learning Shiny in R. View my progress on this project in which I analyze the books I read since Oct 2023 and how much money I spent on them and create plotly plots for them.
Portfolio
I have worked on a number of different projects throughout my career, a selection of which is presented here.
Data Science: Personal projects
These are projects I created for fun and/or in order to learn or expand my knowledge on the technologies used.
Roleplaying Community Survey
As an organizer of the bi-monthly English-speaking Roleplaying Jam in Düsseldorf, I was curious about the demographics of this community and their language preferences when it comes to roleplaying. I ran a survey using SoSciSurvey and analyzed the data using R, creating ggplots.
Analyzing Doctor Who (2005) Viewership with ggplots
As a long time viewer of Doctor Who (2005), I was curious about the decline in quality of the show. In order to visualize this decline, I created ggplots in R of the IMDb ratings and UK viewership numbers of the show's Seasons 1 through 13, taking into account factors such as showrunner, Doctor and companions.
Robin Hobb Book and Reading Speed Analysis
After I finished reading a 16-book series by author Robin Hobb, I was interested in my own personal reading speed, so I analyzed the lengths of these books and came up with my own measure to analyze my reading speed based on book length, plotted in plotly.js.
Data Science: Academic Research
These are projects I worked on during my time in academia. Most are part of my PhD project.
Paradigm uniformity in inflectional stems
My dissertation contains 5 different projects related to paradigm uniformity effects (see other projects on this site for details), and was published as a 168+ page book by düsseldorf university press.
Comprehension experiment using mousetracking
I conducted a mousetracking experiment to investigate whether listeners can perceive acoustic differences in words spliced from segments of word pairs like days and daze. Details of this study are available in Chapter 6.2 of my dissertation.
Same different experiment
This experiment investigated whether participants can hear an acoustic differences between stems of words (e.g. day in days) and artificially lengthened versions of these stems. Details of this study are available in Chapter 6.1 of my dissertation.
Production experiment
This experiment elicited target items by means of a cloze task. The target items were late analyzed under the assumption that there would be durational differences between monomorphemic and complex words. Details of this study are available in Chapter 5 of my dissertation.
Paradigm uniformity: QuakeBox Corpus Study
My published paper Phonetic reduction and paradigm uniformity effects in spontaneous speech investigates durational differences in homophonous monomorphemic and complex word pairs, using data from the QuakeBox corpus. I later replicated this study with the Buckeye Corpus (see Chapter 4.3 of my dissertation).
'Mate' in Australian English
Inspired by my semester abroad in Australia, I examined the gender restrictions of the address term 'mate' in Australian English. I conducted a survey study in 2016, which I replicated and expanded in 2022. It is scheduled to be published as In Australia, can anyone be your ‘mate’? - Gender restrictions of the address term ‘mate’ in Australian English.
Miscellaneous projects
These projects are mostly the result of my hobbies.
Düsselgamers
I've been managing the Düsselgamers community since 2016. Originally the Düsseldorf Boardgamers Meetup Group, it has expanded beyond board games and is a large and vibrant community of all types of in-person games. Aside from managing the website, discord and public relations, I also organize the bi-monthly Roleplaying Jam event.
Player Aids for Board Games
Creating player aids for board games is a hobby of mine, which has taught me valueable skills - first and foremost in the usage of InDesign, but also in the field of UX writing, as writing texts concisely and comprehensively on such limited space is quite a challenge.
chaosworks.org - Personal Blog
I have had personal websites for over 20 years, and these got me into coding and web design. Since quitting most social media, I tend to blog more again - mostly my thoughts about media that I consume.
