Area of Expertise Überblick

Since 2011, I have been building elaborate Web applications, including interactive software visualizations, physics simulations, and full-fledged integrated development environments. Through this work, I acquire an in-depth understanding of various Web technologies and a diverse arsenal of tools, techniques, and workflows to solve problems. Further, I am a strong advocate for continuously improving and adapting the tools I work with, applying this philosophy to input devices, editors, programming systems and languages. As a researcher, I designed, implemented and evaluated programming tools and language extensions, with a focus on live and exploratory programming, reactive programming, and dynamic program adaptation.

Lively4

79 people, 9 years
Lively4 is a web-based development environment and application platform. It is self-sustaining and live in that applications and tools to create them exist in one environment. Both can be adapted while being used. Lively4's community embraces a wiki-like spirit, meaning everybody is encouraged to change aspects of Lively4 to suit their needs and share their adaptations with others.

Designed core features of Lively4 and contributed to the inital version, supervising a team of 10 people
Oversaw numerous teams of master students working on various applications in or core aspects of Lively4
Co-maintained the project for over 9 years

Demo Code Paper

Active Expressions

18 people, 8 years
Active Expressions allow developers to react to changes in any object-oriented expression in state-of-the-art languages. In contrast to most reactive programming concepts, Active Expressions leverage the existing expressiveness of the host language and builds upon it: Developers use ordinary variables, properties, and expressions to specify dependencies.

Designed core aspects of Active Expressions and implemented multiple versions in JavaScript
Oversaw 4 teams of master students to work on other implementations in Python, Squeak/Smalltalk, and JavaScript
Supervised 12 Students to work on supporting technologies, including debugging tools, editor watch integrations, and graphical connectors

Demo Code Paper

Plugin Explorer and Debugger

5 people, 2 years
The Plugin Explorer is a live editor specifically designed towards the task of writing and adapting source code transformations, here babel.js plugins. Developers can explore and correlate input and output examples visually and apply instant changes. Further, a back-in-time debugger allows developers in inspect the entire transpilation of an example input.

Designed core features and workflows for the Plugin Explorer
Co-implemented and maintained the project
Supervised corresponding master students' projects

Demo Code

Floom

1 person, 2 years
Floom is an interactive fluid simulation, implementing the hybrid Material Point Method using both particles and a grid. Floom supports different computational models and multiple materials. On the fly, you can dynamically apply forces, add or remove particles, change material parameters, and even switch between models.

Designed and implemented the simulation, editing tools, and debug support

Demo Code

Pronto

13 people, 2 years
Pronto is a rapid prototyping tool for designing game mechnics based on the Godot game engine. Pronto fosters quick assembly of game logic by overlaying the game scene with visual behaviors. These behaviors can be connected using drag-and-drop interactions.

Co-designed core features of Pronto
Supervised 5 teams of master students to iteratively improve Pronto

Thema: Meine Doktorarbeit schlägt Active Expressions vor, eine Spracherweiterung, die Reaktivität zu modernen Programmiersprachen hinzufügt. Mit Active Expressions als neue Abstraktion zur Erkennung von Änderungen können Entwickler:innen von reaktiven Programmierkonzepten deren Integration in die Host-Sprache vereinfachen und sich darauf konzentrieren, wie auf Änderungen reagiert werden soll.Topic: In my thesis, I present Active Expressions, a language extension that adds reactive capabilities to state-of-the-art programming languages. Active Expressions provide a shared foundation for reactivity in object-oriented languages, allowing system developers to create novel reactive programming concepts without dealing with the technical necessities of change detection.
