# Recent Projects

## gwpv

A **visualization code for gravitational wave data** I created **in 2020**.

This Python package uses the ParaView scientific visualization toolkit to produce 3D renderings of gravitational wave data from a numerical simulation or a waveform model.

## Gravitational waves playground

An **interactive iPad visualization** I created **in 2018**.

In this Swift playground book you can make gravitational waves visible and control the visualization of this elusive radiation emitted by two inspiraling and merging black holes.

## Black holes playground

A **series of interactive iPad simulations** I created **in 2017**.

In this Swift playground book you’ll explore the physics of black holes in Albert Einstein’s theory of general relativity with three interactive simulations on your iPad. Discover the possible trajectories of test particles around a Schwarzschild source, explore the optical effects that occur when a massive object lenses a background light source and watch two black holes merge to hear the gravitational waves they produce in the process.

## Python Introductory Course

An **online course** I created **in 2016** for **Heidelberg University**.

This course gives an introduction to scientific programming with Python for first-year physics students beginning their lab course at Heidelberg University.

## TexFig

A **vector plotting utility** I created **in 2016**.

This utility assists in producing vector plots with Python’s matplotlib plotting library for seamless typesetting in LaTeX documents.

## Heidelberg Map Print

A **map design** I created **in 2016**.

The design is based on Ian Villeda’s Wheatpaste style for Mapbox Studio. It shows a personal view on Heidelberg, highlighting university grounds, railway tracks and green spaces.

## LaTeX Flipbook

A **LaTeX package** I created **in 2015**.

Delight readers of your LaTeX document or thesis with a flipbook effect when they rapidly flick through the printed pages or the PDF.

## Evergreen

A **Swift logging framework** I created **in 2015**.

This framework allows developers to replace their `print`

logging by *Evergreen*’s versatile functions to dynamically adjust the verbosity of specific parts of their program, log to multiple destinations (such as files) with custom formatting and easily measure time. *Evergreen* logging is great to use in any Swift project, but particularly useful when developing a framework, since it gives its users granular control over the output the framework generates. *Evergreen* is inspired by Python’s excellent `logging`

module and architected for Swift.

## Lectures on iOS App Development

A **lecture series** I held **in 2015** at **Heidelberg University**.

The lecture *Software development for iOS* gives an introduction to modern application development with an integrated development environment (IDE), the object-oriented programming language Swift and the construction of user interfaces, exemplary for mobile apps on the iOS platform.
