# CV (Curriculum Vitae)

## Current

Since 2012 I have been running my business called MO-Labs. I create mathematical sculptures and other mathematical objects such as mathematical models, mathematical illustrations, interactive illustrations, mathematical software, websites, etc. Moreover, I give talks about historical and modern math objects. Another focus is the creation of math-related exhibitions.

Although I am not affiliated to any university, I frequently teach at different universities.

For my math objects, math research, math teaching, and math talks, please see the other sections of this website.

## Interests

As you may see from the positions mentioned below,

- my first research focus was
**algebraic geometry with computational and historical aspects**, about 1999-now (still now as part of my business), - then
**applications**of this**to computer science and architecture**, with a focus on geometric modeling, about 2006-now (still now as part of my business), - then
**applications**of this**to math didactics**, about 2009-now (still now as part of my business), - and finally
**applications**of this**to the history of mathematics**with a focus on 19th century mathematics, in particular mathematical 3d-models created during this period, about 2003-now (still now as part of my business).

In my **business MO-Labs** I am now combining all of these diverse backgrounds: higher geometry (not only algebraic, but also differential, discrete, etc.) for creating abstract math objects, geometric modeling for realizing them as a 3d data set, math didactics because I need to know which objects may be used for teaching, and math history because I need to know which objects have a history and how I should incorporate this in my own creations.

## Positions
