Scientific Fields of Interest |
|
| Cosmology |
|
| In my three years at university I have been working on the Relativistic Generalization of Lagrangian Perturbation Theory under PD Thomas Buchert. To achieve that goal I rewrote the Einstein equations in the (3+1)-split using Cartan's co-frame as the single dynamical variable. A paper on the relativistic Zel'dovich-approximation as a special case of relativistic Lagrangian perturbation theory is in preparation. |

| Statistical Physics |
|
| In three dimensions there are four morphological measures, the Minkowski functionals, which describe the topological properties of a structure completely. Together with Professor Herbert Wagner and PD Thomas Buchert I investigated the statistical properties of large scale structure in the universe. We computed the Minkowski functionals of (volume-limited) galaxy samples provided by modern redshift surveys like the 2dFGRS and the SDSS. In that context we wrote a code, called SAHA, which computes the four functionals for a given point data set by means of the Boolean grain model. In that model we equip each point in the sample with a sphere of variable radius r. This radius serves as diagnostic parameter. We then calculate the functionals for each of the radii. Since Minkowski functionals are a robust measure and have great discriminatory power, we are able to distinguish between different models this way as well as look for non-Gaussianity in the initial fluctuations of large scale structure formation. |

The Sommerfeld Edition |
|
| The German theoretical physicist Arnold Sommerfeld (December 5, 1868 - April 26, 1951) pioneered developments in atomic and quantum physics, he for example introduced the fine-structure constant into quantum mechanics. However, Sommerfeld was particularly famous for his teaching, and for his "discovery and development of talents" (Max Born). During his 32 years as a professor in Munich he taught no less then six Nobel Prize winners and many other famous physicists. Very recently, the Chairs of Theoretical Physics at the Ludwig-Maximilians University Munich founded the Arnold-Sommerfeld Center for Theoretical Physics in his honour.
During the time as a student I had the pleasure to assist Michael Eckert and Karl Märker working on an edition of the scientific correspondence of Arnold Sommerfeld which provides fascinating insights into the development of theoretical physics from its very start. The edition consists of two volumes published by GNT, which can be found here and here, as well as an online source. |

My Own Teaching Career |
|
| Deeply impressed by the achievements of Arnold Sommerfeld as a teacher (see above), I soon realized that that would be my path in life. However, I decided to cultivate students interest in science at an even younger age and become a grammar school teacher. After two years of traineeship I now teach physics, mathematics, and computer sciences at the Oskar-Maria-Graf-Gymnasium Neufahrn b. Freising. |
