my previous research topics

To give you an overview about my scientific background, I just want to list a few of my research areas and projects performed during my study. The talks where also held during my study, they are all in german, but they may be interesting for some people.

PhD-Thesis and other projects during this period

Statistical analysis of biomedical data - I will focus on the theory and the applications of data analysis tools to biomedical data, using for example the Independent Component Analysis (ICA) - a method used for the Blind Source Separation (BSS) problem - and other methodes as for example time series analysis and random matrix theory (RMT). Furthermore models for biomdeical systems are derived and investigated.

Granular material - simulation of granular material with a hard sphere model. Goal of this research is to understand the behaviour of the granular material under different gravitational forces (zero-g or micro gravity, 1g and hyper gravity).


Master-Thesis and projects during my study:

Ground Penetrating Radar (GPR) - my master thesis. An electromagnetic method used in geophysics to map the subsurface. Main aspects were the radiation patterns of dipole antennas.

Atompack - calculation of packing densities of amorphous metals with more then two components.
Hotzenplotz - a microgravity experiment for the student parabolic flight campaign (SPFC) from ESA, designed at the Institute for Geophysics (Technical University of Braunschweig, Germany)


Some nice talks held by me during my physics study:

Bernoulli-Equation - in a seminar on hydrodynamics. Sorry, the slides are in german...
Jospehson-Effect - used in a superconducting device to compare voltages on 10-10 exact. Sorry, the slides are in german...
Lorenz-Attraktor - in chaotic systems. Sorry, only in german...


Patents:

Encrypted data transmission - a german patent (DE #4439032) on "Verfahren und Vorrichtung zur verschlüsselten Datenübertragung" from Andreas Jung and Klaus Schröder
