My personal research interests in academia were mainly metallic foams produced by the liquid metal route (gas injection) as well as Al-alloys and metal-matrix-composites. I worked from 2010-2013 on my doctorate at the Helmholtz-Zentrum Berlin and defended in January 2014. During my thesis entitled "Investigation of metallic films as a model system of metallic foams", I demonstrated that the stabilisation of films, as imitates of foam cell walls, is based on particles and oxygen in combination, whereby the formation of a strong oxide surface of the cell wall cannot be relinquished to allow successful foam expansion. I also analysed and interpreted the rupture event of a single liquid Al-film by means of high-time resolute radioscopies acquired at the ESRF, Grenoble, France, using different image processing methods, see images left.

Afterwards, I worked as a postdoctoral research fellow at the Technical University Berlin and the "Institute of Structure and Properties of Materials" of Prof. Banhart under the guidance of Dr. Garcia-Moreno. All the results obtained by now led to several papers published in high-quality journals. Moreover, I presented my results in several international congresses dealing with foams and colloids (MMC). In my postdoctoral research position at the Technical University in Berlin, I studied the feasible foamability of liquid particle-free Al-alloys in-situ by means of X-rays and ex-situ using metallography and microscopy.

In August 2016 I decided to leave science and academia, got an interesting offer from pohltec metalfoam GmbH and went to Cologne to start my new adventure. The main reason for choosing pohltec metalfoam is obvious. Getting the chance to turn the material I studied for more than 6 years into a real application and product is invincible. Foams, Aluminium Foam Sandwiches to be more precise, are not only known for its particularly fascinating cellular structure, but rather for its high stability, its minimum weight, what makes it interesting for bear loading and functional applications in architecture, automotive and various very specific industries. My background in fundamental science, metallurgy and the physics of foams combined with the opportunity to bring metal foams in daily life, encourage and inspire me everyday.

In 2013 I found a Sport what arouses my interest and mesmerize me: RACKETLON

Racketlon is a combination sport where competitors play a sequence of the four most popular racket sports: table tennis, badminton, squash, and tennis. It originated in Finland and Sweden and was modeled on other combination sports like the triathlon and decathlon.

In a regulation game, two individuals (or two pairs in doubles) play each other in four sets, one in each sport. Each set has the same format: the serve switches every two points, and the set finishes when one player has earned 21 points with at least a 2 point margin. The sets are played from smallest racket to largest: first table tennis, then badminton, squash, and finally tennis. The player (or pair) who has won the most points overall wins the match. If the score is tied after all four sets, the tie is broken by one extra tennis point. Other than the scoring, each point follows the respective sport's international rules.
