About me

I am a physicist with many years of experience in the analysis and optimization of high-power laser systems. After working in industrial laser R&D for more than 10 years, I am now focusing on data science and deep learning.

I am passionate about finding solutions to complex problems. My broad technical knowledge allows me to generate added value from even small datasets. 

The data that are already available in a company are often sufficient to sustainably improve the quality of products and processes; if this is not the case, I also can make recommendations on the additional data that should be collected to solve a particular problem.

What makes me unique is that I have experience in both data science and practical industrial applications. This means that the data collected in companies are not just abstract numbers to me— I understand what they mean in practice, in the context of technology and engineering. This allows me to quickly familiarize myself with new topics and efficiently create working models. I focus on creating models that can be fully integrated into technological processes.

Milestones in my career:

Scientific experience:

I studied physics and received a PhD from Leibniz University Hannover. While working toward my PhD, I performed experimental and theoretical work on high-power single-frequency optical fiber amplifiers at a wavelength of 1.5 µm.

Industrial Experience:

In my position as a senior R&D scientist at TRUMPF, a machine tool company, I conducted research on high-power laser components, including physical simulations on thermomechanics and fluid dynamics. To do this, I used the finite element method with COMSOL Multiphysics software. I was responsible for the development of central components from the initial conception, through patent applications, to the volume production. This work was a key contribution to the creation of the TruDisk product line that generated eight-figure euro sales for the TRUMPF company.

I was also responsible for a wide range of tasks, including:

  • Monitoring and analyzing production data (using Python)

  • Supporting the department of quality assurance with specifications and technical advice based on optical metrology (particularly microscopy and interferometry) according to DIN ISO 10110

  • Creating and revising specifications and cooperating with suppliers to improve supply chains and strategic sourcing

My paper entitled “Er-doped photonic crystal fiber amplifier with 70 W of output power” was awarded the annual prize for the best publication at Laser Zentrum Hannover (2011).

I passed my PhD thesis defense with distinction (2011).
