I’m an experienced scientist and engineer with a strong background in optical metrology, data analysis and imaging for manufacturing processes.
I’m a passionate collaborator, empathetic supervisor with leadership experience and an engaged reviewer.
Currently, I’m a Walter-Benjamin-Fellow
A prestigous fellowship for conducting post-doctoral research in international contexts funded by the German Research Foundation DFG. For more information, please refer to their website. and a Visting Professor at RMIT University in Melbourne, Australia.
My work is essentially translating knowledge into application!
The core of my research is centered around precise metrology approaches in manufacturing. More precisley, my reaserch aims always to develop sensing or monitoring solutions that will work while a manufacturing process is running. My work is concerned with designing optical measurement systems, implementing data acquisition schemes as well as data analysis routines which serve the highes requirements of speed, precision and repeatblity. I have developed systems for roughness, dimensional and geometrical measurements as well as the detection of anomalies and errors.
Current Focus
The main focus of my curent work is development of computational strategies to improve the measurement range and precission of two approaches in surface characterization for metal-based additive manufacturing (AM).
My work will go beyond the state of the art by enhancing the two optical approaches, Dispersion encoded low-coherence interferometry (DE-LCI) and Dark-field scattering metrology (DfS) with multi-spectral, multi-angular and ghost imaging capabilities in order to improve their performance in dynamic range, measurement speed, material agnostic behaviour and precision. Furthermore, I will develop advanced algorithms for compressive sampling (CS), sensor fusion (SF) as well as noise reduction and regression, based on hybrid approaches -a combination of deterministic and ML-approaches- in order to increase speed and the information content. These aspects will enable the combination of DE-LCI and DfS to form a robust, industry-ready shape and surface monitoring system for AM. It is anticipated that this kind of AM-tailored sensors will result in a new level of in-line integration, autonomous operation as well as closed-loop control. Closed-loop control closes the gap for large-scale industrial usage of AM, increases the quality of its builds and reduces costs of investment as well as ownership.
This work is mainly happening within the frame of a Walter-Benjamin-Fellowship which is funded by the German Research Foundation DFG. I have to pleasure to work and research within the Centre for Additive Manufacturing of RMIT University.
Experience and Achievements
I have a long experience in developing new knwoledge and applied research in science and industry. I have successfully developed very high-dynamic range metrology, applicable in the semiconductor industry, during my PhD research with Westsächsische Hochschule Zwickau and Technische Universität Dresden both in Germany. In context of applied research, I have worked as a group leader for Fraunhofer IWSSpecifically, I helped to establish the Center for Optical Metrology and Surface Technology in Zwickau which was founded as a joint venture between Fraunhofer IWS and Westsächsische Hochschule Zwickau in 2015.. Within this position, I have developed skills in leadership, project acqusition, conceptiolisation and managment as well as in communication both to industrial partners as well as to the general public. In this role, I have acquired projects with regional, national as well as international partners in consortias ranging from 2 to 20 parties. Technological, strategic as well as administrative leadership for teams of up to 10 persons was my daily job before specialising in scientific research and teaching in my current position.
I have published works as books and book chapters for Springer Nature, as research articles in well-regarded journals like Optics Express and Sensors as well as in conference proceedings for SPIE and OPTICA.

Community Engagement and Review
Alongside my research and teaching activities, I’m very engaged in the scientific community, specifically as a member of SPIE and the OPTICA societies. Both of which I attend various conferences and engage in chairing or publication activities. I’m a regular reviewer for various journals such as Applied Optics, Sensors and Applied Sciences. I’m also on the board of reviewers for Advanced Optical Technologies as well as for Metrology. Most recently, I have been the co-editor for a Special Issue in Next-Level Surface Metrology as well for a Focus Issue on Metrology in Advanced Manufacturing.
I love to communicate my research and scientific topics which leads me rarely to write short articles or participate in programs for pupils and young scientist.
Musical Outreach
One of my more unsual communication efforts is called harte echtzeit. Using this moniker, I perform live coded electronic music from scientific data such as gravitational waves. Feel free to listen to a few of my tracks here on bandcamp.
