Abstract #

This project aimes to automate the photo-documentation of the growth over time of suspended algae specimen cells in 24-well plates, while serving as an introduction lesson to realising electro-mechanical prototypes from scratch. The underlying objective was to explore the development and implementation of tools and devices that address daily work requirements and do not exist, yet. The project included a stepper motor driven system capable, designed to moving a camera system in two dimensions to document growth of set up specimen. Alongside the exploration of several kinds of hardware components, delving into software and application development was part of the knowledge gathering experience. Using a single-board-computer as operation interface, possibilities of setting up a graphical user interface upon a complete functional operating system opened up. This enables operating the device, and independently controlling the micro-controller that instructs the drivers which again operate the motors. The camera is directly attached to and controlled by the single-board-computer. This breaks the interaction between the the single-board-computer and the micro-controller down to “make a move” <-> “make a picture”.

I am driven by curiosity and fascinated by the rapidly advancing world of medical devices. My strong ability to adapt, gather feedback data, and deliver solutions positions me best in non-routine work processes. I am both a biologist and a developer.

From an early age, I was captivated by nature and the sciences. Throughout my studies and career, I've developed core competencies in histology, physiology, and immunology, while also bridging gaps to automation and data processing in interdisciplinary areas involving computer science.

I was born in 1988 in Zwiesel, Germany. My family moved from the Bayrischer Wald region to Rottal, where my parents started a veterinary business. In 2009, I finished school in Pfarrkirchen and moved to Salzburg to pursue a bachelor's program in Biology. I lived and worked in Salzburg until 2017 when I graduated.

In 2018, I moved to Vienna to start a master's program in Bioinformatics. During this period, I secured my first job and prioritized my independence. From 2020 to 2022, I developed a keen interest and gained experience in histopathology.

In 2022, I joined Sakura Finetek as a Product Specialist in Advanced Staining vulgo Immunohistochemistry. I was responsible for customer support, gathering feedback, and delivering solutions through daily root-cause analysis.
