Founders

abberior our passion

The founders of abberior are pioneers that have been shaping the field of fluorescence microscopy since the mid-1990s. Today, they are active at abberior, where they continue to contribute their extensive know-how in all aspects of the company.

Prof. Dr. Dr. Stefan W. Hell

Stefan W. Hell is a director at the Max Planck Institute for Biophysical Chemistry in Göttingen and the Max Planck Institute for Medical Research in Heidelberg, Germany. Having discovered his love of science at school, he decided to study physics at the University of Heidelberg where he received his doctorate in 1990. At around that time, Stefan realized that state transitions of fluorophores can be harnessed to radically overcome the diffraction resolution barrier in a light-focusing fluorescence microscope. This was at a time when the world thought that sharper images would be possible only by confining light with a nanosized mechanical tip, or that it was simply impossible. Thus, he became the first scientist to conceive, validate and apply a viable concept for overcoming Abbe’s resolution barrier. His discovery laid the foundation of modern “superresolution” fluorescence microscopy and led to the development of optical “nanoscopes” which allow the visualization of molecular details in cells at nanometer length scales. For his pioneering role, Hell has received many awards including the Kavli Prize in Nanoscience and the Nobel Prize in Chemistry in 2014. Since then, he has kept pushing the performance of superresolution fluorescence microscopy towards realizing his longstanding dream of a lens-based microscopy with molecule-size spatial resolution. Together with Gerald Donnert, Stefan Hell initiated the founding of the abberior group. He also serves as its main scientific advisor.

Dr. Gerald Donnert

Dr. Gerald Donnert is the managing director of both, Abberior GmbH and Abberior Instruments GmbH. He graduated with a thesis on spectroscopic aspects of fluorescent labels used in STED microscopy in the Department of NanoBiophotonics, Max Planck Institute for Biophysical Chemistry in Göttingen, Germany. He (co-) authored several scientific papers during that time. After more than three years of management consulting experience with McKinsey&Company in international, mainly strategically focused projects in the global high-tech industry, he returned to Göttingen. He is one of the founders of the company.

Dr. Lars Kastrup

Dr. Lars Kastrup is a physical chemist who worked in the Department of NanoBiophotonics at the Max Planck Institute for Biophysical Chemistry for almost 15 years. During his scientific career, he has acquired a profound knowledge in superresolution microscopy and STED microscopy in particular. He (co-)authored several scientific papers. At Abberior Instruments, he also contributes his extensive experience in scientific presentation and project management. He is one of the founders of the company.
