CEO, geschäftsführer, Jörn Rickert, CorTec

Dr. Jörn Rickert

Chief Executive Officer

Jörn Rickert studied biology in Hamburg and Freiburg. His dissertation on the representation of movement in the motor cortex made an important contribution to basic neurobiological research. When writing his dissertation, he also had the idea to use scientific research as a bridge for implementation and to start a business focusing thereon.

After completing his PhD in 2004, he became project manager at the Brain Machine Interfacing Initiative (BMII) in Freiburg, undertaking the task of transferring the research results of this group of scientists into a marketable product. Since the foundation of CorTec in September 2010 he has been the company’s CEO.

Bernhard Meder

Bernhard Meder started to work in the field of radio and television technology. In the year of 1980 he founded MEDER CommTech (formerly MEDER Funk) in Singen (Hohentwiel). In 2012 he passed the management to his son Tobias Meder, but still he follows and supports the development of the company.

He started a second enterprise in 1986 when he founded MEDER electronic Group which soon started to act globally with subsidiaries in Europe, Asia and the USA. After more than 25 successful years in the field of reed technology he finally sold the company to the US-based Standex International Corp.

Since that time he concentrates on investments with a focus of the sectors of telecommunications, medical engineering and renewable energies. Apart from the financial aspect Bernhard Meder emphasizes to support the mostly young companies with his knowhow from 35 years of experience in all areas of corporate management.

Scientific Technical Advisory Board


Prof. Dr. Volker A. Coenen

Volker A. Coenen is medical director of the Department of Stereotactic and Functional Neurosurgery at the Department of Neurosurgery at the University Medical Center Freiburg.

Before he was working at Uniklinik RWTH Aachen as head of the the Division for Functional Neurosurgery. After a fellowship in the field of functional and stereotactic neurosurgery at the University of British Columbia in Vancouver, Canada, in the years of 2007 and 2008 he acquired a professorship of stereotaxis and MR-based operative techniques at the University Hospital of Bonn. Since 2013 he is Full Professor (W3) of Stereotactic and Functional Neurosurgery in Freiburg apart from his position as medical director.

In his research Professor Coenen is concerned with the subject of neuroprosthetics since 2001 specializing on deep brain stimulation (DBS). Focus areas are Parkinson’s disease, tremor and dystonia. In addition he is also working in the field of treating therapy-resistant epilepsy with stereo-EEG, Vagus Nerve stimulation or DBS.

His research priorities include the development of biocompatible construction and interconnection technologies as well as the use of microsystems for neuroprostheses and neuromodulation.


Prof. Dr. Ulf Ziemann 

Ulf Ziemann studied medicine in Göttingen. Since 1996, he has been a neurology specialist. He completed his habilitation in neurology and clinical neurophysiology at the University of Göttingen in 1999. From 2004-2012, he was chief physician of the Clinic for Neurology at the University Hospital Frankfurt. In May 2013, he became medical director of the Department of Neurology with a focus on vascular neurology at the University Medical Center Tübingen.

His scientific work focuses on exploring the plasticity of the brain, its capacity to learn and to reorganize – particularly in cases of physical and cognitive impairments. His research has a particular focus on impairments caused by strokes or multiple sclerosis.

At the University Hospital Frankfurt, Prof. Ziemann was director of a motor cortex research group. He was also coordinator and spokesperson of the interdisciplinary collaborative research “Neuronal Coordination Research Focus Frankfurt” (NeFF). In Tübingen, he will continue to dedicate himself to the systems-neurophysiological exploration of the plasticity and reorganization of the brain.
