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.

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.

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.
