Jonas Schöndube


Engineer | Dr.-Ing.

Jonas holds a B.Sc. in Mechanical Engineering and a M.Sc. in Micro and Nano Systems from ETH Zurich. He performed his Master’s thesis in the field of microfluidics at Stanford University, USA. He is expert in microfluidics, micro-fabrication, bioprocessing and cell analysis. Together with Andre he worked on the single-cell dispensing technology and its market readiness during their PhD studies at the University of Freiburg and at CYTENA. As CEO at CYTENA Jonas is mainly responsible for corporate development and partnerships.

Andre Gross


Engineer | Dr.-Ing.

Andre studied Microsystems Engineering at the technical faculty of the University of Freiburg (IMTEK) where he finished his diploma in 2010 with focus on biotechnology and biomedical engineering. In his PhD thesis he developed core parts of the single-cell dispensing technology. His key competences are in micro-fluidics, optics, software development and single-cell handling. Before co-founding CYTENA, he was group leader of the “cell dispensing” research group at IMTEK. Three years’ experience in project management and assisted writing of several successful granted research proposals (EU FP7, EU H2020, etc.) completes his portfolio. As CTO, Andre Gross is responsible for product development, certifications, production and quality management.

Julian Riba


Engineer | Dr.-Ing.

Julian graduated with a diploma in mechanical engineering from the Technical University of Munich (TUM). During his PhD studies at IMTEK, University of Freiburg, he pioneered single-cell dispensing of bacteria and further developed some of CYTENA´s core technologies. His key competences are single-cell isolation, single-cell molecular biology, and software development. Julian has initiated numerous successful scientific collaborations at CYTENA and has secured several research grants totaling 1.3 Mio. €. He joined CYTENA in 2016 as application specialist. Since 2018 he serves CYTENA as CSO.
