We simplify, speed up and miniaturize pollen analysis to enable large scale pollen quality monitoring and unlock its potential to drive yield improvements in breeding and seed production.

Company Portrait

Amphasys‘ mission is to simplify, speed up and miniaturize complex cell analyses and move them to the point-of-use, which may be outside well-equipped research and analytical laboratories.

Amphasys was founded in 2012 as a spin-off from Axetris AG, a company of the Leister group and focuses its activities in developing and marketing a novel, chip-based single cell analysis technology.

The basic technology has been developed in 2004 in collaboration with the Swiss Federal Institute of Technology Lausanne (EPFL).  In 2013 Amphasys was awarded with the most prestigious Swiss startup price by the W.A. de Vigier Foundation. Amphasys was also supported by the Albert Koechlin Foundation and certified by CTI Invest®. Today, Amphasys is a speedily growing high tech company dedicated to reinventing single cell analysis and applying it to industrial production processes.

Dr. Marcel Ottiger, Chairman

Marcel graduated with a PhD degree in Molecular Biology and Biophysics (1996) in the group of nobel prize winner Prof. Dr. Kurt Wüthrich at the Swiss Federal Institute of Technology Zurich (ETH Zurich). He continued his studies with nuclear magnetic resonance at the National Institutes of Health, USA. Back in Switzerland, he joined COMIT as an IT consultant in 1999 and received his degree as executive MBA at the University of St.Gallen (2004). After the company was acquired by Swisscom IT Services, he was promoted to the executive board in which role he was responsible for a business unit consisting of up to 300 consultants. In addition, he was partner at Mecon Measure & Consult GmbH between 2000 and 2012. Marcel was one of the co-founders of Amphasys and joined the company as Executive Partner in January 2014.


Dr. Marco Di Berardino, Vice President of the Board of Directors

Marco received his PhD in Natural Sciences at the Swiss Federal Institute of Technology Zurich (ETH Zurich) in 1996. After his postdoctoral fellowship at F. Hoffmann-La Roche he worked as project manager and business developer in two start-up companies. During that time he obtained his bachelor degree in business administration at the GSBA Zurich. At Axetris AG, a company of the Leister Group, Marco led the development of the Impedance Flow Cytometer from the feasibility to the prototype and raised the awareness for this technology to the cytometry community through numerous publications and presentations. In 2012 he co-founded Amphasys as a spin-off from Axetris AG.


Thomas Bergen

Thomas got his business and economics degree in 1993 from the University of St.Gallen. He was vice president at Migros Bank. In 1999, Thomas co-founded getAbstract. As CEO, he is running the global business of getAbstract from the Lucerne headquarters. From 2003 until 2011, he served as a member of the board of the Swiss Management Association, which he presided for the last two years. He is also a member of the foundation council of the famous monastery in Einsiedeln, lectured on entrepreneurship at the University of St.Gallen and is one of the co-founders of Amphasys.


Christiane Leister

Christiane Leister studied economics at the Christian-Albrechts-Universität, Kiel, Germany. During the first ten years of her career she worked with well-known German family enterprises and thereby developed deep knowledge in finance and controlling. Between 1989 and 1993 she was responsible for executive and strategic assignments in the Leister family enterprise. In succession, she further developed the single enterprise on the basis of new technologies und business activities to the Leister group including eleven companies in three continents. In 1998, Christiane Leister started with activities in the area of microtechnology for gas sensors and micro optics which was then developed to Axetris AG, a subsidiary of the Leister group. In 2016 she was elected by the Swiss Federal Council to become a member of the ETH board (board of the Swiss Federal Institute of Technology).


Heiner Scherrer

Heiner got his diploma as a mechanical engineer at the Swiss Federal Institute of Technology Zurich (ETH Zurich). After two years as assistant professor at ETH he started his own engineering company. In 1985 he co-founded CTC Analytics where he is still engaged as chairman. Heiner joined the board of Amphasys as investor to contribute his knowledge in the design, production and distribution of scientific instruments.

Scientific Advisors

Prof. Dr. Philippe Renaud

Philippe was appointed as professor at the Swiss Federal Institute of Technology Lausanne (EPFL) (Microsystems Laboratory) in 1997. Philippe is also the scientific director of the EPFL Center of MicroNanoTechnology (CMI). His main research area is related to micronano technologies in biomedical applications (BioMEMS) with emphasis on cell-chips, nanofluidics and bioelectronics. Philippe is committed to valorisation of basic research through his involvement in several high-tech start-up companies.


Dr. Iris Heidmann

Iris is CEO and senior researcher on plant cell biology at Acepo, Enkhuizen (NL). Her research and services focuse on pollen viability analysis, plant regeneration systems from somatic and generative cells, mutagenesis and epigenetics. She completed her PhD studies at Wageningen University. Before Acepo, she worked for many years at Enza Zaden and at various research institutes in Germany (Inst. for Horticultural Plant Breeding, Ahrensburg; University of Konstanz, Max-Planck Institute of Plant Breeding Research Cologne). Iris’ knowledge about pollen development and her initial exploitation of Amphasys’ impedance flow cytometer for pollen analysis was essential for all further developments in this field.


Dr. Ladislav Kucera

Ladislav received his PhD in electrical engineering from the Swiss Federal Institute of Technology Zurich (ETH Zurich) in 1997. After working as Director Electronics & Control at ESEC AG, where he was leading more than 50 engineers, he founded his own company, Triamec Motion AG. He is an expert in HF Signal Processing, has a profound theoretical background of impedance analysis and a compelling experience in the programming of embedded systems. Ladislav was instrumental in developing Amphasys’ electronics hardware for the impedance flow cytometer.
