Collaboration agreement with stem cell researchers at ETH Zurich

PHI announces the signing of a collaboration agreement with the Cell Systems Dynamics Group at ETH Zurich. The group, headed by Professor Timm Schroeder, is a leading authority in stem cell time-lapse imaging and will advise PHI in the development of the next generation of time-lapse cytometers.

“Timm and his group have built what we are commercializing. Unlike most cell biologists, they have the technical knowledge needed to assemble a time-lapse cytometer – a microscope which allow long-term observation and quantification of cells. In the new HoloMonitor M5 we will combine the fluorescence technology that Timm and his group works with with our holographic technology. HoloMonitor M5 will be the first of a new generation of scientific instruments that will revolutionize cell biology.”, says Peter Egelberg, CEO of PHI.

“Timm has earned recognition as a key opinion leader through his work with stem cells and time-lapse imaging. I feel honored to have the opportunity to work with him. The collaboration brings PHI a lot closer to our initial goal, to reach market acceptance and through this establish our products on the market.”, continues Peter.

“Quantifying cellular and molecular behavior at the single cell level and over time is crucial for a full understanding of any cell system. Time-lapse cytometry is the ideal approach to enable these analyses. However, the lack of complete user-friendly off-the-shelf technical solutions currently limits its successful use to few expert laboratories. I am convinced that improved time-lapse cytometry will enable the next level of insight in future academic research, pharmaceutical screening, clinical diagnostics and quality control in cell therapy.“, says professor Timm Schroeder.

PHI has now signed collaboration agreements with three key opinion leaders. The company’s short-term goal is to sign collaboration agreements with four key opinion leaders.


Professor Schroeder has several publications in Nature and Science. He and his group was recently recruited by the Department of Biosystems Science and Engineering (D-BSSE) of ETH Zurich. The D-BSSE is an interdisciplinary life science research environment located in Basel. Basel is a hot spot of life science and the home of both Novartis and Roche.


ETH Zurich regularly appears at the top of international rankings as one of the best universities in the world. Twenty-one Nobel Prize winners have studied, taught or conducted research at ETH Zurich. The most famous of them is Albert Einstein.
