Olivier Pertz, Professor
Olivier received a PhD in Biophysical Chemistry from the Biocenter of the University Basel. He then performed his Postdoc at the Scripps Research Institute in La Jolla, CA, where he developed new technologies to image signaling dynamics in single living cells. Before joining the Institute of Cell Biology at the University of Bern, he was a Swiss National Science Foundation Professor at the Department of Biomedicine of the University of Basel. In the lab, he tries to convince people to produce ever more images of cellular signaling, and to setup new computational approaches to make sense of these complex datasets. In his free time, as a good swiss person, he has interests as diverse as climbing, bouldering, mountaineering, and ski-mountaineering, as well as educating two teenagers.
Paolo Armando Gagliardi, Postdoc
Raised between vineyards in south-Piedmont in Italy, Paolo studied biology in Torino where he later received a PhD in molecular medicine. During his Master, PhD and first postdoc, Paolo worked in the Candiolo Cancer Institute, a research hospital close to Torino in Italy. His expertise ranges from cell biology and biochemistry to advanced and super resolution microscopy. Among his major achievements, Paolo discovered a new signalling pathway that connects the kinase PDK1 to myosin contraction through the activation of MRCKα. By studying the latter protein, he found that its cleavage by caspases is an important event in the control of actomyosin cytoskeleton during apoptosis and epithelial extrusion. Paolo joined the Pertz lab in 2017, aimed at deciphering the mechanisms of collective signalling dynamics events in epithelia and the effects of oncogenic mutations on such behaviour. Here, he found the right environment, technologies and expertise to carry on his project. Paolo has perfectly integrated in the Swiss atmosphere and in his free time he enjoys trail running, hiking and snowboarding.

Lucien Hinderling, PHD student
During my BSc thesis in computer science at the University of Fribourg, I worked on 3D terrain reconstruction and georeferencing of hyperspectral UAV images for the University of Göttingen. This project sparked my interest in applying computer vision and machine learning tools for solving biological research questions. From now on on a steady trajectory towards biology, I concluded my MSc degree in Bioinformatics and Computational Biology with a thesis in this lab, building a computer vision pipeline for segmenting and tracking MCF10A epithelial cells in real time. I’m now interfacing this pipeline for my PhD as part of an experimental platform, that allows real time control of cell signaling states at single-cell level using optogenetics. This will allow us to invoke synthetic behavior in selected cells of a tissue. Studying the response of surrounding cells to the stimulated cells, enables us to better understand emergent properties of cell ecosystems. By manipulating signaling pathways that are regulators of cell fate decisions, such as the MAP kinease ERK, we will be able to invoke cell fates such as proliferation, motility or death in specified cells, allowing us to grow cell tissues in arbitrary shapes.
