These large-scale flows are generated by the inte­grated activity of thousands of microscopic beatin g filaments attached to cell surfaces (cilia). In cells\, collections of c ilia exhibit highly coordinated temporal patterns known as metachronal wav es. While patterns of cilia temporal coordination have been observed for d ecades\, the mechanisms underlying their formation and their contribution to flow generation remain unclear. The lack of measurements of the geometr ic and dynamic properties of cilia arrays has limited our ability to under stand the mechanisms of pattern formation. In my talk I will discuss the a dvantages of ciliated swimmers as experimental model systems where such me asurements can be readily performed. Performing precise measurements and p erturbations of temporal patterning in cilia arrays will enable the identi fication of the physical mechanisms underlying the emergence of collective behavior. Beyond their biological significance\, arrays of cilia provide an accessible experimental platform to explore the physics of multi-scale pattern formation.\n\n\nBio:\nGuillermina Ramirez-San-Juan earned her PhD in Biophysics under the supervision of Margaret Gardel at the University o f Chicago. Her work in the Gardel lab focused on understanding how cell mi gration is guided by the geometry of the extra-cellular environment. Addit ionally\, during her doctoral studies she collaborated closely with the Ho rne-Badovinac lab to investigate the role of cytoskeletal patterning in or gan morphogenesis.\nThe experience of collaborating across different field s inspired her to become a joint postdoctoral researcher with Wallace Mars hall at the University of California\, San Francisco and Manu Prakash at S tanford University. There she became interested in combining tools from ce ll biology and fluid mechanics to study flow generation by ciliary arrays. \nSince 2023 she is Tenure-Track Assistant Professor at EPFL in the Insti tute of Physics (School of Basic Sciences)\, where she is heading the Livi ng Patterns Laboratory.\nGuillermina Ramirez-San-Juan has always been fasc inated by the diversity of patterns observed in biological systems\, wheth er they exist at the subcellular\, cellular\, tissue or organism scales.\n When not in the lab she is in the kitchen experimenting with new protocols a.k.a. recipes or running by the nearest lake.\n\n\nZoom link (with one-t ime registration for the whole series) for attending remotely: https://go. epfl.ch/EPFLBioETalks\n\n\nInstructions for 1st-year Ph.D. students who ar e under EDBB’s mandatory seminar attendance rule:\nIN CASE you cannot at tend in-person in the room\, please make sure to\n\n send D. Reinhard a no te well ahead of time (ideally before seminar day)\, informing that you pl an to attend the talk online\, and\, during seminar:\n be signed in on Zoo m with a recognizable user name (not any alias making it difficult or impo ssible to identify you).\n\nStudents attending the seminar in-person shoul d collect a confirmation signature after the talk - please print your own signature sheet beforehand (71 kB pdf available for download here).
