معرفی
Roger Sauser is a Lecturer at the École Polytechnique Fédérale de Lausanne (EPFL), holding dual appointments in the College of Management of Technology (CMS) and the School of Basic Sciences (SB). Within CMS, he delivers foundational mathematics and physics instruction for the preparatory year program, covering Newtonian mechanics and numerical methods in Python. Concurrently in SB's Institute of Physics (SPH), he teaches physics courses to management and architecture students, emphasizing real-world modeling applications and vector calculus.
His research expertise centers on cardiovascular biophysics, with focus areas including calcium signaling in vascular smooth muscle, mechanical properties of migrating cells, and mathematical modeling of vasomotion. Key interests span vascular dynamics, intercellular communication mechanisms, and the emergent properties of electrically coupled cellular networks. His work integrates experimental physiology with computational approaches to unravel how mechanical stresses and endothelial interactions regulate blood vessel function.
Analysis of his 2004-2010 publication record reveals a cohesive research trajectory in arterial biophysics. He pioneered investigations into calcium wave propagation in arterial strips, force transmission mechanisms in cellular migration, and the role of gap junctions in vascular coordination. His studies consistently employ mathematical modeling to explore arterial wall stress effects, synchronization phenomena in smooth muscle populations, and endothelial-smooth muscle signaling pathways, contributing to fundamental understanding of blood flow regulation.
No documented scientific awards or major research grants were identified. Similarly, there is no public information regarding doctoral student supervision or leadership of dedicated research laboratories.
His collaborative research was conducted within Jean-Jacques Meister's biophysics group at EPFL, working closely with co-authors including M. Koenigsberger, D. Seppey, and M. Lamboley. While not leading an independent laboratory, his contributions form part of broader interdisciplinary efforts to model biological systems at cellular and tissue levels, with particular emphasis on vascular physiology and mechanobiology.
