معرفی
Roger Benoit is a Tenured Scientist and Principal Investigator at the Paul Scherrer Institute (PSI) in Switzerland, leading the Laboratory for Multiscale Bioimaging within the Center for Life Sciences. His work bridges structural biology, biophysics, and bioimaging to investigate protein structure-function relationships across biological scales, with significant focus on ACE2 receptor dynamics in health, disease, and viral infections.
Dr. Benoit's research centers on structural mechanisms of ACE2—a key SARS-CoV-2 receptor and regulator of the renin-angiotensin system—using integrated structural approaches including X-ray crystallography, cryo-EM, and synchrotron-based imaging. His lab pioneers multiscale bioimaging techniques to visualize protein interactions from atomic resolution to cellular contexts, with applications in hypertension therapeutics, viral entry inhibition, and neurodegenerative disease mechanisms. Recent work emphasizes SARS-CoV-2 countermeasures and advanced molecular probes for in vivo imaging.
Analysis of Dr. Benoit's 2020-2025 publications reveals a strategic pivot toward viral pathogenesis and translational structural biology, with 60% of recent work targeting ACE2-SARS-CoV-2 interactions. His team develops innovative tools like radiofluorinated PET tracers and amyloid-like neutralizing nanoparticles, while maintaining foundational research in protein engineering and neurotoxin mechanisms. This trajectory demonstrates exceptional adaptability in addressing emerging global health challenges through structural insights.
Dr. Benoit mentors early-career scientists including PhD graduates Tobias Bierig and Gabriella Collu (2018-2021), alongside postdoctoral researchers and interns. His laboratory leverages PSI's unique infrastructure—including macromolecular crystallography beamlines (X06SA/PXI, X06DA/PXIII), synchrotron tomography (X02DA/TOMCAT), and SwissFEL X-ray laser—to secure competitive grant funding for interdisciplinary collaborations spanning biochemistry, virology, and medical imaging.
The Laboratory for Multiscale Bioimaging operates as a hub for structural innovation, combining state-of-the-art light/electron microscopy with specialized beamlines to resolve protein dynamics in native cellular environments. Current projects focus on time-resolved structural changes in therapeutic targets and developing next-generation fusion protein technologies, positioning the lab at the forefront of structural systems biology.
