Sarah Butcher

Sarah Butcher is a Professor of Microbiology at the University of Helsinki, affiliated with the Faculty of Biological and Environmental Sciences and the Molecular and Integrative Biosciences Research Programme. She serves as a supervisor for doctoral programmes in Integrative Life Science and Microbiology and Biotechnology. Her research focuses on structural virology, particularly using electron microscopy to study virus structure, assembly, and host interactions. She leads the Cryo-Electron Microscopy Facility and coordinates the FINStruct Structural Biology Finland infrastructure.

Her research interests span structural virology with emphasis on picornaviruses, coronaviruses, and flaviviruses. She applies advanced techniques including cryo-electron microscopy, X-ray crystallography, and image processing to understand viral architecture, host-pathogen interactions, and mechanisms of viral entry and assembly. Her work has significant implications for antiviral drug development and vaccine design.

Her recent publications reveal a strong focus on viral structure-function relationships, particularly in tick-borne encephalitis virus, coxsackieviruses, and SARS-CoV-2. Her research bridges structural biology with virology, producing insights into viral maturation, membrane interactions, and antiviral strategies. She has been instrumental in developing community standards for cryo-EM data validation and archiving.

• Alfred Kordelin Prize (2017)
• Maikki Friberg award (2013)

Professor Butcher has supervised numerous doctoral and master's students and serves on multiple doctoral thesis committees. Her research has been supported by major competitive funding including Academy of Finland grants, Biocenter Finland, Sigrid Juselius Foundation, and European Commission projects. She currently leads the FINStruct infrastructure and the Instruct-ERIC Centre Finland.

She directs the Cryo-Electron Microscopy Facility at the Institute of Biotechnology and coordinates the FINStruct Structural Biology Finland infrastructure, which provides state-of-the-art structural biology resources to researchers across Finland. Her team specializes in advanced cryo-EM techniques for studying complex biological structures, particularly viral particles and membrane proteins.
