Sjors Hendrik Willem Scheres FRS (born 1975) is a Dutch scientist at the MRC Laboratory of Molecular Biology Cambridge, UK.

[1][2] Scheres studied Chemistry at Utrecht University in The Netherlands, and spent nine months at the European Synchrotron Radiation Facility in France for his undergraduate research thesis.

Scheres worked as a Postdoctoral researcher at the Spanish National Center for Biotechnology (CNB) with José Maria Carazo from 2003-2010, where he developed classification algorithms for Cryogenic electron microscopy (cryo-EM) images based on Maximum likelihood estimation.

[7] Besides developing algorithms for cryo-EM image processing, Scheres has also collaborated with experimental groups to solve important protein structures.

Using cryo-EM image processing methods that were developed by Scheres, they solved the structure of Amyloid fibrils of Tau protein from the brain of an individual with Alzheimer's disease.
