Alberto Bartesaghi, Ph.D.
Dr. Bartesaghi has pioneered the development and application of novel image processing methods in three-dimensional (3D) electron microscopy to determine the structures of a variety of macromolecular assemblies of fundamental biomedical interest. He is responsible for the design, automation and optimization of image processing workflows, both for single-particle cryo-electron microscopy (cryo-EM) and cryo-electron tomography (cryo-ET) modalities, and for managing the computational resources of the group. This state-of-the-art processing infrastructure serves as a powerful tool to elucidate protein structure at the highest possible resolution of biomedically relevant complexes, including membrane proteins, transporters involved in signaling and metabolism, and glycoproteins of enveloped viruses.

Dr. Bartesaghi's research is devoted to the development of computational imaging technologies that are the frontier of the cryo-electron microscopy (cryo-EM) field. He develops advanced computational techniques that serve as powerful tools for structure determination of a variety of macromolecular complexes, to efficiently and accurately convert raw images into three-dimensional (3D) representations of assemblies at the highest possible resolution. Importantly, these methods address essential technical aspects that are necessary for the extension of methods in cryo-electron microscopy to study small dynamic protein complexes, including membrane proteins such as G-protein-coupled receptors, transporters and channels that are of fundamental biomedical interest.
