Research Interests:

Dr. Ludtke's work focuses on electron cryomicroscopy and scientific image processing. While much of his group's focus is on computational work, as codirector of the National Center for Macromolecular Imaging, Dr. Ludtke also has access to all of the NCMI facilities, and his lab does experimental work as well. His interests cover a wide range of techniques in this field, but single particle reconstruction is my primary focus, and my major contribution to the field is the development of EMAN, a software suite for processing images of individual molecules and producing 3D structures at subnanometer resolution. This is extremely computationally intensive work, and his lav have several large in-house Linux clusters used in processing and development. His other interests include development of ontology-based scientific databases and scientific visualization and animation. He is involved in a wide range of collaborative biological projects including chaperonins, protein-lipid interactions, ribosomes, ion channels, and many others.
