Overview

Principal Investigator

Davide Randazzo, Ph.D.

Dr. Davide Randazzo did his postdoctoral training at the University of Siena, Italy, where he characterized a mouse model knockout for the muscle protein obscurin. He moved to the U.S. in 2014, for a position as a visiting fellow at the NIAMS.

Mission

The principal mission of the Light Imaging Section is to give NIAMS scientists access to state-of-the-art equipment and to offer training and assistance in the acquisition and analysis of high quality scientific images by light microscopy. Furthermore, we use light microscopy and other techniques to elucidate poorly understood aspects of skeletal muscle cell biology, i.e. the organization of muscle microtubules and their role in muscle diseases. We also strive to apply new modalities of light microscopy to the quantitative analysis of skeletal muscle pathologies.

Services

The Light Imaging Section is equipped for widefield and confocal microscopy, multi-photon microscopy, TIRF, high-throughput live cell imaging, and slide scanning. See full list of instruments available.

For access to instruments and more information, contact Dr. Randazzo (davide.randazzo@nih.gov) or Ms. Kenea (aster.kenea@nih.gov).
