Summary

Davide Randazzo, Ph.D., received his B.S. in biological sciences (summa cum laude) in 2005 at the University of Palermo (Italy) discussing a thesis focused on the regulation of muscle-specific transcription factors during early and late muscle cell differentiation. This work continued as Dr. Randazzo earned his doctoral degree as part of a partnership with the University of Palermo and the National Council of Researches, Italy, from 2007 to 2009. In 2010, he moved to the University of Siena for a postdoctoral position where he characterized a mouse model knockout for the muscle protein Obscurin. In 2014, he moved to U.S. for a position as a visiting fellow at the NIAMS.

Research Statement

Dr. Randazzo's research focuses on: skeletal muscle physiology; structural organization of the sarcomere in striated muscles; organization and function of the microtubule cytoskeleton in healthy and diseased skeletal muscle fibers; and Duchenne muscular dystrophy and related murine models.
