Mortezaali Razzaghi's research sits at the interface of structural biology and biophysics. My work uses high-resolution methods — notably cryo-electron microscopy (cryo-EM) and X-ray crystallography — to elucidate macromolecular structures and dynamics, revealing mechanistic insights into biomolecular function. My contributions include characterizing protein-nucleic acid structures and advancing our understanding of structure–function relationships in key biological systems, especially on molecular machines supporting genome stability.
