  • Research Interests

    He conducts research on the molecular mechanism of spermatid head shaping, a process relevant to male fertility. The ongoing research is focused on the role of non-receptor tyrosine kinases and pyrazolo-pyrimidine-type inhibitors on the development of the acrosome (essential for fertilization), the assembly of the acroplaxome (a cytoskeletal plate that modulates exogenous constriction forces during spermatid head shaping) and the assembly/disassembly of the manchette (a microtubular structure involved in nucleo-cytoplasmic transport).
