Dr Zoran Marinović is primarily a cell biologist and focuses on implementing cell biology techniques in reproductive biology and toxicology. In reproductive biology, he is developing models for in vitro gametogenesis and transgenesis, thus developing novel approaches in fish conservation and biotechnology. Key aspects in this research are the in vitro culture and transplantation of spermatogonial stem cells in fish. He is also developing in vitro models and tools for toxicological studies which will contribute to the implementation of the 3R strategy in animal research.
