Research emphasis: Dr. Agca's research interests are in the development of more efficient methods for cryopreservation of mammalian germplasm (i.e gametes, embryos, ovarian tissue) from scientifically and economically valuable (e.g. transgenics, knockouts) animal models for genome resource banking purposes. He is also interested in the development of assisted reproductive technologies in order to utilize such cryopreserved biomaterials more effectively.
