Dr. Theerawat Tharasanit is an Associate Professor and Director of the Center of Excellence for Veterinary Clinical Stem Cell and Bioengineering, Faculty of Veterinary Science, Chulalongkorn University, Thailand. His research focuses on reproductive biotechnology, especially the development and optimization of assisted reproductive technologies (ARTs) in domestic and wild animals. He specializes in oocyte and embryo cryopreservation, ICSI, IVF, and embryo transfer, with particular success in enhancing feline oocyte cryotolerance using membrane-permeable cryoprotectants such as trehalose. He is also a pioneer in spermatogonial stem cell (SSC) isolation and culture, advancing fertility preservation techniques for valuable and endangered animals. His interests extend to gene editing and transgenesis to explore reproductive gene function, and the use of induced pluripotent stem cells (iPSCs) for veterinary regenerative applications. Dr. Tharasanit bridges basic science with clinical application to support fertility preservation, genetic conservation, and animal breeding. His research has been widely published in international journals and contributes significantly to reproductive science and conservation.
