Pierre Comizzoli started his career more than 25 years ago as a research veterinarian South America and Africa. He then completed a PhD in 2000 on in vitro fertilization in bovine and deer species. In 2002, he joined the Smithsonian Conservation Biology Institute in Washington, DC to develop new cryo-banking projects on gametes and gonadal tissues from rare and endangered species. This also includes the coordination of reproductive monitoring and artificial inseminations in different species (including giant pandas, clouded leopards, or Eld’s deer). He is leading since 2007 a Smithsonian-wide initiative to improve the management and use of frozen biomaterial collections within the Institution.
