The 4th ISTT Young Investigator Award goes to Pablo Ross

Pablo Ross 9-22-15

The International Society for Transgenic Technologies (ISTT) is pleased to announce the awardee for the 4th ISTT Young Investigator Award, generously sponsored by ingenious targeting laboratory (iTL). ISTT created the Young Investigator Award, with one goal: identify and recognize young scientists who will keep the field of transgenic technologies vibrant with new ideas and innovative research. After careful evaluation of the nominated candidates, the Award Evaluation Committee unanimously selected Dr. Pablo Ross (Department of Animal Sciences, University of California, Davis, CA, USA).

Pablo is perfectly fitting with the criteria required for this price. Veterinarian by training, gaining his initial degrees in Argentina, he has obtained his PhD in 2007 from the Michigan State University in the Laboratory of Cellular Reprogramming. In 2009 he joined the Department of Animal Science of the University of California Davis where he is running his own group and has obtained this year an Associate Professor position.

Pablo presents as a young, energetic and very talented individual. We are convinced that his research will considerably impact the field of large animal transgenesis. His specific niche is that of livestock embryo technologies and stem cells in which he is working by combining studies in a wide range of livestock species – cattle, sheep, horses and pigs. Among his key findings is the derivation and more importantly maintenance of iPS/ES-like cells in livestock species, a domain where the mouse methods are not always applicable. In parallel he is active in producing and characterizing novel gene edited and transgenic livestocks using for instance the CRISPR/Cas9 technology, and has more recently developed new approaches for interspecies blastocyst complementation, combining primate stem cells and livestock host embryos.

Dr. Pablo Ross will attend the next 13th Transgenic Technology (TT2016) meeting in Prague (Czech Republik, 20-23 March 2016) where he will receive the corresponding diploma and will deliver a talk summarizing his scientific achievements and giving us a unique opportunity to hear and learn more about the major recents achievements of the pioneers and current key players in the field.

For the first time the ISTT will be awarding the Young Investigator Award to a scientist belonging to the group of molecular biologists and geneticists working with livestock animals and dealing and investigating with non-rodent species. In fact, they concentrate their work on species which have an obvious and increasing potential impact in our Society, namely species that we eat, that better match our human physiology and can be used as models that can be better utilized for the understanding and treatment of human diseases.

The following articles represent some of his recent findings published in the last years, highlighting his most recent contributions to the field. These publications have had a tremendous impact in the animal transgenesis field.
