Randall Jiménez Quirós is a postdoctoral fellow at the Smithsonian National Zoo’s Center for Conservation Genomics collaborating with the researchers, Dr. Carly Muletz-Wolz and Dr. Brian Gratwicke, along with other collaborators. He studies the skin defense in Appalachian salamanders against the chytrid pathogens Batrachochytrium dendrobatidis and B. salamandrivorans. Particularly, he investigates how the host skin bacteria and peptides interact and influence the infection of these two pathogens in species that differ in chytrid susceptibility. He also studies the functional importance of host-secreted mucus on pathogen-killing ability to better understand pathogen resistance. Randall is a tropical biologist from Costa Rica with a master’s degree in wildlife conservation and management. He performed his doctoral studies at Ulm University in Germany. Over the past years, he has been working with the skin bacterial communities of endangered amphibians of Costa Rica. His work with amphibians seeks to provide important information that seeks to support amphibian conservation and management actions.

The Yonahlossee salamander is a woodland species from the southern Appalachian Mountains in the United States (Brian Gratwicke)
