I defended my PhD thesis in october under the direction of Dr. Juan Anguita's at CICbioGUNE, Spain, During my thesis work I have been involved in a European consortium and project (ANTIDotE) to develop anti-tick vaccines to prevent tick-brone diseases in Euorpe (Sprong et al., 2014). In addition, I have also been focused on deciphering how to use the immunosuppressive tick salivary protein, Salp15 (15-kDa Salivary Protein), in an autoimune disease like Graft versus Host Disease (GvHD) affects the cells of the immune system, specifically focused on CD4 T cell responses and anergy (Tomás Cortázar et al. 2017). Also I had the opportunity to investigate the interaction between Salp15 and the CD4

Currently, I am working as a postdoctoral researcher under the supervision of Dr. Siobhán McClean at University College Dublin. I am in charge of the part of a project funded by Wellcome Trust agency to develop a vaccine against Melioidosis caused by the Gram-negative bacteria Burkholderia pseudomallei. Apart from the purification of new antigens identified by a new method (McClean et al. 2016) and the following characterization of their immunogenic level, my work will be also focused on the characterization of the T cell response against these new and other antigens like BpOmpW (McClean et al. 2016).
