Solving Preclinical Vaccine Challenges | Expert in Adjuvant Design, Mucosal Immunity, and S. aureus Colonization Models

Profile Summary

I am a Ph.D. immunologist and biochemist with over 15 years of experience in vaccine formulation, mucosal immunity, and host–pathogen interactions. My work focuses on solving preclinical bottlenecks in vaccine development, particularly through the use of cationic nanoparticles and adjuvant systems that enhance antigen stability and immunogenicity. Currently, I work as a postdoctoral researcher at the University of Chicago, studying the immune mechanisms that allow Staphylococcus aureus to persist at mucosal surfaces. My expertise includes animal models of colonization, flow cytometry, cytokine profiling, and the design of immune-targeted interventions. I have published multiple peer-reviewed papers on nanoparticle-based vaccine platforms and the immune modulation of persistent bacterial infections. I also bring extensive experience in clinical immunology diagnostics from Cuba, including CNS infection and autoimmune disease profiling using CSF analysis. Whether you're developing a new adjuvant, optimizing mucosal delivery, or troubleshooting an animal model that doesn't match clinical outcomes, I can help translate immunological complexity into actionable decisions for your R&D pipeline. Let’s work together to make your next vaccine, therapeutic, or diagnostic product safer, faster, and more effective.
