Research summary

His research focuses on immune and genetic determinants of immune activation and the role they play in HIV acquisition, progression and end-organ dysfunction. The laboratory is using a multidisciplinary approach to the study of pulmonary infections among HIV infected individuals, combining epidemiology, clinical aspects as well as study of the microbiome and the interaction with host immune responses. Additional area of research revolves around early markers of tuberculosis acquisition and determinants of susceptibility. The projects rely on local and international cohorts with growing collaboration and exchange in Medellin, Colombia.

Research focus and interests

  • Innate and adaptive (T and B cell) immune responses to influenza infection and vaccination with emphasis on factors associated with Influenza cross-protection and disease severity
  • HIV disease progression. Study of the immunogenetic determinants and the effect of anti-inflammatory interventions on immune reconstitution
  • Tuberculosis: Host gene expression and cytokine profile used to identify latent TB infection and the transition to active disease
  • Clinical management of infectious diseases, pyogenic liver abscess caused by hypermucoviscous klebsiella; HIV care and management of opportunistic infections. POC detection of HIV status.
