About me

  • I am a postdoctoral researcher at Karolinska Institutet. My main research of
    interest is creating a single-cell atlas of the B cell compartment across
    human tissues using state-of-the-art technologies
    I am a postdoctoral researcher at Karolinska Institutet. I did my PhD in
    Biomedicine at the UPF in Spain. During my PhD I uncovered an unanticipated
    role of the exonuclease Xrn1 in translational control under physiological
    conditions and in cell adaptation and survival under osmotic stress
    conditions. During 2020, I focused my career on the profiling of immune cell
    and antibody responses in a cohort of moderate to severe COVID-19 patients.
    Additionally, I generated monoclonal antibodies isolated from convalescent
    individuals that neutralize SARS-CoV-2 variants of concern as a putative
    therapy to treat COVID-19. Nowadays, my main research of interest is creating
    a single-cell atlas of the B cell compartment and surrounding
    microenvironment across different tissues in deceased healthy individuals
    using state-of-the-art technologies such as single cell RNA sequencing.

    Air pollutants, particularly particulate matter (PM), pose a major health risk by infiltrating the body and accumulating in peripheral organs, including immune organs. Our research detected PM in organs relevant to immune B cell function. However, the link between PM exposure and B cell-mediated immunity is limited to epidemiological observations. The purpose of this project is to study the effects of PM on human B cell responses through evaluation of postmortem lung-associated tissues with signs of PM exposure. Specifically, we will examine whether lifelong exposure to PM correlates with changes in lymphoid tissue integrity and B cell profiles by immunophenotyping and spatial transcriptomics. Additionally, we will study how PM influences B cell responses to antigens in vitro, unraveling potential links to immune-related disorders. Last, we aim to identify B cell activation pathways affected by PM using molecular techniques. This study contributes to Sustainable Development Goal 3 (Good Health and Well-being), by aiming to characterize the polarization of B cells in the pathologic response to PM and by identifying potential drug targets that modulate immune responses in regions affected by air pollution (Target 3.9). By advancing our understanding of environmental immunology and its clinical significance, this project aims to inform public health strategies to mitigate the health risks associated with air pollution.
