    Benedikt Geier

    Postdoctoral Scholar, Infectious Diseases

    BioB.Sc. Biology, Ludwig Maximilian University (LMU), Munich/Germany (2013)
    M.Sc. Biology and bioimaging, Ludwig Maximilian University (LMU), Munich/Germany (2015)
    Ph.D., Animal-Microbe Symbioses, Max Planck Institute for Marine Microbiology in Bremen/Germany (2020)

    Benedikt joined the Amieva Lab from Germany in 2022. During his B.Sc. and M.Sc. programs in zoology, he became fascinated with 3D imaging approaches to study small animal microanatomy. He spent his PhD developing in situ imaging approaches to study deep-sea symbioses and fell in love with studying host-microbe interactions. In the Amieva Lab, Benedikt will advance his previously developed correlative chemical imaging techniques to resolve metabolic and cellular interactions that drive H. pylori pathogenesis in the gastric glands.

  • Izabela Mauricio Rezende

    Izabela Mauricio Rezende

    Postdoctoral Scholar, Infectious Diseases

    BioI have a B.S. in Biology, M.Sc. in Immunology and Infectious diseases, Ph.D. in Microbiology, and a broad background in virology/microbiology and molecular biology applied to viral infectious diseases. I have a vast knowledge of classical virology, molecular biology, phylogenetic analysis, serological, and molecular diagnosis. I am working on recent YF outbreaks, focusing on viral dynamics, ecology, diagnosis, and the investigation of virological, immunological, and clinical aspects during the course of infection. We have supported the hospital and Secretary of Health of Minas Gerais with some laboratory testing applied to diagnosis of YF, viral genotyping related to YF patients suspected to have adverse events following vaccination, and other analysis. We also have been working on dynamics of the outbreak, on the virological, epidemiological, and immunological aspects during the course of yellow fever. During the COVID-19 pandemic, we also supported the Brazilian Ministry of Health with the SARS-CoV-2 diagnosis in human samples and also in the investigation of the SARS-CoV-2 RNA in surfaces of density public areas of Belo Horizonte. Since Nov/2018 I had been an editor in the journal DocĂȘncia do Ensino Superior (RDES / GIZ / UFMG) and in Jan/2020 I became Editor-in-Chief.

  • Praveesh Valissery

    Praveesh Valissery

    Postdoctoral Scholar, Infectious Diseases

    BioPraveesh completed his Ph.D. at Jawaharlal Nehru University (New Delhi, India). He has experience in organic chemical synthesis and molecular biology. Under the supervision of Prof. Suman Kumar Dhar, he studied the cell cycle of the malaria parasite (Plasmodium falciparum) and worked on the optimization of water-soluble Artemisinin nanopreparations in the mouse model of malaria (Plasmodium berghei). He also helped in the synthesis and characterization of a novel class of hybrid antimalarial drug, CQ-CFX. In the Egan lab, Praveesh is interested in exploring essential host-parasite interactions taking place at the surface of the red blood cell during invasion. In the long term, he hopes to acquire enough skill to study and develop antimalarial vaccine antigens and improve existing vaccine formulations.
