Maria del Pilar Martinez Viedma, PhD

Staff Scientist



I am a staff scientist with a strong background in Microbiology, Molecular Biology, Virology and Immunology. I have experience working in diverse settings where I applied my knowledge and acquired cutting edge techniques that are reflected in my strong publication record.

I gained great part of my technical skills and knowledge in Microbiology and Bacteriology during my Ph.D. training at the University of Jaen (Spain) where Dr. Antonio Gálvez mentored me. My thesis was focused on food safety with the study of bacteriocines as a natural preservative against food pathogens such as B. cereus, S. aureus, L. monocytogenes among other pathogenic bacteria. My undergraduate studies were funded by a Fellowship from the University of Jaen in Spain. I also obtained the European Doctorate Mention as a result of an exchange stay in the laboratory of Dr. Danilo Ercolini (University of Naples Federico II, Italy).

As a Postdoctoral Fellow in the Infectious Diseases Department at the Boston Children’s Hospital, Harvard Medical School, I continued expanding my knowledge in Molecular Biology, Virology and Immunology. I investigated the molecular mechanisms by which SIV (Simian Immunodeficiency Virus) cause AIDS in non-naturally infected non-human primates, and I compared the outcome of this infection to naturally SIV-infected non-human primates, where SIV infection does not lead to AIDS. Particularly, I studied gene expression and cellular pathways activated in macrophages from these two different models.

Throughout my experience and training, I have gained a unique perspective in approaching a broad range of projects, people and environments.

Research Priorities

  • To identify immunodominant epitopes for multiple Flavivirus species.
  • To design, develop, and implement a seroimmune diagnostic method for ZIKV detection, based on the detection of specific epitopes from the virus.
  • To determine ZIKV seroprevalence in serum samples collected from outbreak regions.
