I obtained my PhD degree in Biology from the University of Porto in 2013. In 2015, I joined the laboratory of Professor Sabine Ehrt at Weill Cornell Medicine (New York, US) as a postdoctoral associate to work in Mycobacterium tuberculosis target biology. From 2020 until 2023, I held junior faculty positions at Weill Cornell Medicine (New York, US), first as Instructor and later as Assistant Professor of Research.
As junior faculty, I have established an independent line of research, supported by a NIH/NIAID R21 award (Principal Investigator), aiming at the subversion of M. tuberculosis adaptations to the host to eradicate infections.
In July 2023, I joined the Immune Regulation research group at i3S as a CEEC Assistant Researcher to establish a team under the umbrella concept of pathogens target biology, with a current focus on M. tuberculosis. Using pathogen genetic screens (transposon sequencing and CRISPR interference) or clinical isolates libraries as starting points of inquiry, we aim at:
- Identifying and understanding the biological function of novel drug targets.
- Unveiling drug mechanisms of action, tolerance and resistance.
