News
- I have secured a grant to become a Visitor of the Kavli Institute of Cosmology (Cambridge, UK) and fund visits and collaborations for my research group from October 2023,
- I will be joining Newcastle University in Summer 2023 as a Newcastle Academic Track (NUAcT) Fellow.
Career
- since 2018: MPA Postdoctoral Fellow (MPA, Garching),
- 2015—2018: Nova Postdoctoral Fellow (Leiden Observatory, Netherlands),
- 2015: Ph. D. (Institute of Astronomy, University of Cambridge, UK)
Research interests
- Galaxy evolution and the impact of active galactic nuclei (AGN),
- Physics of AGN feedback (e.g. accretion disc winds, momentum-, energy-driving, radiation pressure),
- Outflow driving mechanisms and multi-phase structure in galactic outflows and the circumgalactic medium,
- High-z quasars, supermassive black hole growth, quasar cosmic environments,
- Numerical implementations of AGN Feedback and black hole accretion into (radiation-)hydrodynamic galaxy formation codes (AREPO, GADGET, RAMSES)
Code development
- Documentation for BOLA (Boundary Layer for AGN) can be found here.
Upcoming Talks
- December 2023: Review on `the modelling of AGN accretion and feedback in galaxy formation simulations' @Black Holes on Broadway (Flatiron Institute, New York, USA)

Research Highlights
Public Engagement
I frequently speak on topics ranging from the solar system to relativistic cosmology to primary and high-school audiences. Example talks include:
- "O Sistema Solar e o Universo/ The Solar System and the Universe", GS Philipp-Weiß, Fürstenfeldbruck, Germany (2019)
- "Os buracos negros no centro das galáxias/ The black holes of galactic centres", Escola Raul Proença, Caldas da Rainha, Portugal (2019)
- "Breve História do Universo/ Short History of the Universe", Escola D. Pedro V, Lisboa, Portugal (2014, 2015)
You are welcome to contact me via email if you would like me to deliver a talk (in English, German or Portuguese) on these and other topics at your school.
