Journalism
For Global Voices I have participated in their Civic Media Observatory project. I collaborated on two works:
Portugal and the myth of the good colonizer.
If on welfare, better learn dutch and be a man.
Opinion pieces
I have published two opinion pieces in Dutch (if you wish, the built-in Google translate does quite a good job at translating):
Voor Trouw: Kijk ook eens met de niet-westerse bril naar de oorlog.
Voor Het Parool: Opinie: "Een Marokkaanse jongen die ’s avonds tegen me praat wantrouw ik eerder dan een witte jongen, jij niet?"
Data Science
Data analyst
(March 2024 - Present)
As a data analyst at Onja, I analyse candidate selection and course impact, and help with multiple data-related efforts throughout the organization. As Onja is a start-up, I am often involved in other parts of the organization.

I have written my thesis with Professor Alcides Fonseca on interpretable feature learning using Grammar-Guided Genetic Programming (GGGP) as part of the CAMELOT project. As part of the thesis, we build Genetic Engine, an open-source GGGP framework in Python. Afterwards, we researched GGGP-based feature learning and GGGP individual representations.

Worked with Tiago Guerreiro through a Master fellowship, researching gait analysis for motor impaired people. Experimented with transfer learning to personalise gait analysis to make gait analysis more inclusive.

Research and Development
(Feb 2019 - Aug 2020)
As a Data Scientist and a Software Engineer I was part of the Research and Development team at Impact Institute. I started of as an intern, and later worked as a Project Support Officer, working with Impact Institute for a total of one and a half year. Our main achievement was the creation of the Global Impact Database.
