About me

I am currently a Research Engineer at Google DeepMind, in London Zurich. Previously, I worked in the Query Formulation team at Microsoft Bing and did research in Machine Learning and Computer Vision at Idiap Research Institute and École Polytechnique Fédérale de Lausane, both in Switzerland. I did my undergraduate studies at Faculty of Engineering of University of Porto, in Portugal, where I am originally from.

In 2011, I wrote a book in Portuguese, expressing my views of the world. In a collection of very small chapters, I touch a wide range of topics, such as: democracy, economy, education, entrepreneurship, transparency, sustainability, peace, etc.

If you are interested, you can read the full book in digital formats for free, or order a paperback copy.


Deep Reinforcement Learning in 25 minutes, for non-experts. This is talk I gave at Commit Porto 2018 for an audience of software developers, where I assumed no background in Machine Learning.


You can read my blog, which is mostly about machine learning, artificial intelligence and other computer science related topics.

Please refer to my Linkedin profile, which is normally up to date.


Some of the people I've worked with:


I believe that micro-credit is an useful tool to alleviate poverty, so I try to give my contribution. Check my Kiva Lender page. If you are interested in effective altruism, I also recommend having a look at GiveWell. If you are more into enjoying your holidays doing some volunteering, I can recommend IVHQ (I've been only in their Rio de Janeiro program)
