Welcome to my web site.
I am a historian of science working at the Centro Interuniversitário de História das Ciências e da Tecnologia, at the University of Lisbon (CIUHCT-UL), and I teach at the Master Program in the History and Philosophy of Science.

Here you'll find information on my research, my papers, books, and other topics.

Projects

The edition of Pedro Nunes's Works (Obras de Pedro Nunes), by the Lisbon Academy of Sciences and the Calouste Gulbenkian Foundation is still my most absorbing project. Presently I am terribly busy with vol. VII (Nunes' manuscripts). See the Projects page for updated information.

I am working with Rui Magone (Berlin) on the edition of Manuel Dias' Tianwenlüe 天问略. You can check the blog where we discuss our progress in detail.

Although formally ended as an FCT Project, the Cataloguing of the scientific manuscripts at the Biblioteca Nacional de Portugal continues. More than 1000 manuscripts analysed and catalogued so far -- and some nice findings I will be reporting here...

Still working with Conceição Tavares on the Bibliografia de História da Ciência em Portugal, for the years 2005-2008. It's more than a book. We plan to set up a database with all bibliographical references.
