Welcome to Sergi Castellano's home page.

I am biologist working in computational and evolutionary biology, with particular interest in the application of these fields to selenium biology and other basic questions in biomedical research.

I earned my Biology degree at the Universitat de Barcelona, spending my last semester in Paul Higgs' lab at the University of Manchester. Back to Spain, I pursued a PhD in Bioinformatics in Roderic Guigó's group at the Universitat Pompeu Fabra and the Centre de Regulació Genòmica in Barcelona. I continued my research in two short stays with Marla J. Berry at the University of Hawaii and Andrew G. Clark at Cornell University in New York. In all these labs, I worked on the computational identification and annotation of selenoproteins and population genetics/molecular approaches to their evolution.

I am currently in Sean R. Eddy's lab at the Janelia Farm Research Campus of the Howard Hughes Medical Institute in Virginia. I work on probabilistic algorithms for sequence analysis. In mid 2010, I am moving to the Department of Evolutionary Genetics at the Max-Planck-Institut fur evolutionare Anthropologie to lead a group on computational genomics.
