Erik works in UC Berkeley's School of Information where he teaches Web
Architecture and XML Technology courses. He has been working with XML
since its invention, and is mainly interested in anything related to XML
documents and the models they represent, which means schema languages,
transformations, Web services, and query languages. His second major
field of interest is Web Architecture and how to use it to build open
information systems. The main application areas he is currently looking
at are mobile Web and location, and e-learning and Open Content.
