Computer Science provides technologies and solutions for computing, data management and Internet applications. Research areas include advanced database solutions, middleware systems and technology for knowledge management, user design for human-computer interaction, Web technologies, content management, services-oriented architectures and e-commerce, e-utilities and computer science principles and methodologies. Watson researchers do fundamental research in cryptography, computational biology and learning theory, among others. A focus area of IBM�s high performance computing work is protein folding, which combines sophisticated pattern-searching algorithms with advanced computational, data and analytic methods to assemble solutions that are potentially valuable for drug discovery.
