He has published books and articles on such diverse issues as bioethics, computer ethics and the roles that science and technology play in the culture of developing countries. His concern is mainly on how science and technology can be integrated into the life-world of the people in the so-called Third World countries and what kind of ethical considerations can be obtained from such relation. A large part of this question concerns how information technology is integrated in the lifeworld of the Thai people and especially how such integration is expressed in the use of information technology in education. He has organized the second and third Asia-Pacific Computing and Philosophy conferences at Chulalongkorn University in 2005 and 2007. His works have appeared in The Information Society, AI & Society, Philosophy in the Contemporary World and Social Epistemology, among others.
