Asko Parpola has been studying the Indus script for over 40 years at the University of Helsinki in Finland and is co-editor of collections of all seals and inscriptions in India and Pakistan. He has led a Finnish team of experts through numerous approaches to the puzzle of one of the world's earliest writing systems. A grand summary of Dr. Parpola's work, Deciphering the Indus Script was published by Cambridge University Press in 1994 (paperback 2009). Dr. Parpola continues to publish actively and develop the Dravidian line of analysis. Most recently, he co-edited Vol. III, new material of the Corpus of Indus Seals and Inscriptions, after earlier co-editing the collections of Indian (1987) and Pakistani (1991) materials.
