The ICTP Prize Selection Committee has announced that the 2001 ICTP Prize in honour of Hans Bethe in the field of high energy physics has been awarded to Soo-Jong Rey, a researcher at Seoul National University Centre for Theoretical Physics in Korea. Soo-Jong Rey has authored more than 90 articles in the fields of string theory, cosmology and particle physics. In the early 1990s, his work on the non-perturbative aspects of string theory set the stage for the discovery of various dualities in string theory later that decade.
