Prof. Dr. Zong Woo Geem works for the Department of Smart City at Gachon University in the Republic of Korea. He has obtained a B.Eng. from Chung-Ang University, an M.Eng. and Ph.D. from Korea University, and an M.Sc. from Johns Hopkins University, and research at Virginia Tech, University of Maryland-College Park, and Johns Hopkins University. He invented a music-inspired optimization algorithm, Harmony Search (HS), which has been applied to various scientific and engineering problems as well as social and cultural problems. His research interest includes theoretical background (e.g. novel human-experience-based derivative of HS rather than existing analytic-calculus-based derivative) and problem-specific development (e.g. problem-specific operator of HS) of phenomenon-mimicking algorithm and its applications to sustainability & culture issues.
