Biography for the 2014 SEG Near Surface Global Lecturer
Koichi Hayashi is presently a Software Development Manager at Geometrics in San Jose, California. Over the past 20 years, he has worked as a research geophysicist focusing on providing better tools and algorithms for near-surface geophysical methods. He earned a bachelor's degree in Earth Sciences from Chiba University, a master's in Earth Sciences from the Massachusetts Institute of Technology, and a PhD in Earth Resources Engineering from Kyoto University. His main research areas are seismic refraction, active and passive surface waves, finite-difference seismic modeling, and traveltime inversion. He is the main developer of the widely used SeisImager program and has incorporated many of his theoretical developments into the software, making SeisImager a premier surface-wave, refraction, and downhole processing package available today. He regularly presents papers at SEG meetings and has published over 30 papers in journals and proceedings of SEG, EEGS, and SEGJ. In 2006, he received an award from SEGJ for the development of surface-wave methods. He presented in an SEGJ one-day seminar on the surface-wave method. He is a member of SEG's Near-Surface Task Force and of the International Affairs Committee of SEGJ.
