Yasuyuki Horie is a former senior scientist, Energetic Materials, Munitions Directorate, Air Force Research Laboratory (AFRL), Eglin Air Force Base (USA). Currently he serves as a consultant at AFRL through the University of Dayton Research Institute, and at Sandia National Laboratories, Albuquerque. His work and interest are concerned with high-pressure shock compression of condensed matter focusing on thermo-chemical behavior of both inert and energetic materials. He received his Doctor of Philosophy degree in physics at Washington State University. He was a professor at the Department of Engineering Science and Mechanics and Civil Engineering, North Carolina State University 1969–1999, and a technical staff member at Los Alamos National Laboratory 1999–2005. He moved to AFRL in 2005 and retired in 2012. He was honored with a Science and Engineering Award from the US Air Force in 2006, a Technical Achievement Award of the Year from the Munitions Directorate, Air Force Research Laboratory (AFRL/RW) in 2009, and the Prof. Glass Memorial Lecture Award from the Shock Wave Research Society of Japan in 2010. He has been a fellow of the American Physical Society since 2001.

• Beginning.- Ph.D thesis on phase transition in iron.- Sojourn in Great Britain.- Back to the USA.- Mid-life Turning Points.- New international collaborations at NCSU.- LANL.- AFRL, Eglin AFB.- Life after retirement.
