Wen Jeng ChenWen Jeng Chen, Ph.D., P.E., Fellow ASME, is the developer of DyRoBeS(c) and the founder of Eigen Technologies, Inc. Dr. Chen has been working in industry after receiving his Ph.D. in 1987. He is a registered Professional Engineer in the State of Illiois. Dr. Chen was awarded the H.H. Jeffcott Award for outstanding paper on rotating machinery. He made significant contributions in the area of rotating machinery as a practical industrial engineer and outstanding researcher. His achievements have been both analytical and design-oriented and have spanned a broad spectrum of topics within the general area of rotating machinery. Dr. Chen is clearly a versatile and prolific researcher and is well respected in the rotordynamics communities, both academic and industrial.

Edgar J. Gunter, Jr. Ph.D., Fellow ASME, is the founder of RODYN Vibration Analysis, Inc. He has worked in the field of vibrations of rotor machinery and fluid bearings for over 40 years and written over 150 technical papers and reports on various aspects of the dynamics of rotating machinery, fluid film bearings and balancing. Dr. Gunter is now a professor emeritus, after teaching for 34 years in the Department of Mechanical, Aerospace and Nuclear Engineering at the University of Virginia. He has worked with industry and government on various rotor dynamic and vibration problems. He has also consulted with NASA and participated in hands-on work on the space shuttle program in it's early days. NASA engineers utilize DyRoBeS(c) software extensively, and Dr. Gunter has presented numerous on-site training courses at NASA on the use of both the rotor dynamics and bearing components of the software.
