I have 50 years of experience, and specialize in the field of vibration with specific knowledge in the areas of structural vibration, vibration and noise reduction and structural damping. I have published on such topics as vibration criteria for healthcare facilities, design of facilities with extreme vibration requirements and prediction of sound-induced stress. I have testified on hearing damage from loudspeakers and injury from forklift. I have held senior positions in several technical societies and received a number of technical awards. I have presented courses and lectures on four continents.
