I have 30 years of experience, and specialize in the field of biomechanics, with specific knowledge in the areas of bone failure, gait analysis, and fall risk determination. I have published on such topics as effects of age on bone strength, gait analysis, and reliability of measurement techniques. I have had the good fortune to have been invited to lecture on the topics of gait and balance in many parts of the world including Europe, South Africa, Australia, and the Middle East.
