Physics Expert Witnesses
What is a physics expert witness?
Physics expert witness candidates typically possess an advanced degree and extensive experience in physics, or a related engineering discipline – depending on the specific technology or product involved. Biophysics expert witnesses, or medical physicists, use applied physics in medicine often for the diagnosis and treatment of cancer. The expert witness chosen may be a member of an industry organization such as the American Physics Society, the American Institute of Physics and/or the IEEE. In high profile cases, or litigation involving a significant financial stake, previous expert witness testimony experience is often a requirement.
What types of cases require a physics expert witness?
A physics expert often provides expertise in intellectual property matters such as a patent infringement or trade secrets dispute.
