As a patent law expert witness, I have more than 5 years experience as a physician, attorney, and acupuncturist, specializing in health care financing and regulation, intellectual property, and public health. I have additional experience in the challenges big data and artificial intelligence pose to patent law; the role of comparative effectiveness research in drug regulation; and the intellectual property implications of innovations related to human biological processes. My career also includes offering my services in Southern California as an expert witness with consultations and courtroom testimony.
