I have 15 years of experience in the field of psychiatry, with specific knowledge in the areas of high profile cases, civil, and criminal. I have published on such topics as psychological analysis of celebrities, terrorism, and police brutality. I have testified 99 times on topics such as child abuse, sexual harassment, and murder. In addition to being a psychiatric expert witness, I analyze news (including legal issues and trials) on top TV and radio shows, and in print. I am also an internationally known speaker and author.
