DR. JONI JOHNSTON

WELCOME!

I've always been interested in understanding the criminal mind. It's why I became a forensic psychologist. Today, my job is to provide insight in areas where law and psychology intersect - when a mentally ill defendant commits a crime, when a disgruntled employee threatens violence, when a violent offender is about to be released on parole. You might find me testifying as an expert witness, evaluating an inmate in a maximum security prison, or investigating a harassment complaint.         

But forensic psychology applies to more than just the courtroom; it touches all of us. That's why it's important to me to share what I learn with the general public, through my Psychology Today blog (Human Equation), as a contributing writer for True Crime: Case Files Magazine, as a consultant on true crime shows, and through my books (such as The Complete Idiot's Guide for Psychology). We all know knowledge is power. When it comes to understanding the criminal mind, knowledge can mean the difference between life and death.
