Dr. Katherine Ramsland, Ph.D., began her career as an undergraduate with a double major in Psychology and Philosophy. She then went into a master's program at Duquesne University that combined them, but moved on to a Ph.D. in Philosophy. Having spent time as a Therapist and an Experimental Psychology Lab Assistant, she ultimately decided to pursue another Master’s Degree at John Jay College of Criminal Justice—this time in Forensic Psychology, which changed her life. Now, she’s a Professor of Forensic Psychology at DeSales University and the author of 60 books. Dr. Ramsland loves exploring the developmental trajectory of people who become criminal offenders—especially serial killers—as well the fine details of individual casework. These have been her passion for more than two decades, and she tries to pass along this interest to her students.
